On x86_64 running Stretch, I also get this when trying to run unzip32 from DJGPP which is at the following URL:
http://www.delorie.com/pub/djgpp/current/unzip32.exe Changing the CPU type to "full" allows the command to run however it quickly crashes with: ERROR: Fault in dosemu code, in_dpmi=1 ERROR: cpu exception in dosemu code outside of DPMI client! trapno: 0x0e errorcode: 0x00000004 cr2: 0xa028601d eip: 0x564da024d887 esp: 0x7ffe84229960 eflags: 0x00010246 cs: 0x0033 ds: 0x0000 es: 0x0000 ss: 0x002b ERROR: Please report the contents of ~/.dosemu/boot.log at http://sourceforge.net/tracker/?atid=457447&group_id=49784&func=browse It would be even more helpful if would recompile DOSEMU and reproduce this bug with "debug on" in compiletime-settings. Page fault: read instruction to linear address: 0xa028601d CPU was in user mode Exception was caused by non-available page I have additionally attached the boot.log file.
