# For anyone who wants to experiment with reverse-engineering Compaq DeskPro 386 BIOS
# source code by disassembling one of the original DeskPro ROMs, here are the initial steps:
#
# 1) Regenerate an original ROM binary from one of the JSON-encoded ROM files
# 2) Create ready-to-assemble code by feeding NDISASM output into the TextOut preprocessor
