Using EBX:
Note that using EBX under the Microsoft Windows 3.0 DOS box in standard mode
or after Microsoft Windows 3.0' termination after running standard mode, for
32-bit addressing in real or virtual 86 mode, is likely to crash the system
due to the fact that apparently the Windows 3.0 DOS box trashes EBX while
servicing interrupts, turning bit 18 of EBX to 1 and thus causing unwanted
segment violation errors. Use of EBX in calculations is likely to cause
spurious errors and may yield unpredictable behaviour of your code under
the aforementioned circumstances.
