Subsystem ID (SID) — RO. The SID register, in combination with the SVID 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 SID register.
Interrupt Line (INT_LN) — R/W. This data is not used by the Intel
software the interrupt line that the interrupt pin is connected to PIRQB#.
Interrupt PIN (INT_PN) — RO.
