On-Chip 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 deactivate this inter-
face
.
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 33/66/100 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 sup-
port Ultra DMA 33/66/100, 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 En-
abled 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 sys-
tem 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 fields allow you to select the I/O address and corresponding in-
terrupt for the first and second serial ports.
