OnChip IDE Channel 0/1
The chipset contains a PCI IDE interface with support for two IDE channels.
Select Enabled to activate the primary IDE interface. Select Disabled to deac-
tivate this interface.
IDE Prefetch Mode
The onboard IDE drive interfaces supports IDE prefetching for faster drive ac-
cesses. 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 LAN Boot ROM
This field can be used to enable or disable the Boot ROM of the onboard Real-
tek 10/100 Adapter LAN Chip to support the boot up of a diskless client func-
tionality unit.
Onboard FDC 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 sys-
tem 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 correspond-
ing interrupt for the first and second serial ports.
