BIOS SETUP
Onboard FDC Controller
Select Enabled if your system has a floppy disk controller (FDC)
installed on the board and you wish to use it. If you install an add-in
FDC or the system has no floppy drive, select Disabled in this field.
Onboard Serial Port
These fields allow you to select the onboard serial and parallel ports
and their address. The default values for these ports are:
Serial Port 1 3F8/IRQ4
Serial Port 2 2F8/IRQ3
Serial Port 3 3E8h/IRQ11
Serial Port 4 2E8h/IRQ10
UART Mode Select
This field determines the UART 2 mode in your computer. The default
value is Normal. Other options include IrDA and ASKIR.
Watch Dog Timer Select
The options available include 2 Min,10 Min,30 Min,1 Hour,2 Hour,
3 Hour,4 Hour and Disabled. By default, this field is set to Disabled.
IDE DMA Transfer Access
Allows IDE transfer to be done in DMA mode. By default, this field is
set to Enabled.
IDE Prefetch Mode
The default setting is Disabled.
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.
