Features

Fast Data Transfer

■10 MBytes/second synchronous Fast SCSI data rate
■5 MBytes/second synchronous SCSI data rate
■3 MBytes/second data rate on the ISA bus, the highest speed
allowed in the Programmed I/O (PIO) environment)
■2 MBytes/second asynchronous SCSI data rate

Superior Price/Performance Value

■High speed PIO data transfer
■Optional high speed DMA data transfer (supported under
OS/2 on EISA-bus computers)
■Minimal SCSI overhead in single-tasking environments when
utilizing disconnect/reconnect capabilities
■16-bit host bus data transfer widths

Multitasking

■Each host adapter supports up to eight simultaneous I/O tasks
when utilizing SCSI-2 Disconnect/Reconnect feature.

Connectivity

■Each host adapter supports up to seven SCSI devices and up to
eight logical units (LUNs) per SCSI device.
■Full SCSI Floppy/Floptical® (21 MByte) diskette supports con-
figurations of up to four floppy-type diskettes (up to two stan-
dard floppy diskettes).
■Supports both synchronous and asynchronous devices: dis k
drives, tape, CD-ROM, WORM, DAT, etc.

Compatibility

■SCSI BIOS with boot capability and support for up t o two hard
disk drives under DOS (AHA-1520A/1522A only)
■Supports SCSI hard disks with capacities abo ve 1 GByte
