Parallel Mode
This field is used to specify whether the parallel port is to be used as a bi-
directional input/output port or just as an output port.
ECP
and
EPP
transfer modes
allow faster transfer rates of 2 and 2.4 Mbytes/s. These modes will only work with
peripheral devices which support them. The field Parallel must be set to
378h
or
278h
.
Printer
The port functions as an output port only (default entry).
Bidirection
Data can be transferred in both directions across the port.
EPP
Fast transfer mode (up to 2 Mbytes/s), can output and receive data.
Requires a peripheral device which supports the EPP (Enhanced
Parallel Port) transfer mode.
ECP
Fast transfer mode (up to 2.4 Mbytes/s), can output and receive
data. Requires a peripheral device which supports the ECP
(Enhanced Capability Port) transfer mode.
Diskette Controller
This field is used to enable and disable the built-in floppy disk controller on the
system board.
Enabled
The floppy disk controller is enabled - IRQ 6 is used (default
entry).

The associated interrupts (IRQ 14 for the first connector, IRQ 15 for the second
connector) will only be available if no hard disk is physically connected.
Primary
The first IDE hard disk controller is enabled (default entry). Two
IDE drives (preferably high-speed hard disks) can be attached to
the first (primary) connector. IRQ14 is occupied.
Primary And Secondary
Primary and secondary IDE drive controllers are activated (default
entry). Up to four IDE drives can be connected. Low-speed drives
are preferred for the second (secondary) connector (e.g. CD-
ROM). IRQ14 and IRQ15 are occupied.
Disabled
The IDE hard disk controller is disabled.
Mouse Controller
This field is used to enable and disable the built-in mouse controller on the system
