2.6.3 PCI to ISA Bridge
An ITE IT8888G PCI to ISA bridge single function device connects the on-board
IEM-LX-800 ISA bus ETX-X2 connector to the GeodeLink™ PCI bridge. The IT8888G has
a PCI specification v2.1 compliant 32-bit PCI bus interface and supports both PCI Bus
master and slave. The PCI interface supports both programmable positive and full
subtractive decoding schemes. Some of the features of the IT8888G PCI to ISA bridge are
listed below.
