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.
