OnChip IDE Primary/Secondary
The integrated peripheral controller contains an IDE interface with support for two IDE
channels. Select Enabled to activate each channel separately. The settings are: Enabled and
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 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 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.
