manually to a lower mode, e.g., from Mode 3 to Mode 2. All IDE
drives should work with PIO mode 0. There are six options:
•
Auto (default)
•
Mode 0
•
Mode 1
•
Mode 2
•
Mode 3
•
Mode 4
IDE Primary/Secondary Master/Slave UDMA: When set to
“Auto” the BIOS will automatically load the Ultra DMA 33 driver to
match the transfer rate of IDE hard disk drives that support Ultra
DMA 33 mode. The options are “Auto” (default) and “Disabled.”
Init Display First: This item sets whether the PCI Slot or AGP is ac-
tivated first. The options are “PCI Slot” (default) and “AGP”.
IDE HDD Block Mode: Enable this field if your IDE hard drive
supports block mode. Block mode enables BIOS to automatically de-
tect the optimal number of block read and writes per sector that the
drive can support. The default s etting is “Enabled.”
Onboard FDD Controller: This option enables the onboard floppy
disk drive controller. The default setting is “Enabled.”
Onboard Serial Port 1/2: These options are used to assign the I/O
addresses for the two onboard serial ports. They can be assigned as
follows:
•
Disabled (disables the onboard serial port)
•
3F8/ IRQ4
•
2F8/ IRQ3
•
3E8/ IRQ4
•
2E8/ IRQ3
•
Auto (default)
UART 2 Mode Select: Enables you to select the infrared communi-
cation protocol—Standard (default), IrDA, or ASKIR. IrDA is
Hewlett Packard’s infrared communication protocol with a maximum
baud rate up to 115.2K bps. ASKIR is Sharp’s infrared communica-
tion protocol with a maximum baud rate up to 57.6K bps.
