Crash "not emulated EE 3d8"

Crash "not emulated EE 3d8"

[Frederic Herman]

I am trying to run an app that worked in a previous Linux box.  The 
current one is an x86_64 (AMD) fedora fc7 system.  When I try to run the 
app from dosemu, it immediately crashes, and the boot.log ends with:

Re: Crash "not emulated EE 3d8" - Update

[Frederic Herman]

I have now tested dosEmu on both a x86 and another x86_64 system with 
the same Fedora FC7 OS.  The x86 system has no problems with the 
application, and the 2nd x86_64 system crashes the same way with the 
app.  So it looks like the problem is with running on the 64 bit 
processor.

Note that I did try running some simple dos programs on the x86_64 
system and there was no crash with them.  The application that crashed 
was a dos accounting system.

This problem is fixed in the 1.4.0.1 update. It doesn't show up on
32bit by default because in that case the CPU emulator is not needed.

I rebuilt the rpm using the patch.  Now dosemu hangs when the app is 
started.  The end of the boot file shows:

Is there anyone who has build dosemu to run on fedora x86_64 platforms? 
  I really don't want to become an expert in the application.  I just 
want to use it.

PS  The app runs fine on an i386 platform.

Yes.  I use it on my Fedora 8/x86_64 machines with no problems.  I use it to
run PowerBasic/DOS and programs that I have written in PowerBasic/DOS.

Are you using a stock rpm, and if so, where I can I find it.  If you
patched it yourself, would you be willing to send me a copy?

Thanks you.
