What LAN card is it?
And more importantly, is it listed as a known working card by whatever driver you're using (cnet/3com/prism ?)

I think I've seen a card that behaved like this in an early revision A1200, but not in a later revision. You might have to get a different card.


You may well be onto something there Neil. AFAIK, there are at least 2 versions of the AA Gayle, but I dunno what they changed/fixed with it.

as you can see pin 5 of gayle goes directly to the R715Y so why do some people suggest putting a cap between them ?
Is it to allow for an incorrect track on the mobo or is it to delay the reset signal from Gayle for a few milliseconds.  
would i be better of just using a jumper wire straight to pin 58 of the pcmcia slot ?  :-D


Nope. the tracks on the motherboard are fine, the problem is Gayle doesn't generate the reset signal on startup. BTW, that pic is slightly wrong, the CC_Reset is active high, not active low as the '_' prefix suggests, that resistor is just a pulldown to make sure there are no false resets generated.

The fact your HD doesn't spin up is worrying, I thought IDE drives always spun when powered up until they were told to sleep, could it be a weak PSU?
 You could try removing the HD and any CPU card , plug the network card in and see if it gets to the purple insert disk screen.

BTW, those 'big black resistors' are just axial ferrites to filter out any noise on the power lines, if they went wrong you'd have bigger problems than this.
