VER—Version Register (LPC I/F—D31:F0)
ID—Identification Register (LPC I/F—D31:F0)
Index Offset:
Default Value:
The APIC ID serves as a physical name of the APIC. The APIC bus arbitration ID for the APIC is
derived from its I/O APIC ID. This register is reset to 0 on power-up reset.
Index Offset:
Default Value:
Each I/O APIC contains a hardwired Version Register that identifies different implementation of
APIC and their versions. The maximum redirection entry information also is in this register, to let
software know how many interrupt are supported by this APIC.

Maximum Redirection Entries — RO. This is the entry number (0 being the lowest entry) of the
highest entry in the redirection table. It is equal to the number of interrupt input pins minus one and
is in the range 0 through 239. In the ICH6 this field is hardwired to 17h to indicate 24 interrupts.
PRQ — RO. This bit indicate that the IOxAPIC does not implement the Pin Assertion Register.
Reserved
Version — RO. This is a version number that identifies the implementation version.
