Changes:

  • Changed the g_szPCFlashSuccessful string in XTIDECFG to reflect the reality - it turns out ANY key was limited to just ENTER or ESC.
  • Removed the NEC V-specific optimization I added in r602 because NEC's documentation completely fails to mention that the ROL4 instruction also changes the high nibble of AL. Huge thanks to vcfed-member dreNorteR for discovering this and also for suggesting an optimization to the physical address conversion code in IdeTransfer.asm.
  • Made some changes to the OUTPUT_AL_TO_IDE_REGISTER and OUTPUT_AL_TO_IDE_CONTROL_BLOCK_REGISTER macros as an optimization. This saves 15+12 bytes in builds without MODULE_8BIT_IDE (e.g. the PS/2 builds).
  • Other minor optimizations and cleanups.
