OK - I've now run the 4.0.2. DVD. Lack of disk space on my Windows 98 machine meant I had to use my NTFS configured laptop. Nevertheless, this was configured intially to run the 4.0.2. CD cloop file from the hard disk.
I simply replaced the single KNOPPIX cloop file with the two files KNOPPIX, KNOPPIX2 from the 4.0.2 DVD and it booted up into the DVD version no problem.
I am beginning to wonder if PaulBx1 tried to run the 5.0.0 DVD using the linux and minirt.gz files from the 4.0.2 CD. If so then I would suggest updating these files on his hard drive and see how it goes.
