INTRODUCTION The purpose of this document is to provide miscellaneous hints and troubleshooting tips for UnixWare 2.x, for information that does not seem to fit elsewhere in the FAQs. If you have free UnixWare 2.1.2 also see the URL http://www.freebird.org/freeUW.html first. Some of the installation information is extracted from the UnixWare 2 Installation Handbook - please consult that for further information. For information on invoking the DCU - see the Autoconfiguration FAQ. Much information has been gathered from the netnews, some from the World Wide Web Technical support databases, see the acknowledgements section. Its maintainer is Andrew Josey (andrew(a)tamarix.demon.co.uk). Suggestions and contributions welcome.

SCO has a set of Web pages containing hardware compatibility for all of SCO's server products. Certified hardware for UnixWare 2 has been merged into those pages which can be found at http://www.sco.com/Third/hch. The freebird project has a hardware compatibility register, where UnixWare users can register working hardware configurations. See http://www.freebird.org/hwcompat.html. T1) How do i find out whether UnixWare supports my Host Bus Adapter (hba) UnixWare2 supports a selection of HBA's on the boot disk and a separate HBA disk. This section describes the support for UnixWare 2.01 and UnixWare 2.02/2.03 (it would be helpful if someone suggested how to update this section for 2.1 -mod) The UnixWare 2.03 HBA diskette is available from: ftp.sco.com:/UW20, or ftp.freebird.org:/unixware/Patches2 Due to problems with the 2.03 README file, the changes in 2.03 are not fully described here but the 2.02 HBA set is, one change that is known is the addition of support IDE CDROM support (see later in this Install section). Section A: UnixWare 2.01 HBA Support (see later for 2.02 HBA) Some 2.x drivers will automatically detect the interrupt, I/O port, memory address and DMA channel. When this applies to the driver, "auto" will be listed under "Irq/IO/Mem". Other UnixWare 2.x drivers require that you use DCU (Device Configuration Utility) to configure the driver or set the scsi controller to the predetermined interrupt, I/O port, and/or memory address before installation. Using DCU, these can all be changed after the UnixWare installation.

The driver will not load on Compaq platforms or integrated 53c8xx's on Compaq 53c8xx EISA/PCI host bus adapter boards in a Compaq platform. See the seperate 2.02/2.03 driver for 53c8xx support for Compaq platforms.) ------- Tricord ------- PowerFrame iiop auto 2.0.1 hba disk ------- UltraStor ------- UltraStor has not made any drivers available for 2.x at this time. ------- Western Digital ------- 7000 ISA wd7000 15/350/CE000 boot disk ** Problems arise in a some cases when scsi chipsets have been placed directly on the motherboard or on a 3rd party controller. Often the controller is not given the full functionality the chipset was intended to have. *** The adsa driver will not auto configure with the Adaptec 2840/42 controller. The fundamental problem is that the VLB (Vesa Local Bus) can't tell the system what kind of slots or cards they have. As it happens, the adsa driver (for the Adaptec 7770 chip) is mainly targeted for the 2740 card, an EISA device. To make the adsa driver work with the 2840/42 controller, enter the DCU when prompted after loading the HBA diskette. (If you are not installing, you will not be prompted to enter the DCU). Go to "Software Drivers", and "Host Bus Adapters". Move the cursor to the "adsa" entry (note that the AHA-2842 is not mentioned, but this is the right driver nevertheless). Hit for "new". Change the ITYPE field from 4 to 3. Change the interrupt number to match the value the card is set to. Hit to save and exit, and then exit out from the DCU, saving your changes. This procedure can be repeated if a second 284x is to be used during the installation. In other words, hit again for the second card. Section B: : HBA202 - UnixWare 2.02/2.03 HBA drivers The 2.02/2.03 HBA package contains new drivers as well as all maintenance, enhancements, and fixes for UnixWare 2.01 HBA drivers. * Highlights The following is a list of new and enhanced drivers which are included in this package: - fdeb - Future Domain HBA Driver - fdsb - Future Domain HBA Driver - wd7000 - Western Digital HBA Driver - zl5380 - Media Vision HBA Driver - amd - Advanced Micro Devices HBA Driver - blc - Bus Logic HBA Driver - c8xx - Symbios Logic HBA Driver - dpt - DPT HBA Driver - adsl - Adaptec HBA Driver - ida - COMPAQ HBA Driver - cpqsc - COMPAQ HBA driver * Features The following HBAs are new or enhanced for 2.02/2.03: - Future Domain HBA Driver fdeb The fdeb driver provided by this package has enhanced direct access to the SCSI peripherals (pass-thru) and extended read/write support. The default UnixWare configuration is interrupt 5 and