4. BIOS SETUP

Onboard AC97 Modem Controller, Audio Controller [Auto]

[Auto] allows the motherboard’s BIOS to detect whether you are using any modem/
audio device. If a modem/audio device is detected, the onboard modem/audio con-
troller will be enabled; if no modem/audio device is detected, the onboard modem/
audio controller will be disabled. If you have conflicts with the onboard modem/
audio controller, you may set the appropriate field to [Disabled]. Configuration op-
tions: [Disabled] [Auto]

Onboard FDC Swap A & B [No Swap]

This field allows you to reverse the hardware drive letter assignments of your floppy
disk drives. Configuration options: [No Swap] [Swap AB]

Floppy Disk Access Control [R/W]

When set to [Read Only], this field protects files from being copied to floppy disks
by allowing reads from the floppy disk drive but not writes. The setup default [R/W]
allows both reads and writes. Configuration options: [R/W] [Read Only]

Onboard Serial Port 1 [3F8H/IRQ4], Onboard Serial Port 2 [2F8H/IRQ3]

These fields allow you to set the addresses for the onboard serial connectors. Serial
Port 1 and Serial Port 2 must have different addresses. Configuration options: [3F8H/
IRQ4] [2F8H/IRQ3] [3E8H/IRQ4] [2E8H/IRQ10] [Disabled]
