using mandrake 7.0 i couldnt seem to get lilo boot mangager with that distribution to work with my dual win2k/mandrake install...
however the lilo boot manager that comes iwth 7.2 is alot better, and i have successfully been able to use that boot manager to choose between linux and win2k.
now if you wanted to do a triple boot, youd have to look that up, sometimes the 3.5" boot disc can save alot of head ache, but i konw how neat it would be to setup a tripe or quad boot.
I know partition magic's boot magic program is good at this, you could do it on either hte lilo boot manager or the Win2k NT Loader (NTLDR) but its more work.
