    I have an Adaptec SCSI adapter, so I should be able to obtain this
support.  Given that the system is already running, however, the next
question is how?  Should I put on the Interrupt Enable jumper and
reinstall OS2?  That is, will OS2 automatically determinine that it
should substitute interrupt support, or do I have to tell it somehow?
    Thanks much for all the encouragement!

If the adapter was installed when OS/2 was installed, it's driver
should have been installed automatically.  You can verify this by
looking for a line in CONFIG.SYS which looks something like
BASEDEV=AHA1nnn.ADD.  

There's no way to tell the driver in CONFIG.SYS whether interrupts
are enabled, so I assume that enabling them on the card is all
that's required; no reinstallation necessary.

The README file in the root directory of the boot partition has
additional information on this subject.
