Reserved
Detected Parity Error: Set when the LPC bridge detects
an internal parity error. This bit gets set even if CMD.PERE
is not set.
0 = Parity Error Not detected
1 = Parity Error detected
Signaled System Error: Set when the LPC bridge signals
a system error to the internal SERR# logic.
Received Master Abort:
0 = Unsupported request status not received
1 = The bridge received a completion with unsupported
request status from the IICH
Received Target Abort:
0 = Completion abort not received
1 = Completion with completion abort received from the
IICH
Signaled Target Abort:
0 = Target abort not generated on the IICH
1 = LPC bridge generated a completion packet with target
abort status on the IICH
DEVSEL# Timing Status:
01 = Medium Timing
Data Parity Error Detected:
1 = 0 = All conditions listed below NOT met
Set when all three of the following conditions are met:
• LPC bridge receives a completion packet from the
IICH from a previous request
• Parity error has been detected (D31, F0, 06, bit 15)
• PCICMD.PERE bit (D31, F0, 04, bit 6) is set

Offset 08h: RID - Revision ID Register
Writing to this register controls what is reported in all of the RID registers in the
component. The value written does not get directly loaded in this register. However, the
value is checked to determine which value to report.
Once written, additional writes to this register must not have any affect until a core-
well reset occurs. BIOS must always write to this register in order to guarantee that the
functionality is locked.
