Peripherals
INTEL OnChip IDE Device
If you enter this button, it will take you a submenu with the following options:
IDE Primary / Secondary /Master / Slave PIO
The IDE PIO (Programmed Input / Output) fields let you set a PIO mode (0-4) for each
IDE devices that the onboard IDE interface supports. Modes 0 to 4 will increase
performance progressively. In Auto mode, the system automatically determines the best
mode for each device.
Options: Auto (default), Mode0, Mode1, Mode2, Mode3, Mode4.
Primary / Secondary /Master / Slave Ultra DMA
Ultra DMA functionality can be implemented if it is supported by the IDE hard drives in
your system. As well, your operating environment requires 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/100, select Auto to enable BIOS support. Options:
Auto (default), Disabled.
