how to use grub-install with default Knoppix installation?

[Siegfried_Heintze]

I just finished the default knoppix 4.0.2 installation.

I'm told I should use grub-install because the I can specify "lang=us dma" in the configuration file. I've been reading http://orgs.man.ac.uk/documentation/grub/grub_16.html but I cannot figure out what to specify for the required device parameter.

I try grub-instal hda0 and it says "format of installed device not recognized".
I try grup-install hd0 (as exemplified in the documentation) and it says "Could not find device for /boot: Not found or not a block device."
I try "grub-install hda" and it says "Format of install_device not recognized."

I try "grub-install /dev/hda1" and it says "Could not find device for /boot: Not found or not a block device."


Thanks,
Siegfried
