- GENERAL & KNOWN INSTALL PROBLEMS
- --------------------------------
-
- ************************
- MEMORY PROBLEMS
- ************************
-
- Common Symptom: Trap 2, Trap 6 or other Trap at
- 60000x:9084.
-
- These problems are caused by:
-
- Mismatched memory simms (from different manufactures) -
- this is especially common if you recently added memory to
- your system, or if it was assembled from parts (not a
- recognized brand of clone).
-
- Mismatched memory simms (different classes) 1x9 simms
- cannot be mixed with 1x3 simms. Also, the 1x9 simms seem
- to be more reliable than the 1x3 simms.
-
- Slow memories on 486 machines (you may need 60 or 70ns
- memories).
-
- Cache problems.
-
- Solution: Replace memory and/or tune wait states, disable
- cache during install, turn turbo switch off.
-
- ******************
- SCSI PROBLEMS
- ******************
-
- These problems are caused by:
-
- incorrect BIOS
-
- need OS/2 compatible driver from manufacturer
-
- incorrect identification of adapter by OS/2
-
- mismatched settings of SYNCH/ASYNCH mode for SCSI
- controller, hard drive, causes slow drives, misssing icons
- - see OS2TNT, V2TECH
-
- Solution: Update BIOS, get driver from manufacturer, change
- settings.
-
- Known problems:
-
- AMI SCSI - slow, noisy disk - BASEDEV workaround - see APAR
- II06081
-
- FUTURE DOMAIN 16XX SCSI controller - hang on LOGO screen
- after reboot following good install - check for interrupt
- conflict - see APAR II06081
-

- to PROCOMM - see APAR # II06081
-
- Early versions of IBM 16-bit SCSI adapters - update
- microcode - see APAR # II06081
-
- dependencies - stick with IBM and Toshiba SCSI CD-ROM
- drives - others later - see readme
-
- Removable media support - Bernoulli (IOMEGA), and SyQuest -
- support is limited, treats them like big floppies - see
- readme
-
- All Adaptec adapters - SCSI hard disks must be configured as
- SCSI target ID 0 or 1 to be able to start up from that hard
- disk - see readme
-
- BIOS will not recognize - configure as non startup drive -
- see readme
-
- Adaptec AHA-174x adapter with IBM WDS-3180 80MB SCSI, IBM
- WDS-3160 160MB SCSI - Adapter will not recognize in
- 'STANDARD MODE' (AHA-154x emulation). Adapter should be
- configured in 'ENHANCED MODE' - see readme
-
- Future Domain TMC-850/860/875/885 w/BIOS revision level 7.0,
- and Future Domain TMC-1660/1670/1680 w/BIOS revision level
- 2.0 can cause "Disk Read Error" on installation disk for
- model 35 and 40 - need BIOS upgrade - see readme
-
- AMI "Fast Disk" and AMI "Fast Disk II" SCSI adapters are
- incorrectly recognized as Adaptec adapters - see readme for
- workaround
-
- Always IN2000 SCSI adapter - causes Internal Processing
- Error - need BIOS upgrade VCN1-02 - see APAR # II06081
-
- Quantam Plus Hardcard - need EPROM upgrade - see APAR #
- II06081
-
- SUMO SCSI adapters don't seem to work with OS/2 - talk to
- manufacturer
-
-
- ********************
- FDISK PROBLEMS
- ********************
-
- Some common problems:
-
- selections to dump or more disk.
-
- Insufficient disk space for swapper file growth on low
- memory systems - suggest install selections to dump or more
- disk.
-
- Incorrect setup information in CMOS memory for hard drive
- being used - see if it works under another operating
- system.
-
- Slow, noisy disk or FDISK errors (especially on RLL, MFM, or
- ESDI disks) - BASEDEV workaround - see APAR II06078
-
- Nonstandard or out of date BIOS (especially with IDE drives)
- - disk inaccessible or FDISK errors. Look for Phoenix or
- AMI standard BIOS and check dates in MORETIP or info APAR
- #II06078
-
- Incorrect identification of adapter by OS/2
-
- Trying to install on a drive which was compressed using a
- stacker utility - suggest uncompressing the disk or
- reformatting.
-
- Trying to install over a Beta version of OS/2 2.0 (1.3 is
- OK) - reformat first.
-
- Trying to install HPFS with less than 6M of memory - dump
- HPFS or get more memory.
-
- Trying to install on less than 4M (user may think he has
- 4M, but some cache arrangements or ROM to RAM remapping can
- steal some) - try to disable these features in CMOS setup.
