Bit	Description

Index 40h	PCI Function Control Register 1 (R/W)	Reset Value: 39h

7:6	Reserved. Must be set to 0.

5Reserved. Must be set to 0.

4PCI Subtractive Decode.

0:Disable transfer of subtractive decode address to external PCI bus. External PCI bus is not usable.

1:Enable transfer of subtractive decode address to external PCI bus. Recommended setting.

3Reserved. Must be set to 1.

2Reserved. Must be set to 0.

1PERR# Signals SERR#. Assert SERR# when PERR# is asserted or detected as active by the Core Logic module (allows PERR# assertion to be cascaded to NMI (SMI) generation in the system).

0:Disable.

1:Enable.

0PCI Interrupt Acknowledge Cycle Response. The Core Logic module responds to PCI interrupt acknowledge cycles.

0:Disable.

1:Enable.

Index 41h	PCI Function Control Register 2 (R/W)	Reset Value: 00h

7:6	Reserved. Must be set to 0.

5X-Bus Configuration Trap. If this bit is set to 1 and an access occurs to one of the configuration registers in PCI Function 5 (F5) register space, an SMI is generated. Writes are trapped; access to the register is denied. Reads are snooped; access to the register is allowed.

0:Disable.

1:Enable.

Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[9].

Second level SMI status is reported at F1BAR0+I/O Offset 04h/06h[5].

4Video Configuration Trap. If this bit is set to 1 and an access occurs to one of the configuration registers in PCI Function 4 (F4) register space, an SMI is generated.Writes are trapped; access to the register is denied. Reads are snooped; access to the register is allowed.

0:Disable.

1:Enable.

Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[9].

Second level SMI status is reported at F1BAR0+I/O Offset 04h/06h[5].

3Audio Configuration Trap. If this bit is set to 1 and an access occurs to one of the configuration registers in PCI Function 3 (F3) register space, an SMI is generated. Writes are trapped; access to the register is denied. Reads are snooped; access to the register is allowed.

0:Disable.

1:Enable.

Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[9].

Second level SMI status is reported at F1BAR0+I/O Offset 04h/06h[5].

2IDE Configuration Trap. If this bit is set to 1 and an access occurs to one of the configuration registers in PCI Function 2 (F2) register space, an SMI is generated. Writes are trapped; access to the register is denied. Reads are snooped; access to the register is allowed.

0:Disable.

1:Enable.

Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[9].

Second level SMI status is reported at F1BAR0+I/O Offset 04h/06h[5].

1Power Management Configuration Trap. If this bit is set to 1 and an access occurs to one of the configuration registers in PCI Function 1 (F1) register space, an SMI is generated. Writes are trapped; access to the register is denied. Reads are snooped; access to the register is allowed.

0:Disable.

1:Enable.

Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[9].

Second level SMI status is reported at F1BAR0+I/O Offset 04h/06h[5].
