Secondary Slave PIO
Auto
Mode 0
Mode 1
Mode 2
Mode 3
Mode 4
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 Master UDMA
Primary Slave UDMA
Secondary Master UDMA
Secondary Slave UDMA
Auto
Disabled
UDMA (Ultra DMA) is a DMA data transfer protocol
that utilizes ATA commands and the ATA bus to allow
DMA commands to transfer data at a maximum burst
rate of 33 MB/s. When you select
Auto
in the four IDE
UDMA fields (for each of up to four IDE devices that
the internal PCI IDE interface supports), the system
automatically determines the optimal data transfer
rate for each IDE device.
Init Display First
AGP
PCI Slot
This tells the BIOS where to look first for the display
adaptor. This should be set by default to AGP unless
you fit a secondary PCI card or completely disable the
onboard video adapter.
IDE HDD Block Mode
Enabled
Disabled
If your IDE HDD supports block mode, select Enabled
for automatic selection of the optimal number of block
read/writes per sector the drive can support.
Onboard Lan Boot ROM
Enabled
Disabled
Activates or deactivates the LAN boot ROM (if fitted)
Onboard FDD Controller
Enabled
Disabled
This should be enabled if your system has a floppy
disk drive (FDD) installed. If the floppy drive is
removed, you will need to disable this feature.
Onboard Serial Port 1
Disabled
3F8/IRQ4
2F8/IRQ3
3E8/IRQ4
2E8/IRQ3
AUTO
This item allows you to determine the access onboard
serial port 1/port 2 controllers have with which IRQ
and I/O address.
Onboard Serial Port 2
Disabled
3F8/IRQ4
2F8/IRQ3
3E8/IRQ4
2E8/IRQ3
AUTO
This item allows you to determine the access onboard
serial port 1/port 2 controllers have with which IRQ
and I/O address.
UART 2 Mode
Standard
HPSIR
ASKIR
Reserved Function
Do Not Alter
Onboard Parallel Port
Disabled
3BC/IRQ7
378/IRQ7
278/IRQ5
This item allows you to determine access to the
onboard parallel port controller with which IRQ and I/O
address.
Onboard Parallel Mode
Normal
EPP
ECP
ECP/EPP
Selects the mode for the onboard parallel port.
Standard Parallel Port (SPP), Normal EPP (Extended
Parallel Port), and ECP (Extended Capabilities Port)
ECP+EPP.
Select Normal unless you are certain your hardware
and software both support EPP or ECP mode.
