Description
Upper 4 bits of base10 address of the first memory aperture
*The base 10 can be configured to various aperture sizes from 2
MB to 256 MB. (See pci_setup register). Depending on aperture
size selected, various bits will be R/W or Read Only.

RO = Read-only bits read back as zero.
Value is determined at boot time by the pci_setup register.
Indicates type 0 memory space (locatable anywhere in 32-bit
address space).
