SuperPCK with Coretest

Description:

Coretest is a public domain application that comes in many
different versions. It runs various benchmark tests on a system.

Some of the Taiwanese computer manufacturers rely on Coretest
for their production quality assurance. Multisoft and the
Digital Research engineering labs are working on a problem
reported from Taiwan.

If SuperPCK is running in extended memory, Coretest causes the
cache to get corrupted and Diskopt reports cross-linked files.
Actual data on the drive is not lost or corrupted. Rebooting
corrects the error.

Workaround to avoid any problems is:

1. Run SuperPCK in expanded memory, or

2. Set the switch /B- which decreases interrupt timeout.

This problem is expected to be fixed in the near future.
