Changes:

• Added a new define (USE_UNDOC_INTEL) that enables optimizations possible by using undocumented instructions available on all Intel processors and truly compatible clones. AFAIK the only exceptions are the NEC V-series and the Sony CXQ70108 processors so this option should be safe for use on the AT builds.
• Building BIOSDRVS or the BIOS without MODULE_STRINGS_COMPRESSED would fail due to the recent code exclusions so I changed them a bit. Also fixed the mistaken change to Main.asm
• Changed the Tandy specific info in Configuration_FullMode.txt so it matches the info in the Wiki.
• Optimizations and fixes in general.

File:
