5.4. BIOS Installation of Hard Drives
SCSI hard drive installation is carried out most easily by the SCSI host adapter
BIOS when switching on the computer. The drive letters are assigned in correspondence
with the adjusted SCSI IDs starting with "Boot SCSI ID" set in the SCSI BIOS in
ascending order.
Tip: Using IDs larger than 0 (1,2 ...., etc.) for internal hard disks enables you to
boot your computer from an external drive (with ID 0) without having to open the
cabinet.
Please make sure during installation not to enter SCSI hard disks into the CMOS
set-up of the computer. The ROM installation message (during built-in check)
identifies the recognized SCSI hard disks together with the drive letters assigned to
them. In case of a non-formatted hard disk, further installation is carried out by the
programs for partitioning and formatting (for example FDISK and FORMAT) supplied
by the operating system in the usual manner; for more information about these
programs, consult your operating system manual.
Alternatively, drive partitioning can also be carried out by the program SCSIFMT
enclosed with your Dawicontrol SCSI host adapter. Furthermore, SCSIFMT offers you
the possibility of low-level formatting the hard disk, which may be necessary in the
course of the time because of reduced magnetism, variations in track positions
through mechanical wear and tear etc. Please note that not all hard disks permit low-
level formatting.
In order to further increase data throughput, you should, in accordance with your
operating system, install the respective SCSI driver, even if you only operate hard
disks.
5.5 Booting from CD
The DC-29160 U3W enables direct booting from a bootable CD without
necessary installation of a DOS driver for the CD-ROM drive. This option can be
activated or de-activated in the SCSI set-up. There are three possible formats of
bootable CDs, "no emulation", "floppy emulation" and "hard disk emulation". In order
to be able to boot from a "floppy emulation" format CD, the boot sequence in the main
board BIOS has to start with A, for instance boot sequence A,C.
