to Auto if you plan to use a floppy disk drive.
Serial Port A (..B)
Enabled
Disabled
Auto
Toggles the use of the onboard Serial Ports.
Enabling the ports will require system resources
such as IRQs.
Base I/O

These options are dependent on the IRQ
settings below and vice versa. They set the I/O
address for the serial ports.
Interrupt
IRQ3
IRQ4
These options are dependent on the Base I/O
settings and vice versa. They set the IRQ for the
serial ports.
Parallel Port
Enabled
Disabled
Auto
Toggles the Parallel Port. Use this port for
devices such as printers or Zip drives.
Mode
Defines the mode that the Parallel port will operate in. Leave on
default setting for most compatibility.

3.5 – PCI Configuration
Options related to PCI slot features can be altered in this section.
Primary Video
Defines which slots the system will attempt to initiate video on first.
PCI Device, Slot 1 (..2, 3,
4, 5)
Option ROM
Scan
Enables or disables device expansion ROM.
PCI Device, Slot 1 (..2, 3,
4, 5)
Enable Master

every device can operate as a PCI master.
However, PCI bus mastering allows devices that
can, to access other devices on the PCI bus
directly for increased performance.
PCI Device, Slot 1 (..2, 3,
4, 5)
Latency Timer
Defines the PCI response time delay. Certain
devices such as sound cards, which require the
most PCI access time, may benefit from a
higher latency time.
