IV. BIOS SOFTWARE
Onboard FDC Controller
When enabled, this field allows you to connect your floppy disk drives to
the onboard floppy drive connector instead of a separate controller card. If
you want to use a different controller card to connect the floppy drives, set
this field to "Disabled". Default setting is "Enabled".
Onboard FDC Swap A: B:
This field reverses the drive letter assignments of your floppy disk drives.
Two options are available: "No Swap" and "Swap AB". "No Swap" is the
default setting. If you want to switch drive letter assignments, set this field
to "Swap AB", and the swap will be controlled in hardware. This works
separately from the BIOS Features floppy disk swap feature. It is function-
ally the same as physically interchanging the connectors of the floppy disk
drives.
Onboard Serial Port 1 / Onboard Serial Port 2
These fields control the assignments for the motherboard's two onboard
serial connectors. The following lists the available options:
COM1, 3F8H (Onboard Serial Port 1 default)
COM2, 2F8H (Onboard Serial Port 2 default)
COM3, 3E8H
COM4, 2E8H
Disabled (Disables the onboard serial ports)
Onboard Parallel Port
This field sets the address of the onboard parallel port connector. You can
select either: 3BCH / IRQ 7, 378H / IRQ 7 (default), 278H / IRQ 5, Dis-
abled. If you install an I/O card with a parallel port, ensure that there is no
conflict in the address assignments. The PC can support up to three parallel
ports as long as there are no conflicts for each port.
Parallel Port Mode
This field allows you to set the operation mode of the parallel port. The
default setting Normal, allows normal-speed operation but in one direction
only; EPP allows bidirectional parallel port operation at maximum speed;
ECP allows the parallel port to operate in bidirectional mode and at a speed
faster than the maximum data transfer rate; ECP+EPP allows normal speed
operation in a two-way mode.
ECP DMA Select
This selection is available only if you select ECP or ECP+EPP in the Par-
allel Port Mode. Select either DMA Channel 1, 3, or Disable. The setup
default is DMA Channel 3.
