Symptoms

  Warp installation fails on a SYS3175 (access violation exception),
  typically (but not always) around Diskette 1.


Hardware

  System board with external cache (e.g.  most of today's 386, 486,
  and Pentium system boards).


Problem

  Some system boards' external cache logic have intermittent cache
  coherency problems due to poor design.  These tend to show up
  sooner and more frequently under OS/2 because of its heavy use of
  32-bit-wide RAM access.


Workaround

  Turn off the external cache using the system board's CMOS Setup
  program and restart the installation.


Notes

  None.
