3.6 INTEGRATED PERIPHERALS
This option sets your hard disk configuration, mode and port.
IDE Primary/Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster. Rather than have the BIOS issue a series of
commands that transfer to or from the disk drive, PIO (Programmed Input/Output) allows the BIOS to
communicate with the controller and CPU directly.
The system supports five modes, numbered from 0 (default) to 4, which primarily differ in timing. When Auto is
selected, the BIOS will select the best available mode.
IDE Primary/Secondary Master/Slave UDMA
These fields allow your system to improve disk I/O throughput to 33Mb/sec with the Ultra DMA/33 feature. The
options are Auto and Disabled.
On-Chip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with support for two IDE channels. Select Enabled
to activate each channel separately.
USB Keyboard Support
Select Enabled if your system contains a Universal Serial Bus (USB) controller and you have a USB keyboard.
Onboard Serial/Parallel Port
These fields allow you to select the onboard serial and parallel ports and their addresses. The default values for
these ports are:
Serial Port 1 3F8/IRQ4
Serial Port 2 2F8/IRQ3
Parallel Port 378H/IRQ7
Serial Port 3 3E8/IRQ5
UART Mode Select
This field determines the UART mode in your computer. The settings are Normal, IrDA and ASKIR. The default
value is Normal.
Parallel Port Mode
This field allows you to determine parallel port mode function.
SPP Normal Printer Port
EPP Enhanced Parallel Port
ECP Extended Capabilities Port
