The situation certainly has improved. _New_ machines generally work
perfectly. On the other hand, I have a Celeron machine from 1998 here
that hangs at bootup if the BIOS spots a >32GB drive. Still quite old,
I know, but I view getting the most out of old hardware as one of the
advantages of free OSes. I don't see the BIOS problem ever fully going
away until the BIOS is as replaceable as the OS. Still, it shouldn't be
the job of the OS to fix that.

It just happens that this 486 has exactly 32MB of RAM, so.... ;-)

I know what you mean. People will quite happily throw away stuff just
because they got something better. I don't because I enjoy making good
stuff out of would-be junk :-)

Trying stuff out is what I'm here for. I'd noticed I'd started talking
about Linux like it was the only OS in the universe, so I thought I'd
broaden my mind a little.
