How many OS's are you booting?
Alot of GNU/Linux users are familiar with the term "dual booting" since that is what they end up doing for some time before they're absolutely ready to throw windows out; they dual boot their GNU/Linux distro with windows.
However, I think that sometimes people dual boot or even triple boot various GNU/Linux distros or GNU/Linux and BSD with or without windows installed on the disk.
My specific case is actually triple booting between Ubuntu 5.10 (clean install done recently), another Ubuntu 5.10 (at the moment, I will replace that with another distro) and sadly Windows XP (which I put up to test SatADSL which wasn't yet working on GNU/Linux, or at least I haven't figured it out). Windows is probably going out very soon again so it'll be a dual boot between Ubuntu and something like Zenwalk most likely.
So, anyone with quadriple-boot (have I spelled that correctly?)?
