Hi, I have problem with my 5150 64-256k (1501476 bios) motherboard, I have error code 201 and parity check 1 error.
I tryed determine whitch memory chip is wrong, but this motherboard dont like me...
I have removed all tree banks of memory chips, switched DIP SW1 and 2 to 64k RAM and i get error 1075 201
What to hell? Bank 1 is though empty. Ok, so i filled bank 1 with chips, switched SW1 and 2 to 128k, power on aaaaand....2075 201 (?!?!)
No idea what can i do.
Any help? Thanks
