Floptical Drive
Support
AHA-1520A/1522A host adapters support SCSI Floppies and Flop-
tical diskette drives. This appendix discusses AHA-1520A/1522A
Floptical drive support features and provides general information
on Floptical drive characteristics.
Floptical drives are only supported by the DOS (v.3 and above) and
DOS/Windows operating systems at this time.
Floptical support is disabled by default. Refer to Jumper Block J5 on
page 2-4 to learn how to enable BIOS Support for SCSI Floptical
Drives.

Floptical Installation

Flopticals are SCSI devices and are installed in the same way as
other SCSI devices. See Connecting SCSI Devices on page 3-7.
The AHA-1520A/1522A allows you to install Floptical drives at
SCSI IDs 2, 3, 4, 5, and 6. See the Floptical manufacturer's documen-
tation for instructions on how to set the SCSI ID on your Floptical
drive.

Floptical Diskettes and The Host Adapter

The AHA-1520A/1522A BIOS supports standard 3.5-inch VHD
(Very High Density) 21 MByte Floptical diskettes, without requiring
driver software. The 3.5-inch Floptical drives also support 720 KByte
and 1.44 MByte diskettes.
The AHA-1520A/1522A host adapter supports up to four floppy
drives, including SCSI Floptical drives. You may choose your own
mix of standard floppy and Floptical drives, up to four drives.
1. AHA-1510A host adapters have no BIOS and therefore do not support
SCSI Floppies and Floptical diskette drives.
