well working on a deviced driver to use linux partitions is not easy, I wanted to make ext2 partitions look like a cdrom so I can use mscdex to give it a drive letter.  I would appreciate any low level info on ext2 partitions or if something like this extists, for me to be told so I don't waste my time coding it ;P
 hows this sound?
devicehigh=c:\pharos\ext2.sys -d:mscd0002 -p=/dev/hda8
