Summary Screen
—This setting controls the display of the summary
screen shown after BIOS completes its initialization, but before
booting takes place. You can disable this screen in the interest of
shortening controller boot time. The default is
Disabled
.
•
PXE Network Boot
—Setting this option to
Enabled
executes an
option ROM that allows booting a controller from the integrated
network connection through the PXE (Preboot eXecution
Environment) protocol. After setting this option, you may need to
reboot, re-enter BIOS Setup, and rearrange the items under the
Boot
menu for network booting to take precedence over floppy drives and
hard drives. The default is
Disabled
.
•
SCSI Option ROM
(VXIpc 870B only)—To boot from an SCSI
device attached to the integrated SCSI bus, set this option to
Enabled
. This results in the BIOS running the SCSI Option ROM.
Unnecessarily enabling this option results in increased boot time. You
do not need to enable this option unless you want to boot from an SCSI
device. The default is
Disabled
.
Note
Because of limited available memory for Option ROM mapping, you must enable
either PXE Network Boot or the SCSI Option ROM. Enabling both results in an
Expansion ROM
error on the next boot.
Integrated Peripherals Submenu
Use this submenu to apply nondefault configurations to the front panel
peripherals of an VXIpc 770/870B Series controller. Normally, you do not
need to modify these settings, as the factory default settings provide the
most compatible and optimal configuration possible.
•
Serial Port A & B
—This setting enables or disables COM1 and
COM2, respectively. You can also change this setting to
Enabled
and
modify the base address and Interrupt Request Level (IRQ) of a port.
The default is
Auto
, which places COM1 at 0x3F8 IRQ 4 and COM2
at 0x2F8 IRQ 3.
•
Parallel Port
—Use this setting to enable or disable LPT1. You can
also change this setting to
Enabled
and modify the base address, IRQ
level, and ISA Direct Memory Access (DMA) channel of the port. The
default is
Auto
, which places LPT1 at 0x378, IRQ 7, using ISA DMA
Channel 3 if necessary.
•
Parallel Port Mode
—The PC industry has created several different
modes of operation for this port over the years. Usually, the default
setting works for all applications. However, if a parallel port device
