You might try booting with the windows bootloader.

- Choose NO when asked to put lilo in mbr so it goes into your linux partition instead.
- copy your bootsector to a file: $dd if=/dev/hdXX of=/bootsect.lnx bs=512 count=1
(change XX to whatever your linux partition is.)
- copy the bootsect.lnx to a floppy and transfer it to C:\
- add the following line as last line to C:\boot.ini: C:\bootsect.lnx="Knoppix"

Downside is that you have to remember to do it every time you run lilo after changing it.
