The BIOS is contained in a flash ROM device – Firmware Hub (FWH) soldered directly to the motherboard and includes the code listed below. The motherboard will automatically perform a BIOS recovery operation if it detects a valid recovery disk during the boot sequence. The BIOS ROM is accessed as a single linear region in the memory space from 4GB-128kB (0FFFE0000 - 0FFFFFFFFh) and copied at the top of ISA memory (0E0000 - 0FFFFFh).
