OnChip IDE Device:
Press [
Enter
] to enter the sub-menu, which contains the following items for
advanced control:
1.
On-Chip Primary/Secondary PCI IDE:
You can set this to disable the On-Chip IDE controller if you are going to add a
higher performance IDE board
2.
IDE 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.
3.
IDE 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.
4.
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, select Enabled to
auto-detect the optimal number of block read/writes per sector the drive can
