I've been unable to find a way to get it done, however I'm trying these ways:
1. I have a Kodak digital camera that uses DOS format. I hex edited it to match as best I could determine to a PC Exchange bootable DOS (virtual) drive. I got as far as I/O Error
2. I have a friend who writes device drivers and file systems who may make a "simple" program to blast data from said PC Exchange bootable DOS "drive" to my compact flash.
3. I have a coworker with a PC laptop with a PC card slot, I have a CF to PC card adaptor, so that may work.
What doesn't work is Mac OS X because on my portable I don't have a PC card, I use the Jumpshot (Lexar's USB CF adaptor, nifty).
What also doesn't work is trying to get image files to write using Disk Copy.
What I wish I had was a disk image program that was liberal in what it would read and would be liberal in what it would write to. *sigh*
