Introduction
Complementary Components include:
P64H2 PCI-X Hub
(P64H2)
The P64H2 PCI-X Hub provides a 16-bit connection to the MCH for high-
performance I/O capability and two 64-bit PCI-X interfaces.

Special Features
Recovery from AC Power Loss
BIOS provides a setting for you to determine how the system will respond
when AC power is lost and then restored to the system. You can choose
for the system to remain powered off (in which case you must hit the
power switch to turn it back on) or for it to automatically return to a power-
on state. See the Power Lost Control setting in the Advanced BIOS Setup
section (Peripheral Device Configuration) to change this setting. The de-
fault setting is Last State.

PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
i2DML-8G2/i2DML-iG2. All have an onboard System Hardware Monitor chip
that supports PC health monitoring.
Fan Status Monitor with Firmware/Software On/Off Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin chassis fans are controlled by the power management func-
tions.
I/O Controller Hub (ICH4)
The ICH4 is the fourth-generation I/O Controller Hub subsystem that inte-
grates many of the input/output functions of the chipset, including a two-
channel ATA100 Bus Master IDE controller. The ICH4 also interfaces with
PCI and various communications ports. Nearly all communications between
the GMCH and the ICH4 takes place over the hub Interface, which is a 66
MHz/266 MB/s bus.
