DESCRIPTION OF SYMPTOMS: | |||
When the IBM PC 300 Series - 486 Systems BIOS code switched CMOS | |||
banks, OS/2 (and the physical clock Device Driver) did not know | |||
that the CMOS bank was switched. If an IRQ 8 (realtime clock | |||
interrupt) came in when the CMOS bank was switched, then the system | |||
would hang because the clock DD would read the RTC CMOS locations | |||
on the 2nd bank when it should have read them on the 1st bank. | |||
The OS/2 virtual DD (VCMOS.SYS) did not allow writes to CMOS with | |||
addresses < 0Eh. So, the Rapid Resume data could not be written by | |||
a VDM (DOS session or windows). VCMOS.SYS virtualizes ports 70H | |||
and 71H. | |||
RESOLUTION: | |||
VCMOS.SYS will now virtualize ports 22H and 24H when on IBM | |||
PC 300 Series - 486 Systems or Aptiva. | |||
A fix must be applied to the OS/2 system to correct this | |||
problem. | |||
How to apply the fix | |||

TITLE: 950118 TIMING HANG ON IBM PC 300 SERIES - 486 SYSTEMS AND ON ALL APTIVA'S FROM THE 310 (2144-22P) THROUGH THE 530 (2144-66P).
DESCRIPTION OF SYMPTOMS:
When the IBM PC 300 Series - 486 Systems BIOS code switched CMOS banks, OS/2 (and the physical clock Device Driver) did not know that the CMOS bank was switched. If an IRQ 8 (realtime clock interrupt) came in when the CMOS bank was switched, then the system would hang because the clock DD would read the RTC CMOS locations on the 2nd bank when it should have read them on the 1st bank. The OS/2 virtual DD (VCMOS.SYS) did not allow writes to CMOS with addresses < 0Eh. So, the Rapid Resume data could not be written by a VDM (DOS session or windows). VCMOS.SYS virtualizes ports 70H and 71H.
RESOLUTION:
VCMOS.SYS will now virtualize ports 22H and 24H when on IBM PC 300 Series - 486 Systems or Aptiva. A fix must be applied to the OS/2 system to correct this problem.
How to apply the fix
In the fixes sent to you will be a file called VCMOS.SYS. After the install is complete, copy VCMOS.SYS to ?:\OS2\MDOS directory (? is the drive you installed OS/2 into).
NOTE: Please refer to PDDB Item FFZTV title APTIVA UPDATE. It has information on how to get the fix.
950124 Trap 000D with CS:EIP = 1000 : 00002eb6 on Final Reboot
- DESCRIPTION OF SYMPTOMS
- Trap on Final Reboot and every subsequent boot with above CS:EIP value.
- SUMMARY OF RESOLUTION
- Incorrect statements in CONFIG.SYS results in Trap and it is resolved by copying the generic CONFIG.SYS to the root drive.
- DETAILS OF RESOLUTION
- Follow procedure " Recovering the CONFIG.SYS File " on page 220 of Warp User's Guide to recover the original CONFIG.SYS.
950125 INSTALL PCMCIA ON IBM THINKPAD 755CD FROM WARP, UNABLE TO ACCESS THE INTERNAL IDE CDROM
DESCRIPTION OF SYMPTOMS:
IBM ThinkPad 755CD which has an IDE CDROM. User loaded the PCMCIA drivers from OS/2 WARP. Afterwarp, shutdown and reboot the system, user is unable to access the internal IDE CDROM device.
RESOLUTION:
From the problem determination, this is an IRQ conflict. Change the PCMCIA IRQ setting. To do this, add the following parameters to BASEDEV=IBM2SS01.SYS: " BASEDEV=IBM2SS01.SYS /S0=1 /C0=11 " Use IRQ 11 because it was an open IRQ. Shutdown and reboot and the user should be able to access both the PCMCIA and the internal IDE CDROM device. Note above that it is not neccessary to use IRQ 11. User should be able to find an IRQ that is available.
TITLE: 950126 ERROR " NOT ENOUGH SPACE ON HARD DISK " WITH 8590 WITH NEC CDROM CONNECTED ( SCSI I )
SYMPTOMS:
On disk #1, error msg " Not Enough Hard Disk Space to Install ... " Note: This is a CD-ROM installation. User boots up on the Installation disk and when prompt, puts in the disk #1 of the cdrom. No doublespace on the harddrive. Only DOS/Windows. FDISK did not see any "strange partitions", if it shows, this indicates that there is a "monkeys" virus.
RESOLUTION:
User has upgraded the EPROM for this 8590 and changed the NEC CDROM to set it SCSI I, since the IBM SCSI controller is SCSI I compliant.
TITLE: 950128 ADD ON DAUGHTER OR WAVE TABLE BOARDS NOT SUPPORTED UNDER OS/2 WARP 3.0
DESCRIPTION OF SYMPTOMS:
See details of resolution.
SUMMARY OF RESOLUTION:
See details of resolution.
DETAILS OF RESOLUTION:
Add on Daughter boards which enable wave table midi support are not supported under any version OS/2 including Warp 3.0.
These boards can be attached to several sound cards available on the market especially Sound Blaster cards. Users need to contact the vendor for proper OS/2 drivers if available. If a user has aquired an OS/2 driver for the Daughter board and is experiencing a problem using the device the vendor needs to be contacted for support
TITLE: 950203 THREE IDE 563 PANASONIC CDROM DRIVES WORKING UNDER OS/2 WARP
- SYMPTOMS
- Multiple cdroms connected to the same IDE adapter (SB16 card) are not recognize.
- RESOLUTION
- Creative Labs has a new driver on their BBS called CD_OS2.EXE.
BBS number is (405) 742-6660. Contact Creative Labs for more information. Note that at this point, multiple 563 Panasonic IDE CDROM drives are not supported.
