I could be very wrong, but isn't the motherboard on the A4000T the same as in the desktop, but with a different zorro daughterboard?
If so, why don't you just post the board off to analogic (whom I've also found to be unhelpful in the past) and not say what it came from. If not, look for a new(er) A4000 motherboard on ebay.
I have an A1200 and would dearly like its big bother - don't junk the 4000!!!
