Start-up Sequences
Introduction
This chapter describes the DAC960PG start-up procedures and messages
produced by the BIOS during start-up or re-boot. This chapter also explains
three BIOS options to be considered: BIOS enable/disable, CD-ROM boot
enable/disable, and a 2 or 8 Gigabyte Disk Drive Geometry setting.
The DAC960PG BIOS provides a single threaded interface to access up to
eight logical units (system drives) on each controller.
The Firmware 4.x BIOS presents physical drives to the host as large disk
drives with either 2 MB per cylinder or with 8 MB per cylinder. An
allowable number of up to 1024 cylinders allows a physical drive of up to
8GB to be accessed through the BIOS. An operating system specific driver is
required to access data beyond this limit.
Refer to the documentation for the DAC960 Software Kit for more
information on installing and using the various network operating system
drivers with the DAC960PG.
Instructions on using the DOS driver and creating a DOS-bootable disk are
located in the DACCF Configuration & Utilities diskette DOS subdirectory
in the file README.TXT.
System Power-Up Sequence
If the SCSI drives are powered up separately from the system, you should
always power up the SCSI drives before the host system. The drives and the
host system can power up simultaneously, as they would when there is a
common power switch for both.
BIOS Start-up Sequence
When invoked during power up, the BIOS will display a sign-on message
with its version number and date. The sign-on message looks similar to the
following:
