Onboard FDC Controller
Select Enabled if your system has a floppy disk controller (FDD) installed on the system board and
you wish to use it. If you install add-on FDC or the system has no floppy drive, select Disabled in this
field. The settings are: Enabled and Disabled.
Onboard Serial Port 1/Port 2
Select an address and corresponding interrupt for the first and the second serial ports. The settings
are: 3F8/IRQ4, 2E8/IRQ3, 3E8/IRQ4, 2F8/IRQ3, Disabled, Auto.
UART Mode Select
This item allows you to determine which InfraRed(IR) function of the onboard I/O chip, this functions
uses.
Onboard Parallel Port
There is a built-in parallel port on the on-board Super I/O chipset that Provides Standard, ECP, and
EPP features. It has the following option:
Disabled
(3BCH/IRQ7)/
Line Printer port 0
(278H/IRQ5)/
Line Printer port 2
(378H/IRQ7)
Line Printer port 1
Parallel Port Mode
SPP
: Standard Parallel Port
EPP
: Enhanced Parallel Port
ECP
: Extended Capability Port
SPP/EPP/ECP/ECP+EPP
To operate the onboard parallel port as Standard Parallel Port only, choose “SPP.” To operate the
onboard parallel port in the EPP modes simultaneously, choose “EPP.” By choosing “ECP”, the
onboard parallel port will operate in ECP mode only. Choosing “ECP+EPP” will allow the
onboard parallel port to support both the ECP and EPP modes simultaneously. The ECP mode
has to use the DMA channel, so choose the onboard parallel port with the ECP feature. After
selecting it, the following message will appear: “ECP Mode Use DMA” at this time, the user can
choose between DMA channels 3 to 1. The onboard parallel port is EPP Spec. compliant, so
after the user chooses the onboard parallel port with the EPP function, the following message will
be displayed on the screen: “EPP Mode Select.” At this time either EPP 1.7 spec. or EPP 1.9
spec. can be chosen.
