Re: Crash on app startup with cpuemu=vm86(corrected)

I'm fairly certain thay when the processor is in "Long Mode"
(48-bit flat, 52-bit PAE) that Virtual86 is not supported.
"Long Mode" is only compatible with 32-bit flat, 36-bit PAE
addressing, and not 20-bit.

Subject: Crash on app startup with cpuemu=vm86(corrected)

Hi guys,
	I wonder if anyone can help me? I have a bespoke app(DPMI), which uses the 
btrieve TSR, it is misbehaving on startup. The test hardware is x86_64 Athlon 
X2 , Fedora 11(64 bit install). 

The app is working fine with _cpu_emu=vm86sim and as far back as dosemu 1.2.2.

I'd like to get this running with _cpu_emu=vm86 and dosemu 1.4.0 for extra 
speed. Here's the relevant log at crash time, it was generated by SVN 1988
