Sound, 8-bit DMA Select 

-- This parameter allows you to select the 8-bit

DMA used by the sound subsystem.  The default is DMA1.  The other

choice is DMA3.

Sound, 16-bit DMA Select

-- This parameter allows you to select the

16-bit DMA used by the sound subsystem.  The default is DMA5.  The other

choice is DMA7.

Sound, IRQ Select 

-- This parameter allows you to select the IRQ used by

the sound subsystem.  The default is IRQ10.  Other choices are IRQ5 and

IRQ7.

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.
