Onchip IDE First Channel
Onchip IDE Second Channel
You can use this item to enable or disable the primary and secondary IDE channels that are
built into this mainboard. When one or both channels are enabled (the default value is Both)
items appear which allow you to set the PIO (programmable input/output) mode and the
UltraDMA mode for master and slave devices on the channels. We recommend that you
leave these items at the default value Auto. The system will then automatically use the best
performance PIO mode and UltraDMA mode for each device.
IDE Prefetch Mode
The built-in IDE drive interfaces support IDE prefetching for faster drive accesses. If you
use an aletenative IDE interface (on an expansion card, disable this field if the alternate
IDE interface does not support prefetching.
IDE HDD Block Mode
IDE hard disks can deliver better performance if they use block mode transfer. Most
modern hard disk drives support block mode transfers so this item is Enabled as a default.
IDE Primary Master PIO
IDE Primary Slave PIO
IDE Secondary Master PIO
IDE Secondary Slave PIO
Each IDE channel supports a master device and a slave device. These four items let you
assign which kind of PIO (Programmed Input/Output) is used by IDE devices. You can
choose Auto, to let the system auto detect which PIO mode is best, or you can install a PIO
mode from 0-4.
IDE Primary Master UDMA
IDE Primary Slave UDMA
IDE Secondary Master UDMA
IDE Secondary Slave UDMA
Each IDE channel supports a master device and a slave device. This motherboard supports
UltraDMA. UltraDMA technology provides faster access to IDE devices. If you install a
device which supports UltraDMA, change the appropriate item on this list to Auto. You
may have to install the UltraDMA driver supplied with this motherboard in order to use an
UltraDMA device.
Init Display First
Use this item to define if your graphics adapter is installed in one of the PCI slots, or if you
have installed an AGP graphics adapter into the AGP slot.
Onboard FDC Controller
This item enables or disables the floppy diskette drive controller built into this mainboard.
Onboard Serial Port 1
This item lets you disable the built-in serial port 1, or enable it by assigning an I/O address
and an Interrupt Request Line (IRQ).
Onboard Serial Port 2
This item lets you disable the built-in serial port 2, or enable it by assigning an I/O address
and an Interrupt Request Line (IRQ).
