86 Chapter 7 - Using AMIBIOS Setup
PCI VGA Buffering
-- The PCI VGA Buffering parameter allows you to
implement the read prefetch support in the linear buffer of the workstation
graphics hardware. System performance increases when set to Enabled
(default). If you install a graphics card that does not support read prefetch,
this parameter must be set to Disabled for proper display.
PCI VGA Palette Snooping
-- This parameter allows palette data from an
installed PCI graphics board to be shared with an installed ISA graphics
board. Since the graphics delivered with the workstation are PCI-based, this
option is set to Disabled by default.
Primary PCI SCSI
-- This parameter activates the PCI-based SCSI
controller on the system board when set to Enabled (default). The SCSI
controllers can be disabled by changing the value to Disabled.
Secondary PCI SCSI
-- This parameter activates the PCI-based SCSI
controller on the riser card when set to Enabled (default). The SCSI
controllers can be disabled by changing the value to Disabled.
Operating System Boot Device
-- This parameter specifies which
controller the BIOS will attempt to boot from first. The device that you
specify to be the boot device will be assigned to drive C. By default, drive C
is the system hard disk drive. Refer also to the System Boot Up Sequence
parameter in “Advanced Setup.”
Boot to PnP Operating System
-- When this parameter is set to No
(default), the BIOS will initialize all devices during boot up. When set to
Yes, the BIOS only performs the amount of initialization required to load the
operating system. Any other device initialization must then be performed by
the operating system.
Installed Memory Speed
-- The workstations use 70 ns memory SIMMs,
so this parameter is set to 70 ns by default. The other choice is 60 ns, which
should not be used. The system will not boot if you set this parameter to 60
ns.
Peripheral Setup
The Peripheral Setup menu has parameters that affect option boards, serial
ports, and parallel port functionality.
