1.2Features

This section provides a high level overview of the PCI Interface, the SCSI Interface, and Board Characteristics for the LSIU40HVD.

BIOS support for this host adapter is incorporated on the board in an 8 X 64K Flash BIOS.

1.2.1PCI Interface

The PCI interface includes these features:

•Full 32-bit DMA bus master

•Zero wait-state bus master data bursts

•Universal PCI bus voltage support

1.2.2SCSI Interface

The SCSI interface includes these features:

•Two identical isolated SCSI channels

•16-bit differential

•Automatically enabled active termination

•Two connectors per channel:

68-pin VHDCI external

68-pin, right-angle, high density internal with jack blocks

•Fast and Ultra SCSI data transfer capability

•SCSI termination power (TERMPWR) source with autoresetting circuit breaker

•SCSI Conﬁgured AutoMatically (SCAM)

•Flash Electronically Erasable Programmable Read Only Memory (EEPROM) for BIOS storage

•Serial NonVolatile Random Access Memory (NVRAM) on each channel for user conﬁguration utility and SCAM information storage

•SCSI activity LED connector for each channel
