2.1 Introduction
The SDMS SCSI BIOS is the bootable ROM code that manages SCSI
hardware resources. It is specific to a family of LSI Logic SCSI controllers
or processors. The SDMS SCSI BIOS integrates with a standard system
BIOS, extending the standard disk service routine provided through
INT13h.
During the boot time initialization, the SCSI BIOS determines if there are
other hard disks, such as an IDE drive, already installed by the system
BIOS. If there are, the SCSI BIOS maps any SCSI drives it finds behind
the drive(s) already installed. Otherwise, the SCSI BIOS installs drives
starting with the system boot drive. In this case, the system boots from
a drive controlled by the SCSI BIOS. For version 4.05.00 and higher,
LSI Logic supports the BIOS Boot Specification (BBS).
The next section, “ Boot Initialization with BBS, ” discusses selecting boot
and drive order.
