I still think it's a spurious parity error. Note that the NMI interrupt reports the value of I/O port 61. This value has the highest bit set which indicates a parity error. But after running QAPLUS for several days I'm convinced my memory is ok. Could it be some sort of setup problem - e.g. wait states which can be configured in my AMI BIOS. BTW I do have a IDE controller/disk so Dave might be right. Regards - Tibor Sashegyi (cproto@abel.cs.curtin.edu.au)
