VIA 82C694 ATX Mainboard
AWARD BIOS SETUP
4-12
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.
Onboard Serial Port 1/Port 2
These two selection fileds allow you to select the I/O address and corresponding
interrupt for the first and second serial ports.
UART 2 Mode
This item allows you to select which mode for the Onboard Serial Port 2.
