SM Bus Pin (SMIP) — R/W. This field indicates which pin the SMBus controller
drives as its interrupt.
0h = No interrupt
1h = INTA#
2h = INTB# (Default)
3h = INTC#
4h = INTD#
5h–Fh = Reserved
SATA Pin (SIP) — R/W. This field indicates which pin the SATA controller drives as
its interrupt.
0h = No interrupt
1h = INTA#
2h = INTB# (Default)
3h = INTC#
4h = INTD#
5h–Fh = Reserved
PATA Pin (PIP) — R/W. This field indicates which pin the PATA controller drives as
its interrupt.
0h = No interrupt
1h = INTA# (Default)
2h = INTB#
3h = INTC#
4h = INTD#
5h–Fh = Reserved
PCI Bridge Pin (PCIP) — RO. Currently, the PCI bridge does not generate an interrupt,
so this field is read-only and 0.
