|Well, your PCMCIA (pc-card) reader should support bootable media, so I suspect the problem is that the media isn't bootable. Given that most uses for CF cards involve simple data storage, some (but not all) vendors don't provide completely ATA compliant parts. I'm sure there is some reason for this, but I'd ask around, and see what other folks are using.|
If I knew which host OS you were using, I might could give you a bit of advice on further tests. I can say this - if you want to eliminate the possibility of your adapter causing problems, try a CF-IDE adapter board. They can be had reasonably cheap - and make your CF card look like a true ATA device.
