Interrupt Disable — R/W.
0 = Enable.
1 = Disables LAN controller to assert its INTA signal.
Fast Back to Back Enable (FBE) — RO. Hardwired to 0. The integrated LAN controller
will not run fast back-to-back PCI cycles.
SERR# Enable (SERR_EN) — R/W.
0 = Disable.
1 = Enable. Allow SERR# to be asserted.
Wait Cycle Control (WCC) — RO. Hardwired to 0. Not implemented.
Parity Error Response (PER) — R/W.
0 = The LAN controller will ignore PCI parity errors.
1 = The integrated LAN controller will take normal action when a PCI parity error is
VGA Palette Snoop (VPS) — RO. Hardwired to 0. Not Implemented.
Memory Write and Invalidate Enable (MWIE) — R/W.
0 = Disable. The LAN controller will not use the Memory Write and Invalidate command.
1 = Enable.
Special Cycle Enable (SCE) — RO. Hardwired to 0. The LAN controller ignores special
cycles.
Bus Master Enable (BME) — R/W.
0 = Disable.
1 = Enable. The Intel
Memory Space Enable (MSE) — R/W.
0 = Disable.
1 = Enable. The ICH7’s integrated LAN controller will respond to the memory space
I/O Space Enable (IOSE) — R/W.
0 = Disable.
1 = Enable. The ICH7’s integrated LAN controller will respond to the I/O space
detected and will enable generation of parity on DMI.