memory address CA000-CBFFF. - Future Domain HBA Driver fdsb Enhanced direct access to the SCSI peripherals (pass-thru) and extended read/write support are provide in fdsb in this package. Also, support for the Future Domain PNP-1630 adapter has been added to the driver. The default UnixWare configuration is interrupt 11 and I/O address 140-14F. - Western Digital HBA Driver wd7000 Enhanced direct access (pass-thru) ioctl support is available in this release of the driver. The default UnixWare configuration is interrupt 15, I/O address 350-357, and memory address CE000-CFFFF. - Media Vision HBA Driver zl5380 Support for the Media Vision Pro Audio Spectrum 16 adapter is provided in the this package. Note that this support is SCSI only, and that support for audio on this adapter is not provided. The default UnixWare configuration is interrupt 10 and I/O address 388-38B. Interrupt and I/O settings should be verified using the Quick Start program provided with the controller (runs under DOS). - New Advanced Micro Devices HBA driver amd The new amd HBA driver is provided in this update. This driver supports the following adapters: Am53C974 PCscsi Am79C974 PCnet-scsi. Tagged command queuing is supported, and the UnixWare auto- configuration utility is responsible for configuring the adapter for use with the system. - Bus Logic HBA Driver blc blc has been modified to support the following adapters: BT-956C BT-956CD BT-7942 (RAID) These adapters and the blc driver support "WIDE SCSI," tagged command queuing (if enabled), and hot insert. The UnixWare auto-configuration utility is responsible for configuring the adapter for use with the system. - Symbios Logic HBA driver c8xx The 2.02/2.03 HBA package provides the Symbios Logic HBA c8xx. This driver supports the following PCI to SCSI adapters and controllers: Symbios Logic 8100S (adapter) Symbios Logic 8251S (adapter) Symbios Logic 53c810 (controller) Symbios Logic 53c820 (controller) Symbios Logic 53c825 (controller) Symbios Logic 53c815 (controller) Tagged command queuing, WIDE SCSI and hot insert are supported. The UnixWare auto-configuration utility is responsible for configuring the adapter for use with the system. The driver will support the Symbios Logic (NCR Microelectronics) 53c8xx family. The driver will NOT load on COMPAQ Computer Corporation's 53c8xx host adapters in COMPAQ machines. The user must use the update cpqsc driver for the 53c8xx in COMPAQ machines. - DPT HBA driver dpt The dpt driver has been enhanced to support WIDE SCSI, hot insertion/removal and EATA direct access to the SCSI peripherals (pass-thru). The Storage Manager utility is supplied by DPT directly. You can monitor the the controller and target devices via the Storage Manager, in addition to performing diagnostic and maintenance tasks. Tagged command queuing is still supported by the controller firmware without driver intervention. EISA and PCI versions of the DPT controllers are completely auto-configured and require no special configuration. ISA versions of the DPT controllers need to be configured as follows: I/O Address - 170 (also called "secondary"), Interrupt 15 and the controller BIOS can be configured at any non-conflicting address. - The New Adaptec HBA Driver adsl adsl supports the following adapters: AHA-2940 AHA-2940W AHA-3940 AHA-3944 AIC-7870 AIC-7850 WIDE SCSI peripherals may be used with the AHA-2940W adapter. The UnixWare auto-configuration utility is responsible for configuring the adapter for use with the system. - COMPAQ HBA Driver ida ida has been modified as follows: - support for more than seven disks - support for WIDE SCSI - corrected interaction with CIM agents - corrected operation of ida controllers with IDE compatible interfaces The UnixWare auto-configuration utility is responsible for configuring the adapter for use with the system. - COMPAQ cpqsc HBA Driver cpqsc The COMPAQ cpqsc HBA driver is updated in this release. The driver supports the following: COMPAQ Integrated 32-bit COMPAQ Integrated 32-bit Fast-SCSI-2 (CPQ4410) COMPAQ 32-bit Fast-SCSI-2 (CPQ4411) COMPAQ Integrated 32-bit Fast-SCSI-2/E (CPQ4430) COMPAQ 32-bit Fast-SCSI-2/E (CPQ4431) COMPAQ Integrated 32-bit Fast-SCSI-2/P (Symbios Logic 53C810) COMPAQ 32-bit Fast-SCSI-2/P (Symbios Logic 53C825) Support for WIDE SCSI peripherals, tagged command queuing, and hot insertion has been added. The driver will support COMPAQS Fast-SCSI-2 family of controllers. The driver will NOT support the Symbios Logic (NCR Microelectronics) c8xx host adapters. T1.1) Installation fails intermittently on my Adaptec 1542B, what should I do? Check the jumpers for the speed setting. Some cards will fail to install when the DMA transfer rate is set too high, say 8MB/sec. Change this to 5MB/sec and retry, this is typically removing jumpers 12 and 13 from block J5. T1.2) My system automatically detects