BIOS Setup
IDE Prefetch Mode
The onboard IDE drive interfaces support IDE prefetching, for faster drive
accesses. When you install a primary and/or secondary add-in IDE
interface, set this option to Disabled if the interface does not support
prefetching.
Primary/Secondary Master/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 Ultra DMA
Ultra DMA 33/66/100/133 implementation is possible only if your IDE
hard drive supports it and the operating environment includes a DMA
driver (Windows ME, XP or a third-party IDE bus master driver). If your
hard drive and your system software both support Ultra DMA/33, Ultra
DMA/66, Ultra DMA/100 and Ultra DMA/133, select Auto to enable BIOS
support. Settings: Auto, Disabled.
IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple
sector read/write. If your IDE hard drive supports block mode (most new
drives do), select Enabled for automatic detection of the optimal number
of block read/write per sector the drive can support. Setting options:
Disabled, Enabled.

AC97 Audio
Auto allows the motherboard’s BIOS to detect whether you’re using any
audio device. If so, the onboard audio controller will be enabled. If not,
the onboard audio controller will be disabled. If you want to use different
