#0 lore raw

I recently had to reinstall linux on a file server. Unfortunately I forgot that I needed a 32-bit kernel and installed a 64-bit kernel instead. When trying to run DOSemu I got the message that "vm86 plus service not available for your kernel". I noticed in the documentation that SIMX86.exe can substitute for vm86. Does anyone know where I can get a copy of SIM86.exe? Or any other help with this problem?

Any help would be greatly appreciated.

Thanks in advance.

Make sure that the DOSEmu configuration file doesn't have $_cpu_emu
option uncommented (without #) and thats it.
You don't need SIMX86.EXE.

# Usage of cpu emulation: "off" (requires /proc/sys/vm/mmap_min_addr= 0), # "vm86" only (default) or "full" (vm86 and DPMI, experimental!). # Use "vm86sim" or "fullsim" to use simulation instead of JIT code generation.

# $_cpu_emu = "vm86"

If you still have problems, please send your .dosemu/boot.log file. Thanks.

Make sure that the DOSEmu configuration file doesn't have
$_cpu_emu option uncommented (without #) and thats it.
You don't need SIMX86.EXE.

The $_cpu_emu configuration variable does not exist in my dosemu.conf file.
It is not mentioned in any documentation of my version of DOSemu (version 1.2.2.0)
I have not been able to find any reference to it in the on-line documentation for version 1.2 or version 1.4.

It is on my dosemu.conf.

Are these comments your own or are the taken from your dosemu.conf file?

Thats an extract from my dosemu.conf file.

DOSEMU-1.2.2.0 is coming up on Linux version 2.6.13-15-default ----End of boot.log file-----

In my boot.log I have the following 2 lines:
WARN: vm86plus service not available in your kernel
WARN: using CPU emulation for vm86()

Maybe thats a feature of DOSEMU 1.4 only and is not available in
1.2.2.0.
Try DOSEmu 1.4, it should fix the problem and run fine under a
64bit kernel without the need for SIMX86.EXE.

Thank you for your help.

You are welcome!
Good luck!
