Hi, Mélodie,

Ok.  I'll see what I can do about getting a dmesg after the next crash
on Monday (tomorrow)

I've included the contents of /proc/cpuinfo below at the end of the
message.

I've found 3 or 4 big mistakes in what lshw has reported on other
hardware, but cannot recall the specifics since it was so long ago.  So
the report of PIII may also be a mistake.

I'm not sure how to do that.  AFAIK there is no BIOS only OpenFirmware
or EFI which have no menus.

Yes, I saw that one too.  It does not have much information.

I'll need help walking through that.
