UART Mode Select Normal

IDE HDD Block Mode
This field allows your hard disk controller to use the fast block mode to
transfer data to and from your hard disk drive.
Init Display First
The default setting is PCI Card .
IDE DMA Transfer Access
This field, by default, is enabled
IDE Primary/Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster.
Rather than have the BIOS issue a series of commands that transfer to or
from the disk drive, PIO (Programmed Input/Output) allows the BIOS to
communicate with the controller and CPU directly.
The system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing.
Primary/Secondary Master/Slave UltraUDMA
These fields allow your system to improve disk I/O throughput to
33Mb/sec with the Ultra DMA/33 feature.
Onboard FDC Controller
Select Enabled if your system has a floppy disk controller (FDC)
installed on the motherboard and you wish to use it. If you install an
add-in FDC or the system has no floppy drive, select Disabled in this
field. This option allows you to select the onboard FDD port.
Onboard Serial Port
These fields allow you to select the onboard serial ports and their
addresses. The default values for these ports are:
Serial Port 1 3F8/IRQ4
Serial Port 2 2F8/IRQ3
