Bloat has grown the kernel too large to fit on a floppy. Most people who can not set their BIOS to boot from CD are using a program like SBM or XOSL to boot the CD. What is this hardware problem that you speak of? If we know what the problem is we may be able to tell you how to work around it.

Can't be a driver problem, the OS (and thus the drivers) are not loaded at that point in the boot process. Only software it could be is the BIOS. Sure sounds like a strange problem. The CD otherwise works fine?

That sounds like SBM, I gave you the link above.

I'll try the Smart Boot Manager to boot Knoppix. I appreciate your help.
I guess that there could be a problem where a CD drive destroys writeable media if it somehow writes when it should read. Never heard of a real case of it though. You seem to have done some of the steps that would prove that something is happening to CD with your above tests, but hardly enough. I would burn CD's on a different system (or get some burnt CDs) and see if I could read them on the "different computer" above, then and only then try them in the suspect computer. Then, if the suspect computer fails, see if they can still be read in the "different computer" or if they are now bad. And if bad a tool like ISOBUSTER might give you some insight on what is now wrong with the CD. Of course, I would look at the CD closely to be sure it wasn't becoming extremely scratched, but I would expect you have already done that.
There is also a chance that you are writing the CD too fast; I always recommend 4x or as slow as the drive will go (a few new drives seem to burn no slower than 8x). Higher burn speeds do cause problems. See http://www.knoppix.net/forum/viewtopic.php?t=17788
and
http://www.knoppix.net/forum/viewtop...?p=78925#78925
for examples, search the forums for the words burn and speed for many more. And, of course, try SBM. You might not even need it once you resolve the other issues, but it will not hurn and will avoid any BIOS CD boot problems.
Problem booting Freeduc 1.5
I have recently purchased a new computer & have a copy of Freeduc 1.5 burn't to a re-writeable disc, It seems to boot fine on my other computers but when I select to boot from my disc drive the screen goes blank & about a minute later it proceeds to load Windows XP. my disc drives are ASUS DVD-E616P3H & a LITE-ON DVDRW SOHW-1633S are these drive known for problems when booting Freeduc?
Can anyone help me?

So you never see the Knoppix boot splash screen, correct? If that's the case, I'd suspect that the CD-ROM can't read the CD properly. Try burning a new copy at a slower speed.
