ASUS P3B-1394 User’s Manual 53
Onboard Parallel Port (378H/IRQ7)
This field sets the address of the onboard parallel port connector. You can select
3BCH/IRQ 7, 378H/IRQ 7, 278H/IRQ 5, or Disabled. If you install an I/O card with
a parallel port, ensure that there is no conflict in the address assignments. The PC
can support up to three parallel ports as long as there are no conflicts for each port.
Parallel Port Mode (ECP+EPP)
This field allows you to set the operation mode of the parallel port. The setting
Normal allows normal-speed operation but in one direction only; EPP allows bidi-
rectional parallel port operation; ECP allows the parallel port to operate in bidirec-
tional DMA mode; ECP+EPP allows normal speed operation in a two-way mode.
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 1 or 3.
Onboard PCI IDE Enable (Both)
You can select to enable the primary IDE channel, secondary IDE channel, both, or
disable both channels (for systems with only SCSI drives).
IDE Ultra DMA Mode (Auto)
This field autodetects Ultra DMA capability (for improved transfer speeds and data
integrity) for compatible IDE devices. Set to Disable to suppress Ultra DMA capa-
bility.
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. The default setting of Auto will allow
autodetection to ensure optimal performance
