BIOS Setup
IDE Prefetch M ode
The onboard IDE drive interfaces support IDE prefetching, for faster drive
accesses. W hen you install a primary and/or secondary add-in IDE interface,
set this option to [Disabled] if the interface does not support prefetching.
Settings: [Enabled], [Disabled].
Primary/Secondary M aster/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-4)
for each of the four IDE devices that the onboard IDE interface supports. Modes
0 through 4 provide successively increased performance. In Auto mode, the
system automatically determines the best mode for each device. The settings
are: [Auto], [Mode 0], [Mode 1], [Mode 2], [Mode 3], [Mode 4].
Primary/Secondary Master/Slave UDM A
Ultra DMA/33 implementation is possible only if your IDE hard drive supports it
and the operating environment includes a DMA driver (Windows 95 OSR2 or a
third-party IDE bus master driver). If your hard drive and your system software
both support Ultra DMA/33, Ultra DMA/66 and Ultra DMA/100 select [Auto] to
enable BIOS support. The settings are: [Auto], [Disabled].

’97 (Audio Codec’97) controller will be
enabled; if not, it is disabled. Disable the controller if you want to use other
controller cards to connect an audio device. Settings: [Auto], [Disabled].
Onboard Chip SATA
This setting controls the onboard SATA controller. Settings: [SATA Disabled],
[IDE Controller], [RAID Controller], [Other Mass Storage].
