enabled. Leave IDE HDD Block Mode on the default setting.
3.6.2 IDE Primary Master/Slave PIO/UDMA Mode,
IDE Secondary Master/Slave PIO/UDMA Mode (Auto)
Each channel (Primary and Secondary) 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 “Auto” will allow autodetection to

3.6.3 Onboard FDC Controller

can select either 3BCH/IRQ7, 378H/IRQ7, 278H/IRQ5 or Disabled. If
you install an I/O card with a parallel port, make sure there is no
conflict in the address assignments. The CPU card can support up to
three parallel ports, as long as there are no conflicts for each port.
3.6.7 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
