1.1 General Description
LSI Logic’s Symbios™ SYM22801 Dual Channel PCI to Ultra SCSI host
adapter provides a SCSI-3, Ultra SCSI interface to PCI computer
systems. Installing this adapter in your PCI system allows connection of
SCSI devices over a SCSI bus.
The dual channel SYM22801 board provides 16-bit, Single-Ended (SE),
SCSI solutions for your computer, using only one PCI slot. This board
supports legacy Fast SCSI devices, and the newest Ultra SCSI devices.
It is also backwards compatible with the existing SYM8751SP host
adapter but with a different external connector.
Symbios SCSI Device Management System (SDMS™) software
operates the board, but the design of the board does not prevent other
software from being written and used with it. BIOS support for this host
adapter is incorporated on the board in an 8 X 64K Flash BIOS.
This guide and the PCI SCSI Device Management System SDMS 4.0
User’s Guide contain product information and installation instructions to
help you gain the full benefits of the SYM22801 Dual Channel PCI to
Ultra SCSI host adapter for your computer system.
