- Here's an update. Someone suggested that the Future Domain 8-bit cards don't
- allow interrupts and this could be the reason why this was happening. I would
- have happily gone out and bought a new card because of this, except for one
- thing. Under Windows 3.1, I can access the Rodime, use the mouse, AND use
- my modem at the same time without any noticeable penalty in performance and
- definitely no mouse jerkiness. So it couldn't be the interrupt thing...could
- it?
-
- Any help or advice is appreciated. BTW- in case it makes a difference, I am
- using the FD8XX.ADD driver that shipped with OS/2 for the FD SCSI.
-
- Thanks
