Booting Knoppix4.0.2 from DOS

[ruymbeke]

I also have 5.iso for Knoppix 5 on the same partition;
Is there any way to multiboot Knop4 & 5 with no CD?

Yes of course, I have 5 iso boots on my laptop... Knoppix 4 & 5, Kanotix, accelerated knoppix, ...
Just use different path and/or filenames for the various versions of set of files (kernel, ramdisk and iso)
BTW, the iso file do not need to be called iso, you could rename it with only a letter to avoid
the upper/lower case problem then just use "bootfrom=.../5" in your menu.lst
My 2 cts,
