I had a machine with multiple OSes chosen at startup with OS/2 Boot Manager, including OS/2 Warp, Windows NT Workstation 4, and Redhat 5.0 which came on a CDROM labeled Pink Tie 5.0. (It was late '90s I guess. I used MSDOS before that. And a Commodore 64 before that) I believe I put a mail server on it (the Redhat partition) while I was still on dial-up (128K ISDN). The mails waited somewhere until I got online and signalled to send them to me. But then upgraded it to DSL. I was still running Redhat 7.3 with my mail server until 2006, even though Redhat 9 and Fedora were out by then. In 2006, I shut it down and bought a Windows 98 laptop to travel around Central America for a year. The Guatemalans laughed at my Windows 98 laptop--they were running Vista. When I got back to the US in 2007, and broke the laptop screen, oops, I bought a $300 desktop PC that had Lindows installed.
