SVID—Subsystem Vendor ID
Address Offset: 2Ch
Default Value:
This register should be implemented for any function that could be instantiated more
than once in a given system,. The SVID register, in combination with the Subsystem ID
register, enables the operating environment to distinguish one subsystem from the
other(s).
Software (BIOS) will write the value to this register. After that, the value can be read,
but writes to the register will have no effect. The write to this register should be
combined with the write to the SID to create one 32-bit write. This register is not
affected by D3
SID—Subsystem ID
Address Offset: 2Eh
Default Value:
This register should be implemented for any function that could be instantiated more
than once in a given system,. The SID register, in combination with the Subsystem
Vendor ID register, make it possible for the operating environment to distinguish one
subsystem from the other(s).
Software (BIOS) will write the value to this register. Then, the value can be read, but
writes to the register will have no effect. The write to this register should be combined
with the write to the SVID to create one 32-bit write. This register is not affected by

SVID (SVID) — R/WO. These R/WO bits have no ICH8 functionality.
SID (SID) — R/WO. These R/WO bits have no ICH8 functionality.
Capability Pointer (CP) — RO. This field indicates that the first capability pointer
offset is offset 50h (Power Management Capability).
Interrupt Line — R/W. The ICH8 hardware does not use this field directly. It is used
to communicate to software the interrupt line that the interrupt pin is connected to.
