Subject: Re: Dos App hangs with DPMI / PIC problem
Date: Fri, 17 Sep 2004 04:18:34 +0000 [thread overview]
Message-ID: <BAY15-F36tNTlwKg7Bj000c8d05@hotmail.com> (raw)
Hello,
1. Tried
>e c316:903a EB
>e c316:903b 08
the trace becomes different, but the app still hangs...
2. Also tried using freedos instead of msdos. Same thing...
BTW, the app is actually a client - server app running on netx. Not sure if
this is relevant...
Thank you, everyone, for helping out!