two Adaptec 2940 PCI SCSI controllers when I only have one, what should I do? This is a well-known problem that affects some, but not all PCI motherboards. Obtain tf2069.tar (note that some of the other tf2069 files on the ftp site are corrupt, so get this larger file) to extract a new boot floppy for the AS as well as the PE. (NB, you still need the original install floppy 1 in order to license your installation -- see release notes of ptf2069 for more detail.) T1.3) The system does not recognise my Adaptec 1542CP, what should I do? I ordered an Adaptec 1542CF and got (instead) 1542CP. I have tried a first time installation of Unixware and can't succeed. DCU shows one device as UNKNOWN at the bottom of the list with parameters which can't be changed (as far as I can tell), and don't appear to match my board. Can I use the Adaptec 1542CP (the "P" is for plug and play)? The solution is to disable the Plug & Play feature in the Adaptec 1542CP's BIOS. Use IRQ 11 & 330 as the port address (as noted above for the 1542C). T2) What to do if the Booting UnixWare Message is not displayed Check whether the boot disk drive contains a diskette. If so, remove the diskette and reboot your system. Otherwise, you may have a system hardware problem. See the documentation provided with your hardware. Many add-on devices and cards come with configuration utilities. Check all the connections and run the configuration utilities. T3) What to do if the system Panics or Resets While Booting from the Install Diskette - for example on an IBM Thinkpad 755CX Problem. After booting your system with the Install Diskette, the UnixWare logo screen is displayed and then the system either displays a panic message or resets (the system FIRMWARE messages are displayed again). You can either try an alternate boot diskette from ftp.sco.com:/UW20/tf2069.tar This is known to work when installing on an IBM Thinkpad 755CX. If you still have a problem read on. This problem is typically the result of not running a hardware configuration program, such as the ECU or the CMOS setup program, before installing UnixWare. To fix the problem, run all machine and peripheral hardware setup programs provided by your hardware vendor and verify that your hardware is correctly configured. In particular, check your memory size/control, cache control, bus speed, and video specifications. See your hardware documentation for details. For example, this problem may occur if the correct amount of memory is not configured. (To determine the amount of memory on your system, either check your hardware documentation or CMOS settings.) If running hardware setup programs does not solve the problem, then there may be a memory problem. You can try to manually set the amount of memory on your system as follows 1. Reboot your system. 2. When the Booting UnixWare... prompt or the logo is displayed, press the The interactive boot session prompt, [boot]#, is displayed. 3. Set the MEMRANGE parameter by typing MEMRANGE=0-640K:256,1M-nM:16896 GO where, n is the amount of available contiguous RAM in megabytes. 4. Continue the installation of your system until you are asked to reboot the system. 5. When prompted to reboot your system, invoke a UnixWare shell by typing -- The VT0> prompt is displayed. 6. Update the /stand/boot file by typing echo "MEMRANGE=0-640K:256,1M-nM:16896" \ >> /stand/boot 7. Type -- 8. Continue the installation . T4)Your PCI system hangs or panics during installation Symptom: This problem will normally be seen as a system panic during the initial boot sequence, with the following format: Kernel Mode Address Fault on user address ... Background: UnixWare 2.1 provides support for PCI systems which conform to the PCI 2.1 bus specification. The installation assumes that PCI systems will provide support for all PCI 2.1 BIOS calls, but some motherboards only conform to the older PCI 2.0 standard. Solution: If you suspect that your system has this problem perform the following procedure. 1. Press reset (or power the computer off, then on again if you do not have a reset button). 2. Wait for the Booting UnixWare... prompt. Hold the space bar down until you get the # prompt for an interactive boot session. 3. Hit the key to get a fresh prompt, then type the following commands: # PCISCAN=2.0 # go 4. If you still experience the same problem it is likely that your system makes non-standard (or very old standard) PCI BIOS calls. You could follow the above procedure, setting PCISCAN=NO instead of PCISCAN=2.0. However, this will mean that the system will not automatically detect PCI peripherals. If you do this you will need to manually configure your PCI devices using DCU. It is probably easier, safer and less time consuming to get hold of a better motherboard than to attempt this. 5.When prompted to reboot your system, invoke a UnixWare shell by typing -- The VT0> prompt is displayed. 