-
- Disk corruption/failure (it won't even support DOS) - try
- high and low level format or get new drive.
-
- Quantum IDE hard disks require a free ROM update from Quantum.
-
- Install hangs on Disk 1 - this may be caused by having disk
- caching enabled on the drive controller card - try
- disabling it - also try turning off the controller's
- asynchronous memory refresh capabilities if applicable.
-
- already reside on the hard disk.
-
- IBM OS/2 2.0 can only be installed from Drive A, like DOS
- (unless you swap drive cables/change CMOS setup to fool
- system)
-
- Automatic migration of your DOS CONFIG.SYS and AUTOEXEC.BAT
- files can cause problems and is not recommended - recover
- using original config.sys in OS2 SYSTEM.
-
- If you have Windows 3.1 installed on your system do not
- migrate your Windows desktop.
-
- If you are using the IBMINT13.I13 driver to access an MFM,
- RLL, or ESDI hard drive, and the hard drive has more than
- 1024 cylinders, be certain your hard disk adapter's sector
- translation mode is enabled.
-
- COUNTRY.SYS problems are usually a symptom of a disk which
- is not recognized by OS/2, and may be caused by the
- following:
-
-
- Conflict with another device attached to the same controller
- card. Try removing anthing like a tape backup, which may be
- the cause of the conflict.
-
- On a P70, you need ECA068, contact IBM CE.
-
-
- ******************
- BIOS PROBLEMS
- ******************
-
- Many of the problems above have old bios as their root
- cause, so there is a lot of overlap between this and other
- problems - see details on how to check dates in MORETIP or
- info APAR #II06078
-
- Some common causes:
-
- - Wrong keyboard BIOS
-
- - Outdated video adapter BIOS
-
- In many cases these problems stem from old standard BIOS
- which is easily replaced, but in some cases, customer has
- old "custom" BIOS (manufacturer has included functionality
- specific to the motherboard on the BIOS). In this case
- there may be no upgrade path and the motherboard may need
- to be replaced.
-
- For more detailed information on BIOS, see INFO APAR II06082
-
- ************************************
- ADAPTER CONFLICT PROBLEMS
- ************************************
-
- On ISA machines, interrupt conflicts and memory mapping
- conflicts can cause a variety of problems. For example,
- many SuperVGA adapters use large chunks of upper memory,
- and many hard disk adapters have on board ROMs which can be
- mapped into this area as well. Also, Soundblaster boards
- use INT 7, which conflicts with many printers. Adapters
- must cooperate in their use of memory and interrupts and
- must not share address space or interrupts. Callers should
- be encouraged to check interrupt level settings on their
- boards. Also try removing cards that are not needed during
- install. Sometimes you will get a Trap D at 160:FFFxxxxx.
-
-
- ********************************
- VIDEO ADAPTER PROBLEMS
- ********************************
-
- Install problems resulting from video adapter conflicts
- typically occur on disk 6 or later. This is when the
- graphical install icons come up, and it is the first place
- where more complex calls are made to the video BIOS. One
- notable exception is the Oak video card. Try another video
- card during install, or try the card in an 8 bit slot
- during install. Try some different adapter DIP switch
- settings listed in your adapter manual. Make sure video
- card is in VGA mode with auto-sense turned off.
-
- Some specific problems:
-
- If you have a super VGA adapter, install should always be
- done as VGA. If you have an ATI Ultra, Vantage, or other
- 8514/A hardware compatible ada ter, use 8514/A driver for
- install.
-
- C0000005 is displayed on the screen during install (e.g.
- Western digital PVGA1D) - need fixed version of BVHSVGA.DLL
-
- Hang on Disk1 right after LOGO screen caused by OAK video
- card BIOS problem. Workaround is to patch loader file -
- see Install Adapter APAR
-
- video card is in VGA mode with auto-sense turned off.
-
- White screen after installation with no system activity -
- Try setting the video card to 8 bits and moving the video
- card to an 8-bit slot, also disable the auto-switching
- capability of the card if possible.
-
- Out of Synch/Install problems - caused by problems
- addressing card in 16-bit mode, switch to 8 bit mode (using
- jumpers or dip switches on board) and put in 8 bit slot.
-
- Install Adapter APAR
-
- Some super VGA cards have ROMs with conflicting addresses
- for some hard disks.
-
-
- **************
- OTHER PROBLEMS
- **************
-
- Failures very early on install disk (especially Zeos
- notebooks) - try applying patch to sysinstx.com in Install
- Other APAR
-
- Dual Boot feature does not allow boot back to OS/2 from DOS
- - there may be a disk cacheing utility or a TSR which
- blocks this.
