AC’97 Modem
Selecting Auto will enable the AC’97 modem if it is detected onboard.
Init Display First
This item allows you to activate PCI slot or onboard display first. The choices are: PCI Slot, onboard VGA.
IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple sector read/write. If your IDE hard
drive supports block mode (most new drives do), select Enabled for automat ic detec tion of the optional
number of block read/write per sector the drive can support. The available choices are Enabled, Disabled.
Onboard FDC Controller
This feature allows you to enable or disable the onboard floppy drive controller. If you are using a floppy drive
connected to the motherboard's built-in floppy drive controller, leave it at the default setting of Enabled. But
if you are using an add-on floppy drive controller card or if you are not using any floppy drives at all, set it to
Disabled to save an IRQ. Other devices can then use the free IRQ.
Onboard Parallel Port
This feat ure allows y ou to selec t the I/O address and IRQ for the onboard parallel port. The default I/O
address of 378h and IRQ of 7 should work well in most cases. Unless you have a problem with the parallel
port, you should leave it at the default settings. The choices: 378/IRQ7, 278/IRQ5, 3BC/IRQ7, and Disabled.
ECP Mode Use DMA
When the on-board parallel port is set to ECP mode, the parallel port can use DMA3 or DMA1.
Onboard Serial Ports (1, 2, 3, 4)
This feature allows you to manually select the I/O address and IRQ for the first and second serial ports. It is
recommended that you leave it as Auto so that the BIOS can select the best settings for it. But if you need
a particular I/O port or IRQ that's been taken up by this serial port, you can manually select an alternative I/
O port or IRQ for it. You can also disable this serial port if you do not need to use it. Doing so frees up the
I/O port and IRQ used by this serial port. Those resources can then be reallocated for other devices to use.
Serial Port (3,4) Use IRQ
The choices are : IRQ 3, 4, 5, 9, 10, 11.
Serial Port 1 Mode
Select an operating mode for the serial port 1. The choices are: Standard and IRDA.
Serial Port 2 Mode
Select an operating mode for the serial port 2. The choices are: Standard, RS422, RS485, RS422 (120 ohm)
and RS485 (120 ohm).
