inguaravi,

I am booting the KNOPPIX image file directly from a compact flash in an IDE adapter using the extlinux bootloader from the syslinux package by H. Peter Arvin. I tried to post the procedure for you but it was blocked for containing a banned word, although I can't imagine what that word might be. I sent a message to the site admin and hopefully the post will go through eventually. If you (or anyone else) would like it before then, contact me by PM and I can provide the details.

If your BIOS provides a startup boot menu option, you could use it to choose the disk with the extlinux bootloader. If not, you may be able to use the chainloader command in GRUB to transfer booting to the extlinux disk.
