( Wierd: the bit is really NAMED 'memory >overlay bit'). So it surely does NOT disable Boot-ROM. Well, I'll be damned! You're right. I got confused by the OVL (overlay) bit.

There are also $200000 kickfiles. One uses KickIt to boot them. And there's ZKick from Dan Zenchelsky. He claims it works with any memory board addressed at $200000. > I checked my A1000 and it really doesn't have any separate WCS-board. > WCS-RAM is on the motherboard. > > So I can't use any products/hacks based to replacing the WCS-board. > I need schematics to get my work on. Where did you get such a machine? Did you replace the WCS yourself? I am not aware of any A1000's sold without a WCS daughter board. > WHERE COULD I GET SCHEMATICS????? CATS.
