Interrupt Disable (ID) — RO. Hardwired to 0. The PCI bridge has no interrupts to
disable
Fast Back to Back Enable (FBE) — RO. Hardwired to 0, per the PCI Express* Base
Specification, Revision 1.0a.
SERR# Enable (SERR_EN) — R/W.
0 = Disable.
1 = Enable the Intel
Wait Cycle Control (WCC) — RO. Hardwired to 0, per the PCI Express* Base
Specification, Revision 1.0a.
Parity Error Response (PER) — R/W.
0 = The ICH7 ignores parity errors on the PCI bridge.
1 = The ICH7 will set the SSE bit (D30:F0, offset 06h, bit 14) when parity errors are
VGA Palette Snoop (VPS) — RO. Hardwired to 0, per the PCI Express* Base
Specification, Revision 1.0a.
Memory Write and Invalidate Enable (MWE) — RO. Hardwired to 0, per the PCI
Express* Base Specification, Revision 1.0a
Special Cycle Enable (SCE) — RO. Hardwired to 0, per the PCI Express* Base
Specification, Revision 1.0a and the PCI- to-PCI Bridge Specification.
Vendor ID — RO. This is a 16-bit value assigned to Intel. Intel VID = 8086h.
Device ID — RO.This is a 16-bit value assigned to the PCI bridge. Refer to the Intel