6. Update the /stand/boot file by typing echo "PCISCAN=2.0" >> /stand/boot 7. Type -- 8. Continue the installation. T5) The system hangs on a reboot. - If your computer has a hard disk drive greater than one gigabyte and you have an Adaptec 1542 SCSI controller with extended translation enabled, disable the extended translation. - If your computer already had an operating system (for example, OS/2) before installing UnixWare, it may have a "boot code" on the hard disk which is incompatible with UnixWare. If this is the case, UnixWare will not boot and you may receive a message such as Cannot Load User Driver or No Active Partition Found. You should obtain the osbs from ftp.abs.net:/unixware/freebird/bootselector. T6) You've installed a new kernel and it fails to boot. You can restore the old UnixWare system as follows: 1.Press reset 2.Wait for the Booting UnixWare... prompt; then press the key to begin an interactive boot session. 3.When the [boot]# prompt is displayed, type KERNEL=unix.old go T7) What to do if your Resource Manager Database gets Corrupted Problem. The system will not boot and an error message indicates that the resource manager database, /stand/resmgr, is either corrupted or missing. Solution. Reboot UnixWare. Press when the Booting UnixWare... prompt is displayed. The interactive boot session prompt, [boot]#, is then displayed. Type RESMGR=resmgr.sav GO This loads a backup copy of the resource manager database. You system should then reboot. When the system comes up you may want to invoke the DCU to verify that all device driver parameters are set correctly. A corrupted or missing resource manager database is normally the result of improper changes made when adding/modifying hardware parameters. T8) Your machine has the Power Saver Option Enabled Problem. Installation fails at random points after the hard disk is set up (or the message WARNING: Disk Driver Request Timed Out, Resetting Controller is displayed after a successful installation) on systems with the "Power Saver" option (also referred to as "Power Management" or "Green PC") enabled. Solution. Turn off the "green/energy star" power saving time outs in the system BIOS. (Refer to the hardware manual for details.) T9) UnixWare does not see the additional 16 MB added to my machine with the existing 16 MB, what should I do? If it's an ESIA machine it's very important the the EISA config is run correctly. And then there is page 132 of the Installation Handbook. "Create a /stand/boot file with the following entry: MEMRANGE=0-640K:256,1M-16M:512,16M-nnM:8704 where nn equals the actual amount of RAM memory, in megabytes. see boot(4)" T10 )Is there support for IDE/ ATAPI CD-ROM drives? You need either hba203.tar or tf2197.tar These can be obtained from ftp.sco.com:/UW20 tf2197.tar: 102400 bytes TF2197 - IDE Host Bus Adapter Driver -- 11-15-95/20:12p PTF2197 provides UnixWare 2.01 with support for the IDE HBA driver for use with ATAPI CD-ROM devices. The following ATAPI CD-ROMs have been tested (other drives may or may not work): Mitsumi ATAPI CD-ROMs with firmware of BB03, BE01L, BB04, and BS01. Toshiba ATAPI CD-ROM XM-5302 with firmware of TA1095. Sony ATAPI CD-ROM CDU76E-S with firmware of 1.0C. If you are installing afresh: (1) Boot off the UW2.01 boot floppy (2) When prompted install 2.03 HBA disk (3) Enter DCU Software Drivers Host Bus Adaptors Deselect all but the ide driver Select F5 for new The primary PCI IDE controller, if used, should be configured with: IRQ 14 IOStart 1F0 IOEnd 1FF MemStart 10000 (THE DEFAULT VALUES) MemEnd 10001 Select F5 for new The secondary PCI IDE controller, if used, should be configured with: IRQ 15 IOStart 170 IOEnd 17F MemStart 0 MemEnd 0 NOTE on MemStart and MemEnd values: ------------------------------------- Kevin Bulgrien reports: If you have trouble with zeroes, using "-" for both IDE drivers' MEM Start and MEM End addresses is perfectly fine. In fact, given that the standard IDE controller does not usually map any memory address, my _estimation_ is that the default values on the DCU's new instances of ide are probably not really legitimate. (END Note) Go into HW Configuration again, if you have three ide controllers switch the first to N Then exit, save changes and apply If you have a running system, you can pkgadd the hba diskette, and then enter the dcu. (Before attempting this you may want to ensure you have created your emergency boot diskettes). If installation fails and you cannot boot the operating system, the recovery procedure is as follows: 1.Press reset 2.Wait for the Booting UnixWare... prompt; then press the key to begin an interactive boot session. 