NOTE: Neither of these options will have any affect after the disk has
been partitioned with the FDISK command. To remove partitioning, two
options are available:
• Reformat the disk using the Format Device option. See the section "De-
vice Selections Menu" below.
• Use the FDISK /MBR command at the C:\ prompt, where MBR repre-
sents master boot record.
IMPORTANT: Reformatting the disk or using FDISK /MBR erases all par-
titioning and data that exists. Be careful when using either the Format
utility or the FDISK /MBR command that you target the correct disk.
After clearing the partitions and data, it is necessary to reboot and
clear memory or the old partitioning data will be reused, thus nullifying
the previous operation.
Device Selections Menu
When you select the Device Selections option, the corresponding menu ap-
pears. The settings in this menu affect individual SCSI devices attached to the
selected integrated SCSI. Changes made from this menu do not cause the sys-
tem to reboot upon exit from the SCSI BIOS Configuration Utility. To change
a value, select the required device by using the arrow keys and press Enter. A
new menu appears providing the options and utilities available. For example,
you could cursor to Sync Rate to change the Sync Rate value of the chosen
device.
Sync Rate (Mbytes/s) – The value set with this option defines the maximum
data transfer rate the integrated SCSI attempts to negotiate. The integrated SCSI
and a SCSI device must agree to a rate they can both handle.
Width (bits) – The value set with this option defines the maximum SCSI data
width the integrated SCSI attempts to negotiate. The integrated SCSI and a
SCSI device must agree to a width they can both handle. Only host adapters
that can do 16-bit data transfers have this option enabled.
Disconnect – SCSI devices have the ability to disconnect from the initiator dur-
ing an I/O transfer. This disconnect frees the SCSI Bus to allow other I/O pro-
cesses. This option tells the integrated SCSI whether or not to allow a device to
disconnect. Some devices run faster with disconnects enabled (mostly newer
devices), while some run faster with disconnects disabled (mostly older devices).
