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
