tr, Thanks for your help
I never meant to imply that 'bootfrom' doesn't work
-- Only that I was unable to get it to --.

After I issued 'knoppix tohd=dev/hda6' I noted that
(on return to Win98se) my G: drive (which Linux
calls hda6) had a new subdirectory (subfolder)
named KNOPPIX which contained a large file also
named KNOPPIX (no .iso or any extension at all).

I am not now at home now but seem to remember
having tried
1. knoppix bootfrom=/dev/hda6/KNOPPIX.iso
2. knoppix bootfrom=/dev/hda6/KNOPPIX
3. knoppix bootfrom=/dev/hda6/KNOPPIX/KNOPPIX
4. knoppix bootfrom=/dev/hda6/KNOPPIX/KNOPPIX.iso
-- and possibly others as well --

all resulted in the ". . . not mountable." message.

What is truly puzzling about this is that when I
issue 'knoppix fromhd=/dev/hda6' it works flawlessly!

Thus it seems that the 'iso file' is OK and I earlier
addressed the 'kernel version' issue. Thanks again
for your help -- any other ideas ?? -- JW --
