Game King 044 board DSA failure

[Tilt]

Can anyone tell me the causes for a DSA failure on a GameKing 044 processor board setup?
I'm assuming that one cause is corrupted game data.
Can another cause be using the wrong boot eprom?
Thanks,
Eric

I've seen bad GK boards cause the DSA Failure...

Take daughter board off, go to edge of a tall cliff, throw board like a frisbee as far as you can off cliff, that way you will not be pissed every time you look at it and know you paid for something that is useless, in other words it is in the daughter board not the Boot chip, it is not a flash issue it is the board, but if by a miracle you can fix them and reprogram them you will have customers.

Hi

DSA failure normally means that the SW on the flash chips has become corrupted or one of the flash chips has failed. They are programmed via a pc with specialized plug in cards (The one i worked on could program 4 cards at a time). It is also possible to program them using a special adapter board called a NIC board (Network Interface Card) and a standard PC provided that you have a boot prom that will allow you to do this. I think most failures on these are due to damage from static electricity so if you do get your hands on one of these be extra carefull to avoid zapping it.

Regards
Ian

We have tried to have ,many DSA Failure Boards reflashed and none were successful, it has to be in the board, there were some other errors like zero checksum that were re flashable, but not the DSA Failure, but we have some DSA Failure boards if you can reflash we would be interested
