Hi Ryan,

I have posted the bug on sourceforge. Please take a look. Thank you for helping out.

I have encoutered problems while uploading even 256KB chunks, as a result, I have only pasted the top and bottom of my log online. The complete log is about 23MB. Is there a place where I can email you the file?

If the GP fault from run_vm86() is ok, does that mean I can just change the codes that handle the fault in vm_86_GP_fault() to do nothing? Would that allow me to work around the problem?


Alvin

Doh. Well, maybe the developer of the application has an idea why it
doesn't work.

GP faults are ok as long as they are coming from the V86 process.  A GP
fault in the 32-bit dosemu code would be a problem.

You could provide a log by running dosemu -D9+a -o /tmp/log and posting
the log on dosemu.sf.net bug tracker.  You will have to split it into
256KB chunks or the file upload is not accepted.
