Woo.. which cable?
Just tested the card. It is functional... however I can't get it working when:
1. the Audio cable is properly connected
2. the Hard Disk power extension cable is properly connected
Yea, I don't know why... it powers on without making a chime. I checked the manual many times and made sure that I was right. :O
The DOS Card is definitely better than Boot Camp... it can switch back and forth at the same time, and it has it's own RAM and CPU!
