Alain:
I installed off a DVD, which should be the same, so my one question
before I try this is "at what point to I get it to not do an
install/update but to give me a terminal (or single-user window) so I
can execute this command. Actually, being new to this, I don't even know
if this is something I get a terminal / single-user window for as I
don't know how early I am jumping in.
Boot off the CD/DVD. At the "boot:" prompt, enter "memtest86" and
off
you go.
For what it is worth, I don't see any errors in the while process of
powering up the machine, but maybe the boot process isn't doing all the
tests you are suggesting.
Thanks,
Paul
