1.1 General Description
The LSI20860 provides a low-cost SCSI solution for attaching SCSI
devices (disk drives, scanners, CD-ROM drivers, tape drives, removable
media drives, etc.) to PCI computer systems with an ISA/EISA bracket
type. The LSI20860 uses the LSI53C860 PCI to Ultra SCSI I/O
Processor chip, an 80 MHz oscillator, and transfers SCSI data up to
20 Mbytes/s.