3.When the [boot]# prompt is displayed, type KERNEL=unix.old go If that does not work then Before the go add RESMGR=resmgr.sav This loads a backup copy of the resource manager database. Your system should then reboot. Kevin Bulgrien reports further experiences: The machine: 486DX4-120, DTC-2278 VESA Bus IDE controller, 1.6GB Maxtor Master on primary IDE channel, Mitsumi FX400 Master on secondary IDE channel, Partition 1 is bootable Novell DOS 7 and is 256 cylinders or max size for 8K clusters under DOS; Partition 2 is 256 cylinders and is defined as an extended DOS partition used as "D:" when booted on DOS; Partition 3 is 277 cylinders to be used for the bootable UnixWare installation. IDE controller/BIOS is set to use LBA, Block Mode, and 32 bit transfers - works great on DOS. The symptoms: If you are installing UW 2.01 from an IDE CD-ROM on top of an existing UNIX partition, you will not be able to do so without first deleting the UNIX partition. I made a mistake on an install, (or, if you will, so screwed things up that I wanted a clean reload instead of a fixed up install), and decided to reinstall from CD and wipe out the old installation. No matter what you do, the boot disk for 2.01 WILL NOT allow you to reload from CD as long as there is a valid UNIX partition defined. In fact, no matter what you pick at the install screen where you are given the chance to "Proceed with the installation", or "Enter the DCU", you will never get to the DCU to configure the ide channels. You always proceed directly to the options for install - which DO NOT list the CD as an option. This screen only comes up after a very lone wait of about 5 minutes. Repeat, there is no way to access the DCU to configure the IDE to allow use of the CD-ROM drive! I tried different ways around this, ie. load order of the HBA and TF2197 HBA, warm start, cold start, retries in case I mistyped something out of frustration, set active partition to DOS partition, all to no avail. The fix - yeah, right - NOT! Delete the UNIX partition. Seem simple? Not so. The DR-DOS 6 disk which comes with UW 2.01 does not have an FDISK which allows deletion of non-DOS partitions. Novell DOS 7.0's FDISK does not allow this either. I had to find an MS-DOS boot disk with FDISK on it. MS-DOS' FDISK does allow you to delete non-DOS partitions. Once the UNIX partition is deleted, installation proceeds normally. Surely this is a bug in the TF2197 HBA? Does the same thing happen for the 2.03 HBA? I will shortly be finding out. Are there any dissenting facts concerning this work-around? I would be delighted to learn of a way to not have to delete the UNIX partition. Conjecture about other results of this possible bug: I have never successfully used the Emergency Boot disks. To be fair, I have not tried them more than a couple of times. I have noticed, without reading details, many messages about the emergency boot disks not working. Is it possible that the problem that causes installs to fail may cause other boot from floppy procedures to fail? I do not know, but would appreciate feedback on this. Other problems with TF2197 Upon boot, immediately following the NUC startup messages, the following warning message appears - for me, only when TF2197 is installed: WARNING: EXTRA BYTES OUT 55476 - or- WARNING: EXTRA BYTES IN 36 I have not determined if there is a pattern which would let you predict which one of the above two messages occurs upon boot up, but one of these messages always appears. If I were to guess, I would say that the OUT message is a cold boot, and the IN a warm boot, but again, I have not figured out the pattern. These messages occur no matter which way I answer the MEM Start and MEM End entries in the DCU - Just thought I'd mention that. T10.1) Sony CD33A & Unix 2.01 Install Kevin R. Bulgrien (102174.1561@compuserve.com) reports: Please note that use of the non-SCSI Sony CD33A CD-ROM drive places restrictions on your configuration of the CD controller: I am using a Sun-Moon-Star controller, but I suspect that these items are also relevant to any controller for the Sony drive. Also note that I am relating this information with regard to the "sony" HBA that comes on the UnixWare 2.01 HBA diskette. As indicated by the Novell "UnixWare 2.0 Installation Handbook", but which bears repeating, the CD will only be usable when the controller is set to IRQ 5, I/O address 320-323, Memory addresses 0-0, and DMA 1. You may want to continue reading if you use a Sony CD33A, and if: 1) You try to use the CD controller at alternate IRQs, DMA channels, or I/O addresses. 