3-4 Integrated Peripherals
This section provides information on setting peripheral devices. By choosing the
Integrated Peripherals option from the CMOS Setup Utility menu (Figure 3-1), the
screen below is displayed. This sample screen contains the manufacturer's default
values for the motherboard.
Figure 3-5 Integrated Peripherals Screen
VIA OnChip IDE Device:
Press [
Enter
] to enter the sub-menu, which contains the following items for advanced
control:
1.
On-Chip Primary IDE Channel 0/1:
You can set this to disable the On Chip IDE controller if you are going to add an
extra higher performance IDE board.
2.
IDE Prefetch Mode:
The onboard IDE drive interfaces support s prefetching, for faster drive accesses. Set
to [
Disabled
] if this primary or secondary.
3.
Primary/Secondary Master/Slave PIO:
The four IDE PIO (programmed Input/Output) fields let you set a PIO mode (0-4)
for each IDE device that the internal PCI IDE interface supports. Modes 0 through 4
provide successively increased performance. In Auto mode, the system automatically
determines the best mode for each device.
4.
Primary/Secondary Master/Slave UDMA:
Ultra DMA implementation is possible only if your IDE device supports it and your
operating environment contains a DMA driver. If both your hard drive and software
support Ultra DMA, select [
Auto
] to enable BIOS support.
