Installation of Warp fails with SYS3175 typically around diskette

Last Updated: 5th December, 1994

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.
