C. Primary/Secondary/Master/Slave UltraDMA
UDMA (Ultra DMA) is a DMA data transfer protocol that utilizes ATA commands
and the ATA bus to allow DMA commands to transfer data at a maximum burst
rate of 66 MB/s. When you select Auto in the four IDE UDMA fields (for each
of up to four IDE devices that the internal PCI IDE interface supports), the system
automatically determines the optimal data transfer rate for each IDE device.
D. IDE Burst Mode
Selecting Enabled reduces latency between each drive read/write cycle, but may
cause instability in IDE subsystems that cannot support such fast performance. If
you are getting disk drive errors, try setting this value to Disabled. This field does
not appear when the Internal PCI/IDE field is Disabled.
E. 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 drivesdo),
select Enabled for automatic detection of the optimal number of block read/writes
per sector the drive can support.
F. Onboard FDC Controller
Select Enabled if your system has a floppy disk controller (FDC) installed on the
system board 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.
G. Onboard Serial Port 1 and 2
Select a logical COM port name and matching address for the first and second
serial ports. Select an address and corresponding interrupt for the first and second
serial ports.
H. IR Address Select
This function allows user to select the IR address/IR mode and IR IRQ.
I. Onboard Parallel Port
Select a logical LPT port address and corresponding interrupt for the physical
parallel port.
J. Parallel Port Mode
Select an operating mode for the onboard parallel (printer) port. Select Normal,
Compatible, or SPP unless you are certain your hardware and software support one
of the other available modes.
