I think, with my capability for pushing the wrong button at critical
moments, I might be safer to stick with ext2 then.

My motherboard is a 350MHz K6. If I have to upgrade it, I won't be too
upset, but the 350's fast enough for what I need so I there's no point fixing
it if it ain't broke. And I guess one big advantage is, I can afford to
risk breaking it ;)
Btw, I initially set up that DOS/Windoze drive I was talking about on my
spare machine - a 75MHz AMD K5. So what, it still works!
