Last change on this file since 265 was 242, checked in by krille_n_@…, 13 years ago

Changes:

  • Optimizations (both for size and speed) in IdeTransfer.asm and MemIdeTransfer.asm
  • Fixed a bug where the SingleByteRead/Write functions in IdeTransfer.asm would fail on 128 sector transfers.
  • Fixed some typos and errors in general, comments etc.

452; For serial drives, we pack the port number and baud rate into a single byte, and thus
453; we need to take care to properly read/write just the bits we need. In addition, since
454; we use the Port/PortCtrl bytes in a special way for serial drives, we need to properly
455; default the values stored in both these words when switching in and out of the Serial
456; device choice.

458; Writers:
459; Parameters:
460; AX: Value that the MENUITEM system was interacting with
