I am getting a lot of NMI errors on my machine running FreeBSD 1.1.5.1.

The machine is:

386DX-25 C&T Motherboard
16Mb RAM
Adaptec 1542CF
WD 1007-A ESDI controller

The error message reads: "NMI port 61 a0, port 70 ff, port 461 ff"

The comments in the source state that this could be due to bus-master
timeouts or parity errors.

I only started getting the errors when I added the SCSI card, but it
could be just pushing the memory harder than before.

I have cured it for now by removing 8Mb of memory, but was wondering
if the error message would allow me to locate it more precisely than
that.  This RAM is all chips not SIMM, and I have several Mb that are
currently unused, but it makes it easier if you know which chips to
pull out.
