Message:

Space optimization, added option to inline offsets for MENUEVENT structure, for situations (such as the XTIDE bios) where only one menu is needed. Ifdef'd change (set in main.asm) so either method can be used.

Location:

trunk/XTIDE_Universal_BIOS/Src

Files:

• Boot/BootMenuEvent.asm (modified) (2 diffs)
• Main.asm (modified) (3 diffs)
