Host Adapter BIOS—The AIC-7880 BIOS must be enabled to allow these
actions:
• Boot from a SCSI hard drive on the bus.
• Enable any of the other options listed on the same menu
(Advanced Configuration Options).
• Boot from a SCSI CD-ROM drive. If any IDE devices are selected
in the boot order, they will be chosen first over the SCSI device.
If the devices on the SCSI bus are controlled by device drivers and thus do not
need a BIOS, you can disable the option. This frees about 16 KB of memory
and shortens the boot time by up to 60 seconds. However, 2 KB of memory
space is still reserved per PCI and Plug and Play specifications.
Support Removable Disks Under BIOS as Fixed Disks (i.e., hard disks)—the
setting controls how removable-media devices are supported by the
AIC-7880 BIOS. The choices are:
Choice Description
Boot Only (default) Only the removable-media drive designated as the boot
device is treated as a fixed (hard) disk drive.
The AIC-7880 BIOS must be enabled.
All Disks All removable-media drives supported by the AIC-7880
BIOS are treated as fixed drives. (If you are a NetWare
user: all removable-media drives are automatically
supported by NetWare as fixed disks regardless of how
you set this option.)
The AIC-7880 BIOS must be enabled.
Disabled No removable-media drives running under DOS are
treated as fixed drives. Driver software is needed because
the drives are not controlled by the AIC-7880 BIOS.
CAUTION, do not remove media from drive under BIOS control
Do not remove media from a removable media drive if the drive is
under the control of the AIC-7880 BIOS.
