For years I had been using my SyQuest SCSI cartridge drive as
a fixed drive under BIOS control without apparent problems.
This meant the cartridge was not removable without rebooting,
but saved the 1st meg memory requred for the SCSI ASPI manager
and SyQuest driver:

  D0F9:0000 | SCSIMGR$ | 5E00h, 24,064 | DEVICE = installed device driver
  D6DA:0000 | SYQ55SYS | 1DB0h,  7,600 | DEVICE = installed device driver

Every configuration scheme I tried worked and worked well, but
at some point I'd encounter the occasional problem.  Best
described as flow control with the drive being a just little
out of control.  For example I could backup an entire drive to
the cartridge with Fastback Express, but not TAR which would
work ok backing up about 1/2 the drive.

In addition to the above driver defaults: I had to configure
the SCSI host adapter back to the default of not to putting
non-boot removable drives under BIOS control and make sure the
cartridge was formatted by the SyQuest utility.
