2.4.4.2 PCI-to-ISA Bridge
The ISA edge connector on the IOWA-GX facilitates ISA bus expansion. The ISA edge
connector is interfaced to the CPU, through an ITE IT8888F PCI to ISA bridge single
function device. The ITE IT8888F is a bridge between the PCI bus and the ISA bus. The
32-bit PCI bus interface on the IT8888F is compliant with PCI Specification v2.1 and
supports both PCI Bus Master & Slave.
