1.1General Description

The LSIU80ALVD provides an Ultra2 SCSI interface to PCI computer systems. It will be referred to as the LSIU80ALVD throughout this manual. Installing this adapter in your PCI system allows connection of up to 15 SCSI devices.

The LSIU80ALVD is a 16-bit, Low Voltage Differential (LVD)/Single- Ended (SE) SCSI solution for your computer. This board can support legacy Fast SCSI and Ultra SCSI devices, and the newest LVD Ultra2 SCSI devices. It is also backwards compatible with existing wide SCSI applications for the LSI8251S and LSI8751SP/E host adapters.

The Storage Device Management System (SDMS™) software operates the board. Other SCSI software that works with the LSI53C895A PCI to Ultra2 Controller with LVDlink™ Universal Transceivers chip could also be used. BIOS support for this adapter is incorporated on the board in a Flash memory device. The LSIU80ALVD has a serial EEPROM device for storing the user’s SCSI bus configuration.

This guide, along with the PCI Storage Device Management System SDMS 4.0 User’s Guide, contains product information and installation instructions to help you gain the full benefits of the LSIU80ALVD.
