multiPort: Parallel Port Control
The parallel port may be operated in SPP (output-only), EPP (bidirectional), and ECP (extended capabilities)
modes. The mode may be selected in the BIOS, or by application software.
To configure the parallel port in the BIOS, enter the BIOS, and follow the steps below:
1. Under the “Advanced” menu in the BIOS, select the “I/O Device Configuration” submenu
2. Set the multiPort mode to “Parallel Port”
3. When a new “Parallel Port Configuration” appears, select it and configure the parallel port base address,
parallel port mode, and IRQ
multiPort: Floppy Drive
The multiPort connector can be configured as a floppy drive. To utilize the floppy controller, the multiPort mode
must be first be set to Floppy Drive in the BIOS. The complete process for setting up the multiPort as a floppy
drive is described below.
1. With the system powered off, attach a floppy drive with an adapter board to CN6.
2. Power on the system and enter the BIOS setup screen by pressing the delete key as the system boots.
3. Set Drive A to 1.44 MB in the Standard CMOS Settings section of BIOS Setup.
4. Set the multiPort to Floppy in the BIOS Setup.
5. If booting to the floppy drive is required, set the first boot device in the boot sequence to floppy drive
When the floppy drive is enabled, a special cable and adapter board is required. For more information about this
cable kit, refer to the Cable Kits and Accessories section in page 6.
AC’97 Audio
To use the CPU’s onboard audio, it must first be enabled in the BIOS. Two signaling levels are supported, so a line
out connection can be used for powered speakers, as well as a headphone connection for non-powered speakers.
Once enabled, two audio output modes can be selected:
• Line Out: This signaling level should be used for powered speakers.
• Headphone: This signaling level should be used for non-powered speakers.
Ethernet (10/100Base-T and -TX)
To use the onboard 10/100 Ethernet controller, Ethernet must first be enabled in the BIOS.
When enabled, the multi-color LED will blink to indicate an Ethernet connection. For more information, refer to
the Multi-Color LED section on page 76.
