Hi Philip,

Ok. I can live with it that DOS cannot handle it.
My partition scheme was not particualary smart, I agree.

In the end it didn't matter as I still get a BSOD with the margi
DVD-to-Go with a
vanilla W2K or W2K-SP4 or XP-SP2 in stream.sys.

I've to get back to IDA Pro with Hex Rays and continue to reverse
engineer it...
or there is some nasty hard to find bug in the margi driver. (I have the
source code...)

Does any one know of a Daemon Tool hack that will allow me to use a
kernel debugger?
I'm using Fathom CD for my DVD emulation currently.

Avi.
