R
PCICMD PCI Command Register (Device 1)
Address Offset:
Default:
Access:
This 16-bit register provides basic control over the GMCH’s ability to respond to PCI cycles. The
PCICMD Register in the GMCH disables the GMCH PCI compliant master accesses to system memory.

Parity Error Enable (PERRE) RO. (Not Implemented). Hardwired to 0.
Video Palette Snooping (VPS) RO. This bit is hardwired to 0 to disable snooping.
Memory Write and Invalidate Enable (MWIE) RO. Hardwired to 0. The internal graphics device of
the GMCH does not support memory write and invalidate commands.
Special Cycle Enable (SCE) RO. This bit is hardwired to 0. The internal graphics device of the
GMCH ignores Special cycles.
Bus Master Enable (BME) RO. Hardwired to 1 to enable the internal graphics device of the GMCH
to function as a PCI compliant master.
Memory Access Enable (MAE) R/W. This bit controls the internal graphics device of the GMCH’s
response to memory space accesses.
0 = Disable (default).
1 = Enable.
I/O Access Enable (IOAE) R/W. This bit controls the internal graphics device of the GMCH’s
response to I/O space accesses.
0 = Disable (default).
1 = Enable.