2) You have a sound card - especially older ones with hardware straps that are used to configure the card. Here follows my findings on the above listed situations: IRQ 5 a) If not set to 5, the CD may very well be detected. However, when the UW 2.0 install CD is checked, right before installation begins, an error will indicate that the install CD is not in the drive, or the CD is damaged, and unreadable. b) Many sound cards use IRQ 5 by default. A sound card on IRQ 5 will effectively disable a CD controller configured with IRQ five. The CD is detected, but is unusable. BE AWARE that older Sound Blaster cards, and others, I assume, have straps that set the IRQ, BUT, you can change the IRQ with software after DOS boots. The result is that you may actually use another IRQ for your sound card, but, when UnixWare boots, the DOS configuration program is not run to set the IRQ, and the IRQ defaults to the strapped settings - which may be different than the settings you use all the time under DOS! DMA 1 a) Ditto the above notes for this setting. The controller I use will allow no DMA (Polled Mode), or DMA 1-3. No DMA, or DMA channels other than 1 will not prevent the CD from being detected, but will prevent the CD from being readable. b) Same warning goes with regard to strapping, if any, on your sound card. If you are going to have a DOS bootable partition, and want your sound card to be most usable with both, I believe that DMA 3 is the second best choice for the 8-bit sound driver DMA channel. (DMA 5 is commonly used for the 16 bit sound driver.) I/O 320-323 (MEM START & END) I believe, if I remember correctly, that alternate addresses cause the CD to be undetectable - I may be wrong though. The symptoms may be the same as for IRQ and DMA settings. DRQ My controller has settings for no DRQ or DRQ 1-3. I have not experimented with these settings so as to be able to draw conclusions on the results of different settings, however, I detect no problems at all when setting DRQ 1 - which seemed to match up with DMA 1? Maybe this is a dumb conclusion - Any comments from anyone on this? T11) Installing Windows 95 on the same disk as a UnixWare partition overwrites the boot loader. What can I do? Install the osbs boot manager, this can be obtained from ftp.freebird.org:/unixware/freebird/bootmanager. osbs can also let you support multiple operating systems on the same machine, say Windows 95, Windows NT , Linux and UnixWare. It presents a menu when booting for which one to select. T12) Desktop tools stop working. Critical system commands such as tfadmin, no longer execute. This causes administration tools in the desktop to not function. These symptoms could occur after doing a backup and restore of system files, or after doing pkgchk -f. TROUBLESHOOTING To determine if the filepriv database is out of sync, as superuser run the command: initprivs CAUSE System commands such as passwd, tfadmin, ftp, etc. rely on the filepriv database to be correct. If a file mentioned in the filepriv database has been modified on the file system in any way, including simply touching the file, and that change is not reflected in the filepriv database, the command will not execute or will not function properly. One way to cause a lack of syncronization between the file system and the filepriv database is by doing pkgchk -f, which goes through the /var/sadm/install/contents file and compares file attributes in the file, with those on the file system. If there is a discrepancy between the two, pkgchk changes the file attributes on the file system to match the contents file. Once the file on the file system has been modified, the filepriv database is now out of sync with the actual file. This will cause the symptoms above to occur. Another way the filepriv database can become out of sync, is by backing up and restoring system files. This causes the 'last update' time of the file to be modified on the file system, which does not match the last update time in the filepriv database. SOLUTION To syncronize the filepriv database with the file system, run the command: /etc/security/tools/setpriv -x To check the filepriv database at any time, run the command: initprivs Initprivs will return nothing if the filepriv database is in sync with the file system. T13) Desktop tools stop working when using a monochrome vga monitor This can be caused by using a monchrome (gray-scale) vga monitor. Checking /tmp/xdm-errors shows some error messages. The X Server does not find enough colours to function. Several work-arounds exist: (1) Reboot the system. When the red Novell logo appears, hit enter to get to the interactive boot prompt. Once there, type "go" and hit enter. The system will come up and will look and function properly. (2) Disconnect the monitor from the VGA card during boot. Once the system has had time to come up, connect the monitor and it should function correctly. (3) Connect a color VGA monitor for boot. Once the system is up, the monitor can be swapped for the monochrome and it should function properly. (4) There have been reports that simply having the monitor turned off during boot also works. However, this could not be reproduced on a consistent basis. Each time the system is rebooted, one of these methods must be used. T14) How do I configure Mosaic to change its Home page and fo
