Message:

Additional space optimizations, including making IdleProcessing an option in MENUEVENT. Note the fall-through from one file to another, but that there are assembler checks to ensure the proper linkage is maintained. First version of StringsCompress.pl, a perl script to make StringsCompressed.asm from Strings.asm.

Location:

trunk/XTIDE_Universal_BIOS/Src/Initialization

Files:

• DetectDrives.asm (modified) (4 diffs)
• DetectPrint.asm (modified) (2 diffs)
