Different PSU, no success. Though, at least I did get it to boot, but the FastATA still has the issue.
I think AllegroCDFS screwed up my system, 'cause now it won't fully boot, even on the hard drive that is just IDE and connected via the normal IDE connector.
But otherwise, I received the CF card adapter and 64mb card from Danbeaver (Thanks again!) and connected it up. Seemed like it was working fine, didn't lock up when I started the fastata.driver up, when I tried copying over a smaller file, then deleting it, it worked. Then I copied over a larger file and it said 'cannot output to..' or something like that, and now it's giving me a checksum error
I'm almost 100% sure the Transcend 32GB CF card is not compatible with the voltages or something, because it overheats on this adapter as well (the other adapter completely stopped working, I think it may have gotten hot enough to fry something).
I ended up ordering another (SanDisk this time, which I've seen recommended) 32GB CF card, along with a CF card adapter just like the one Dan sent me (again, many thanks!) so I can send the one back to him. This is very frustrating, seems that just about all the hardware that I've received from this purchase has issues.
Oh, the above tests were with the stock PSU.
