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 UDMA
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 and
Ultra DMA/66, select Auto to enable BIOS support. The settings are: Auto, Disabled.
IDE Prefatch
The selection is for you to set the IDE device as the first priority to activate.
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/writes per sector the drive can support. The settings are: Enabled,
Disabled.
Delay for HDD (Secs)
The selection is set for you to extend the time to search for the HDD which needs more time
to activate.
