My win98 computer is currently running as perfectly as win98 can. However, to get to this point I have to:
1. Turn it on and let it boot normally.
2. Wait for it to freeze after the splash screen.
3. Turn it off + back on.
4. Let it boot into safe mode. (where it sees nothing unusual).
5. Restart it.
6. Wait longer than I really want to.
My 486 with twice the peripherals and half the ram running linux takes about 1 fifth of this time to boot. And even if it screwed up half the time windoze did (which it doesn't), it would tell me what went wrong. (gratuitous linux plug)
