Using Drives
The host adapter and SCSI disks are now ready for normal opera-
tion. Peripheral devices such as SCSI tape, DAT, CD-ROM, and
others require I/O Operating Environment Software driver.
When you start your system, the host adapter's BIOS performs
the necessary SCSI bus initialization procedures:
e Your system will boot from a floppy drive if a bootable
floppy diskette is inserted.
o
If no floppy is inserted, the system tries to boot from the
drive chosen as drive C, whether the drive is a non-SCSI
disk or a SCSI disk.
If two non-SCSI drives are installed, they are the only disk
drives accessible from the operating system unless:
o
You enable BIOS Support for More than 2 Drives MS-
DOS(R) 5.0 and above in the Configuration Software.
or:
You install EZ-SCSI I/O Operating Environment Software.
If one non-SCSI disk drive is installed, the AHA-1540C/1542C
BIOS allows DOS to access the non-SCSI drive as C, and the
SCSI drives as the next available drive letters.
If only SCSI disk drives are installed, AHA-1540C/1542C BIOS
