Base Address — R/W. Bits [31:10] correspond to memory address signals [31:10], respectively.
This provides 1 kB of locatable memory space aligned to 1-kB boundaries.
Reserved
Prefetchable — RO. Hardwired to 0; indicates that this range should not be prefetched.
Type — RO. Hardwired to 00b; indicates that this range can be mapped anywhere within 32-bit
address space.
Resource Type Indicator (RTE) — RO. Hardwired to 0; indicates that the base address field in this
register maps to memory space.
Subsystem Vendor ID (SVID) — R/W-Special. This register, in combination with the USB EHCI
Subsystem ID register, enables the operating system to distinguish each subsystem from the others.
NOTE: Writes to this register are enabled when the WRT_RDONLY bit (offset 80h, bit 0) is set to 1.
Subsystem ID (SID) — R/W-Special. BIOS sets the value in this register to identify the Subsystem
ID. This register, in combination with the Subsystem Vendor ID register, enables the operating
system to distinguish each subsystem from other(s).
NOTE: Writes to this register are enabled when the WRT_RDONLY bit (offset 80h, bit 0) is set to 1.
