This command will boot in the DOS environment using MSXDOS2.SYS, even if NEXTOR.SYS is available. This helps getting back some TPA memory, since MSXDOS2.SYS is smaller than NEXTOR.SYS, at the expense of not being able to use the Nextor-exclusive function calls.

This new BASIC command works the same way as the old CALL SYSTEM, but it will always load MSXDOS2.SYS even if NEXTOR.SYS is available. This helps getting back some TPA memory, since MSXDOS2.SYS is smaller than NEXTOR.SYS, but at the expense of not being able to use the Nextor-exclusive function calls (so tools like e.g. MAPDRV.COM won't work).
