4Software Support
DOS/Windows
When you are using AHA-1520A/1522A host adapters under DOS,
you can connect up to two SCSI hard disk drives per host adapter
without additional software. AH A-1510A host adapters always
need additional device drivers because they have no onboard BIOS.
You need additional software if you want to do any of the following
with your AHA-1520A/1522A host adapter:
■Support more than two SCSI hard disk drives
■Remove or switch removable media (for example, Bernoulli
cartridges) while your computer is running
■Support CD-ROM drives
■Support devices other than CD-ROM drives and disk drives –
for example, SCSI tape drives, scanners, plotters, or WORM
drives
■Disable the BIOS on the AHA-1520A/1522A host adapter
