Note:

Critical error codes 00h..0Ch are the traditional codes reported through INT 24. These code assignments are mapped to error codes 13h..1Fh reported by INT21/AH=59h (see #01680). Similarly, the DOS 3.x critical error codes 0Dh..11h are mapped to INT21/AH=59h error codes 20h..24h, however, the DOS 4.0+ critical error codes are not mapped.

Bugs: Paragon Technology Systems' S/DOS 1.0 sources (a stripped down issue of PTS-DOS 6.51 with sources on CD) erroneously list DOS INT 24 error codes 12h..14h as 11h..13h, however, since the sources do not make use of these defines, this seems to be only a documentation error.
