The 256-KB PAM region is divided into three parts:
ISA expansion region, a 128-KB area between 0_000C_0000h – 0_000D_FFFFh
Extended BIOS region, a 64-KB area between 0_000E_0000h – 0_000E_FFFFh
System BIOS region, a 64-KB area between 0_000F_0000h – 0_000F_FFFFh.
The ISA expansion region is divided into eight 16 KB segments. Each segment can be assigned one of
four Read/Write states: read-only, write-only, read/write, or disabled. Typically, these blocks are
mapped through MCH-M and are subtractively decoded to ISA space.
The extended System BIOS region is divided into four 16 Kbytes segments. Each segment can be
assigned independent read and write attributes so it can be mapped either to main DRAM or to hub
interface. Typically, this area is used for RAM or ROM.
The system BIOS region is a single 64-Kbytes segment. This segment can be assigned read and write
attributes. It is by default (after reset) Read/Write disabled and cycles are forwarded to hub interface.
By manipulating the read/write attributes, the MCH-M can “shadow” BIOS into main DRAM.
