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.

    33Lite mode supports only one IDE controller (2 drives) and stores parameters to the top of the interrupt vectors (30:0h) so no Conventional memory needs to be reserved. Lite mode cannot be used if some software requires the top of interrupt vectors. Usually this is not a problem since only IBM ROM BASIC uses them.

    5 Tandy 1000 models with 640 kiB or less memory need to use Lite mode since the top of Conventional memory gets dynamically reserved by video hardware. This happens only with Tandy integrated video controller and not when using expansion graphics cards. It is possible to use Full mode if reserving RAM for video memory + what is required for XTIDE Universal BIOS. This would mean 129 kiB but most software should work with 65 kiB reserved.
