They are right, "fromhd" sets the name of the disk to search for Knoppix
files.

While "fromhd" determines the disk, "knoppix_dir" tells the directory
name of the compressed KNOPPIX*-files. The total path would then be

$fromhd -> mounts the disk to /mnt-system
$knoppix_dir -> tells the name of the KNOPPIX directory containing the filesystem in /mnt-system.

I just had a look, it seems like the cheatcode is actually listed in the Knoppix 6.4 cheatcodes (and up):

### Configuration / Persistent image ###
...
knoppix toram Copy to RAM and run from there
knoppix tohd=/dev/sda1 Copy to Harddisk and run from there
knoppix fromhd=/dev/sda1 Boot from previously copied CD-Image
knoppix bootfrom=/dev/sda1/KNX.iso Access image, boot from ISO-Image. ***)
knoppix knoppix_dir=KNOPPIX Directory to search for on the CD.
knoppix knoppix_name=KNOPPIX Cloop-File to search for on the CD.
...
