Ahh.. ethernet controller also not working? That triggers a memory..

It was either the ethernet chip or the USB chip, which when failed, would also interfere with the IDE bus. I forget which, and I forget what the resolution is.

But that's all here, in older threads, somewhere.

EDIT: as usual, the BBS search engine and I don't get along.. it finds 2000 non-relevant "matches" when I search for "smc_init couldn't find card" here.

Perhaps someone with better search fu than I could try the lookup?
