Laptops :: tohd doesn't work for me

Hello. I am busy trying to learn Linux, and DSL seems a good way on my older laptop. I am having the exact same problem as was discussed at:
http://damnsmalllinux.org/cgi-bin....;t=2879
regarding not being able to use tohd=.... to copy the CDROM to my hard drive. As far as I can tell, the issue was never resolved on the forum.

I have a Toshiba 430CDT with 2.1G hard drive, one big partition containing Caldera Linux in a ext2 partition. The Caldera works fine in its partition. Booting DSL from the CD using a boot floppy works fine. I can mount the Caldera partition perfectly fine from within DSL, and it has plenty of space. So why when I invoke:
fb800x600 tohd=/dev/hda1 does it tell me that it "can't find mount point" and say there is no free space?

Thanks,
IMF

In addition, if I use the Caldera to copy the iso file to the Caldera root and issue fb800x600 bootfrom= ...., that doesn't work. If I try to copy the KNOPPIX folder containing the KNOPPIX file to the Caldera root and use fromhd=/dev/hda1, that doesn't work either.
