I just noticed that I forgot a NOT is my reply to this posting that made me say the opposite I wanted to say (at least a NOT has to be added as follow):
: Your hardware is probably quite fine. Just never try to read more than the : first 64 bytes of PCI configuration space from any device, since the : remaining bytes are device specific and the PCI specifications does DO NOT : explicitely required this space to be readable without side effects. REQUIRE
Martin, I am expecting you to let us know how I am wrong. ;-)
Regards, Gerard.
