Your system may offer a variety of infrared modes on the second serial
port. The options are Standard, HPSIR or ASKIR.

IDE Prefetch Mode
The onboard IDE drive interfaces supports IDE pre-fetching for faster drive
access. If you install a primary and/or secondary add-in IDE interface
which does not support pre-fetching set this field to Disabled.

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 sup-
ports. Modes 0 through 4 provide successively increased performance. In
Auto mode, the system automatically determines the best mode for each
device.
!
Primary/Secondary, Master/Slave UDMA
Ultra DMA/66 implementation is possible only if your IDE hard drive
supports it and the operating environment includes a DMA driver (Windows
98 OSR2 or a third-party IDE bus master driver). If your hard drive and
your system software both support Ultra DMA/66, select Auto to enable
