 There is no hint of the file's existence in the NETROOM 3 software manual or any of the on-disk program documentation and human-readable files.This final version of NETROOM as released basically ignored DPMS.Helix licensed a version of Award Software's BIOS and developed cloaked system and video BIOSes which executed entirely in protected mode, reducing their real-mode memory footprint down to 8 KB (instead of 96 KB) and used these as run-time BIOS in conjunction with their NETROOM memory manager.
