B w w w w Floptical Drive Support AHA-1520A/1522A host adapters support SCSI Floppies and Floptical diskette drives. This appendix discusses AHA-1520A/1522A1 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 documentation 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.
