[Àû¿ë´ë»ó: DOSBox-x]

This controls how the DOS kernel sets up the CP/M compatibility code in the PSP segment.

Several options are provided to emulate one of several undocumented behaviors related to the CP/M entry point.

If set to auto, DOSBox-X will pick the best option to allow it to work properly.

Unless set to 'off', this option will require the DOS kernel to occupy the first 256 bytes of the HMA memory area to prevent crashes when the A20 gate is switched on.

auto : Pick the best option
off : Turn off the CP/M entry point
       (program will abort if called)
msdos2 : MS-DOS 2.x behavior, offset field also
               doubles as data segment size
msdos5 : MS-DOS 5.x behavior, entry point
               becomes one of two fixed addresses
direct : Non-standard behavior, encode the CALL
           FAR directly to the entry point rather than
           indirectly.

Possible values: auto, off, msdos2, msdos5, direct.
