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.

 TransferBlockToOrFromXTCF:
-    ; 8-bit DMA transfers must be done withing 64k physical page.
+    ; 8-bit DMA transfers must be done within 64k physical page.
     ; XT-CF support maximum of 64 sector (32768 bytes) blocks in DMA mode
     ; so we never need to separate transfer to more than 2 separate DMA operations.
