SIS OnChip IDE Device
If you highlight the literal “Press Enter” next to the “SIS
OnChip IDE Device
” label and
then press the enter key, it will take you a submenu with the following options:
Internal PCI/IDE
This item allows you select Internal PCI/IDE.
The Choices: Both
(default), Disabled, Primary, Secondary.
IDE Primary / Secondary Master / Slave PIO
The IDE PIO (Programmed Input / Output) fields let you set a PIO mode (0-4)
for each of the 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 Choices: Auto
(default), Mode0, Mode1, Mode2, Mode3, Mode4.
Primary / Secondary Master / Slave UltraUDMA
Ultra DMA/133 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/133, select Auto to
enable BIOS support.
The Choices: Auto
(default), Disabled.
