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 what was written by BIOS into the IDE_SVID
register.
Subsystem ID (SID) — R/Write-Once. 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 what was written by BIOS into the IDE_SID register.
Reserved
Base Address — R/W. Bits [15:5] correspond to I/O address signals AD [15:5], respectively. This
gives 32 bytes of relocatable I/O space.
Reserved
Resource Type Indicator (RTE) — RO. This bit is hardwired to 1 indicating that the base address
field in this register maps to I/O space
