BIOS
Page 4-12
On-Chip Cnannel 0/1
The integrated peripheral controller contains an IDE interface with support for two
IDE channels. Select Enabled (default) to activate each channel separately.
Options: Enabled, Disabled.
IDE 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 default is Auto.
Options: Auto, Mode 0 ~ 4.
IDE Primary/Secondary Master/Slave UDMA
This allows you to select the mode of operation for the Ultra DMA-33/66/100/133
implementation is possible only if your IDE hard drive supports it and the operating
environment includes a DMA driver. If your hard drive and your system software
both support Ultra DMA-33/66/100/133, select Auto to enable UDMA mode by
BIOS or you can select mode by manual.
Options: Auto, Disabled.
IDE Prefetch Mode
Selecting Enabled reduces latency between each drive read/write cycle, but may
cause instability in IDE subsystems that cannot support such fast performance. If
you are getting disk drive errors, try setting this value to Disabled. This field does
not appear when the Internal PCI/IDE field, above, is Disabled.
Options: Enabled, Disabled.
Sil3112 Serial ATA (Optional)
This item enables the onboard Sil3112 serial ATA feature.
Options: Enabled, Disabled.
Init Display First
If two video cards are used (1 AGP and 1 PCI) this specifies which one will be the
primary display adapter.
Options: PCI Slot, Onboard/AGP.
Onchip USB
Enables the USB controllers.
Options: Disabled, V1.1+V2.0, V1.1.
