PCI addresses (hex): Socket A: 43 . Socket ~: 47
This register contains an 8-bit page number that is compared with PCI address signals AD31LAD24 during memory cycles. If the page bits P7 -PO match AD31-AD24, the PCI1 050 memory-window-decode logic is enabled. This allows the memory windows to be located above the first 16M bytes of system address space, which is a limitation of the ISA bus. By using the page register, the programmer can locate the PC Card memory windows in any of the 256 separate 16M-byte pages that comprise the 4G bytes of PCI address space.
