IDE 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 enhanced performance.
In Auto mode, the system automatically determines the best mode for
each device.
IDE Primary/Secondary Master/Slave UDMA
Ultra DMA/33/66 implementation is possible only if your IDE hard drive
supports it and the operating environment includes a DMA driver (Windows
95 OSR2 or a third-party IDE bus master driver). If your hard drive and
your system software both support Ultra DMA/33/66, select Auto to enable
BIOS support.
The Choice: Auto, Disabled
Init Display First
This item allows you to decide to active PCI Slot or AGP first
The choice: PCI Slot, AGP.
IDE HDD Block Mode
This allows your hard disk controller to use the fast block mode to transfer
data to and from your hard disk drive (HDD).
Enabled
IDE controller uses block mode.
Disabled
IDE controller uses standard mode.
Onboard FDD Controller
This should be enabled if your system has a floppy disk drive (FDD)
installed on the system board and you wish to use it. Even when so
equipped, if you add a higher performance controller, you will need to
disable this feature.
The Choice: Enabled, Disabled.
Onboard Serial Port 1/Port 2
This item allows you to determine access onboard serial port 1/port 2
controller with which I/O address.
The choice: 3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4, 2E8/IRQ3, Disabled, Auto.
