Vendor ID — RO. This is a 16-bit value assigned to Intel.
Device ID — RO. This is a 16-bit value assigned to the Intel
controller. Refer to the Intel
for the value of the Device ID Register.
Reserved. Read 0.
Interrupt Disable (ID)— R/W.
0 = The INTx# signals may be asserted and MSIs may be generated.
1 = The AC ‘97 controller’s INTx# signal will be de-asserted and it may not generate
Fast Back to Back Enable (FBE) — RO. Not implemented. Hardwired to 0.
SERR# Enable (SERR_EN) — RO. Not implemented. Hardwired to 0.
Wait Cycle Control (WCC) — RO. Not implemented. Hardwired to 0.
Parity Error Response (PER) — RO. Not implemented. Hardwired to 0.
VGA Palette Snoop (VPS) — RO. Not implemented. Hardwired to 0.
Memory Write and Invalidate Enable (MWIE) — RO. Not implemented. Hardwired to 0.
Special Cycle Enable (SCE) — RO. Not implemented. Hardwired to 0.
Bus Master Enable (BME) — R/W. This bit controls standard PCI bus mastering
capabilities.
0 = Disable
1 = Enable
Memory Space Enable (MSE) — RO. Hardwired to 0, AC ‘97 does not respond to
memory accesses.
I/O Space Enable (IOSE) — R/W. This bit controls access to the I/O space registers.
0 = Disable access. (default = 0).
1 = Enable access to I/O space. The Native PCI Mode Base Address register should be
MSIs.
