IDE Prefetch Mode
The onboard IDE drive interfaces supports IDE prefetching for faster drive accesses. If
you install a primary and/or secondary add-in IDE interface, set this field to disabled if the
interface does not support prefetching.
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.
Primary/Secondary, Master/Slave UDMA
Ultra DMA/66 implementation is possible only if your IDE hard drive supports it and the
operating environment includes a DMA driver (Windows 98 OSR2 or a third-party IDE bus
master driver). If your hard drive and your system software both support Ultra DMA/66,
select Auto to enable BIOS support.
Init Display First
This field allows you to decide to active whether PCI Slot of VGA card or AGP first.
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 (most new drives do), select Enabled for
automatic detection of the optimal number of block read/writes per sector the drive can
support.
Onboard FDD Controller
Select Enabled if your system has a floppy disk controller (FDC) installed on the system
board and you want to use it. If you install add-in FDC or the system has no floppy drive,
select Disabled in this field.
