PCI Lock: This signal indicates an exclusive bus operation and may
require multiple transactions to complete. The ICH7 asserts PLOCK#
when it performs non-exclusive transactions on the PCI bus. PLOCK# is
ignored when PCI masters are granted the bus in desktop
configurations. Devices on the PCI bus (other than the ICH7) are not
permitted to assert the PLOCK# signal in mobile/Ultra Mobile
configurations.
System Error: SERR# can be pulsed active by any PCI device that
detects a system error condition. Upon sampling SERR# active, the
ICH7 has the ability to generate an NMI, SMI#, or interrupt.
PCI Power Management Event: PCI peripherals drive PME# to wake
the system from low-power states S1–S5. PME# assertion can also be
enabled to generate an SCI from the S0 state. In some cases the ICH7
may drive PME# active due to an internal wake event. The ICH7 will not
drive PME# high, but it will be pulled up to VccSus3_3 by an internal
pull-up resistor.
Serial ATA 0 Differential Transmit Pair: These are outbound
high-speed differential signals to Port 0.

speed differential signals from Port 2.

speed differential signals from Port 3. (Desktop Only)
Serial ATA Resistor Bias: These are analog connection points for
an external resistor to ground.
Serial ATA Resistor Bias Complement: These are analog
connection points for an external resistor to ground.
