DESCRIPTION

This document provides a list of open and closed problems related to 
OS/2 Warp on IBM systems. Temporary solutions or information for the 
problems are provided.

This list is not intended to be all-inclusive. The problems described

do not find your problem listed here, continue searching the databases 
for documents related to the symptoms you are experiencing.

RESOLUTION

Note: To contact the IBM PC BBS, call 919-517-0001.

9576/77 Systems
---------------
  H013861
  -------
  The display screen is flashing or exhibiting a "checkerboard" pattern,
  usually in yellow, but it might occur in other colors. This is caused
  by one of the following:

  * Internal Processing Error (IPE)
  * Trap Error Message
  * Kernel panic error

  The error Message displayed is:

    The System is stopped.
 
  Review the hardware configuration and remove any IRQ or DMA conflict.
  If no conflict exists and the problem continues, contact the IBM PC 
  Company Help Center (1-800-772-2227) for a driver to fix the problem.

6875/85 Systems
---------------
  H126728
  -------
  The IBM PC 700 series, 6875, and 6885 might exhibit the following
  symptoms:

  * TRAP0002.

  * System locks up while loading OS/2 2.x, OS/2 Warp from a CID
    (Configuration, Installation, and Distribution) installation.

  * System locks up when running OS/2 after a warm restart
    (Ctrl+Alt+Del).

  Install Flash BIOS update 62A or higher. The current update is
  N1JT62A.DSK and can be downloaded from the IBM PC BBS.

  H126730
  -------
  The IBM PC 700 series, 6875, and 6885 might have one or more of
  the following:

  * Intermittent system lockups
  * TRAP0002

  If the affected single in-line memory modules (SIMMs) are from
  Hyundai, replace them with FRU P/N73G3233 (4 MB) or P/N92G7521 (8 MB).
  If the affected SIMMs are not Hyundai SIMMs, continue normal problem
  determination to isolate the failing application or FRU.

  H126344
  -------
  If the cache modules in locations U31, U32, and U34 are IDT brand
  cache (the IDT logo is on the module), replace the modules in those
  locations with FRU P/N06H6052.

  H126458
  -------
  The documentation states that the 3995-A23 optical library requires
  OS/2 2/1 or higher. However, Model A23 does not operate with OS/2 
  Warp 3.0.

  H126795
  -------
  When running MS Mail or ADSM (ADSTAR Distributed Storage Manager)
  under OS/2, PCSERVER 300 (8640 Models xNx or xPx) might experience
  one of the following:

  * Intermittent TRAP0002
  * System lockup while formatting the hard disk

  A new PCI SCSI device driver for OS/2 can be downloaded from the IBM
  PC BBS. The file is IBMPSCSI.ADD, dated 02-23-95, and its size is
  49,531 bytes.

  H126799
  -------
  IBM PC 300/700 series systems, 6575, 6585, 6875, 6885, and
  PS/ValuePoint Performance Series Systems 64xx might have one of
  the following symptoms:

  * System locks up with an oversized blinking cursor in the upper-left
    corner of the screen.

  * Video synchronization is lost (distorted video) when trying to load
    the OS/2 Presentation Manager

A new version of the SVGA.EXE device driver is available for downloading
from the IBM PC BBS. The file is OS2_DACS.DSK.
