Unhandled exception in old DOS application

Mon May 13 21:32:51 CDT 2002

Hi,

I hope this is the correct place to ask...

Up until the 20020411 wine release my old DOS application worked well...for the
last ~2 years. (Thanks all of you!)
With both 20020411 and 20020509 releases the wine issues an Unhandled exception
report and starts the debugger.

bash-2.05$ wine cardload.exe -- -a340 -f"c:\\\winapps\\\winphone\\\cardload.hex"
Could not stat /mnt/fd0 (No such file or directory), ignoring drive A:
Warning: unprotecting the first 64KB of memory to allow real-mode calls.
         NULL pointer accesses will no longer be caught.
wine: Unhandled exception, starting debugger...
err:int:DOSVM_Loop MsgWaitForMultipleObjects returned unexpected value.

This application just downloads firmware (cardload.hex) to an old ISA card.

What can be done to fix this, where should I begin looking to fix it, who
knows if there is a fix already, any ideas how to fix it?

I can send the cardload.exe file if anyone is interested, its 48K.
