Adaptec AHA-1740A - Manual (Page 55)

Appendix B
Loading the I/O Operating
Environment Software
DOS/Windows
Under DOS 5.0 or higher, up to seven SCSI fixed disk drives can
be connected to the 1740A/1742A/1744 without additional soft-
ware. (Older versions of DOS support up to two disk drives).
The host adapter treats removable media drives as fixed disk
drives provided you enable Treat Removable Disks Under BIOS
as Fixed Disks in Advanced Configuration Options, and do not re-
move the media while your computer power is on.
Additional software is required if you desire to do the following:
•
Treat removable media devices as removable while your
computer is running.
•
Support more than two fixed disk drives under versions of
DOS prior to MS-DOS 5.0.
•
Use devices other than fixed disk drives such as SCSI
tape, CD-ROM, scanners, etc.
Refer to the documentation received with your operating environ-
ment software package for instructions on loading your SCSI I/O
Operating Environment for versions of DOS prior to MS-DOS 5.0
