Installing Update 1 of the Adaptec 154x Series SCSI Adapter Device Driver for NEXTSTEP Release 3.2 for Intel Processors

These instructions show you how to install the Adaptec 154x series SCSI adapter device driver on an Intel-based computer running NEXTSTEPd Release 3.2. The driver is distributed in an Installer package file named Adaptec154xDriver.pkg.

Update 1 of the Adaptec 154x series SCSI adapter device driver lets you take advantage of the following SCSI adapters:

Manufacturer	Adapter	PC Bus	Notes
Adaptec	1540B	ISA
Adaptec	1542B	ISA
Adaptec	1540C	ISA
Adaptec	1542C	ISA
Adaptec	1540CF	ISA
Adaptec	1542CF	ISA
Adaptec	1740	EISA	in standard 154x mode only
Adaptec	1742	EISA	in standard 154x mode only
Bus Logic	542B	ISA
Bus Logic	747S	EISA
Bus Logic	445S	VL-Bus

The updated driver lets you use a hard disk larger than 1 gigabyte as a startup disk, if your SCSI adapter features extended BIOS translation (previously, this was only possible with the Adaptec 154xC adapter). 

The updated driver also improves support for the Adaptec 154xC and 154xCF adapters, particularly in cases where these adapters weren't always detected when starting up the computer.
