Hi Markus.....Wow you are pretty knowledgable with this stuff!!! I don't have a THOROUGH knowledge of this unfortunatly! I am trying to logically figure it out.
Well I would rather stay away from using NTLDR. I have always used LILO and I am more comfortable with messing with that than NTLDR.
OK so when I am prompted as to where I want LILO to go, I will choose MBR.

Here's my plan:

HDA1 for WINxp
HDA2 for KNOPPIX
HDA3 for SWAP

SO....I will then edit LILO.CONF to show this line: boot=/dev/hda

OK I think I see....I have to specify that in LILO.CONF. This part I am not clear on. When I install KNOPPIX and ask LILO to be written to MBR instead of LINUX partition, isn't that all I need to do, except for editing LILO.CONF afterwards to be able to boot winxp? I see where I have to put in boot=/dev/hda in LILO.CONF.....I understand that part.

As far as using CFDISK to set HDA1 to FAT32....that may be the only choice, then CONVERT my WINxp installation later on to NTFS....I remember doing that a while ago...no big deal.

So basically I just have to make sure in LILO.CONF that this line is in there: boot=/dev/hda
Let me know if I am making this more difficult than it really is!!! Sorry fo repeating myself so much......So to sum it up.....By choosing to install LILO to MBR, I do that and also put the boot=/dev/hda line in LILO.CONF.....You are not confusing, I just have a problem with needing very explicit instructions! OK so I will use KNOPPIX to partition my disk, and for my Winxp partition, using CFDISK I will choose as "type" "FAT32" then let Winxp format that partition when I am installing. Whew! bob
