BIOS SETUP
34
•••••
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) implementation is possible only if your IDE HDD can support it and the
operating environment includes a DMA driver (Windows 95 OSR2 or a third-party IDE
bus master driver). If both your HDD and your system software can support Ultra DMA/
33(66), select “Auto” to enable BIOS support.
•
Init Display First
This item allows you to decide whether to activate either the “PCI Slot” or the “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 that the
drive can support.
•
Onboard FDD Controller
You can use this function to enable or disable the onboard FDD controller.
•••••
Onboard Serial Port 1/Port 2
Select an address and the corresponding interrupt for each of the first and second serial
ports. The Choices are: “Disabled”, “3F8/IRQ4”, “2F8/IRQ3”, “3E8/IRQ4”, “2E8/IRQ3”,
and “Auto”.
The second serial port shares resources (address and IRQ) with IrDA.
•••••
UART 2 Mode
Choose the right type of infrared device:
−−−−−
Standard: Normal operation
−−−−−
HPSIR: IrDA compliant serial infrared port
−−−−−
ASKIR: Amplitude Shift Keyed Infrared Port
