IDE Master LBA Mode
This parameter enables Logical Block Addressing (LBA) mode for master hard disks
connected to the IDE controller. LBA mode translates the physical parameters of the hard
disk to logical parameters, permitting the use of disk space beyond 528 MB.
IDE Slave LBA Mode
This parameter enables LBA mode for slave hard disks connected to the IDE controller. LBA
mode translates the physical parameters of the hard disk to logical parameters, permitting the
use of disk space beyond 528 MB.
Chipset
Chipset contains the parameters that affect the functionality of some hardware components.
Sound Controller
This parameter enables or disables the sound processor circuitry on the system board. The
default is Enabled.
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 system are PCI-based, this
option is set to Disabled by default.
PCI Video Frame Buffer
The PCI Video Frame Buffer parameter allows you to implement the read prefetch support in
the linear buffer of the system graphics hardware. System performance increases when set to
Enabled (the default).
NOTE If you install a graphics card that does not support read prefetch, you must set this parameter
to Disabled for proper display.
PCI Frame Buffer USWC Mode
When enabled, this parameter removes from the buffer polygon data that otherwise would be
obscured by other polygons. This reduction in the amount of data written to the display
improves video performance by reducing the time required to update the display.
