The Knoppix 3.7 CD works fine on 3 different Dell PCs.

So I created bootfloppies and put them in an old Compaq.
Now it says:
"Can't find Knoppix filesystem."
Then it drops me to a "limited shell"

I already tried "knoppix nodma" at the boot: prompt.
That did not work either.

The old Compaq has an external SCSI CDROM drive and it works.
I can boot this Compaq from the hard disk into Windows
and see the Knoppix directory structure on the CD.

But it just can't find the knoppix filesystem on this Compaq.

I took the CD back to the Dell PCs and it still works fine.
So the Compaq is the problem.

Please help.
