11. PCI Slot 1 Mode Selection (JP37, 38)
By default, the onboard IDE uses Programmable I/O (PIO) Mode and PCI Slot
1 uses BUS Master Mode so that BUS Master expansion cards on PCI Slot 1
can be used. If you want the onboard IDE to use BUS Master mode and are not
planning to use a BUS Master card on PCI 1, then you may select Slave
mode for PCI 1.
