Subsystem Vendor ID (SVID) — RO. The SVID register, in combination with the Subsystem ID (SID)
register, enables the operating system (OS) to distinguish subsystems from each other. The value
returned by reads to this register is the same as that which was written by BIOS into the IDE SVID
register.
NOTE: Software can write to this register only once per core well reset. Writes should be done as a

Interrupt Line (INT_LN) — R/W. This data is not used by the ICH6. It is to communicate to software
the interrupt line that the interrupt pin is connected to PIRQB#.
Interrupt PIN (INT_PN) — RO. This field reflects the value of D31IP.SMIP in chipset configuration
space.
