Parallel Port Mode (ECP+EPP)
This field allows you to set the operation mode of the parallel port. The
setting ECP+EPP allows normal speed operation in a two-way mode;
Normal allows normal-speed operation but in one direction only; EPP
allows bidirectional parallel port operation at maximum speed; and ECP
allows the parallel port to operate in bidirectional mode and at a speed
faster than the maximum data transfer rate.
ECP DMA Select (3)
This selection is available only if you select ECP or ECP+EPP in the
Parallel Port Mode. Select either DMA Channel 3, Disabled, or 1.
Onboard PCI IDE Enable (Both)
You can enable the Primary IDE channel, Secondary IDE channel, or
Both, or Disable both channels (for systems with only SCSI drives).
IDE Ultra DMA Mode (Auto)
This sets the IDE UltraDMA to be active when using UltraDMA-capable
IDE devices. The BIOS will automatically adjust or disable this setting
for slower IDE devices so that Auto or high settings will not cause
problems for older IDE devices. Choose Disable if you do not want this
feature for all devices.
IDE 0 Master/Slave PIO/DMA Mode, IDE 1 Master/Slave PIO/DMA
Mode (Auto)
Each channel (0 and 1) has both a master and a slave making four IDE
devices possible. Because each IDE device may have a different Mode
timing (0, 1, 2, 3, 4), it is necessary for these to be independent. PIO and
DMA timings can be independently set. The default setting of Auto will
allow autodetection to ensure optimal performance.
