I always run Knoppix as a 'Poor man's Install' on my hard drive. I use Grub4DOS to boot my multi OS system and the stanza that boots my Knoppix is something like:

title Knoppix 7.7 DVD
# MUST add the mkimage cheat code to create a persistent image file. The cheatcode can be removed once the file is created.
# Use preferences-desktop inside Knoppix to reset background wallpaper from none to supplied background.jpg.

kernel (hd0,4)/FrugalLinux/knoppix-770/linux knoppix nomce fromhd=/dev/sdb5 knoppix_dir=/FrugalLinux/knoppix-770 knoppix_name=KNOPPIX lang=uk libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 tz=localtime apm=power-off
initrd (hd0,4)/FrugalLinux/knoppix-770/minirt.gz
boot

Now, this has worked for many years but since the release of 7.6.0 I have had a problem.

Things proceed OK and then the following message flashes continuously:

Waiting (USB) Knoppix 7.7 in: /dev/sb5

After a while I get the message:

Could not mount disk to /mnt-system. Starting debugging Shell

and you are dumped at the command prompt.

I initially thought that this was a bug in 7.6 but it also happens with 7.7.

Based on the initial message displayed I wondered if a Poor Man's Installed Knoppix would now only boot from USB connected devices. I decided to replace the minirt.gz file from 7.7 with that from 7.5 and it boots! This is a good temporary solution but since the minrt.gz of 7.7 may have other useful improvements I would prefer to solve the problem properly.

I am a little surprised no one else has reported this problem - Capricorny, for example, boots this way I think?

Has anyone else had this problem?

Does anybody have a proper solution, which may involve the modification of the files within minirt.gz I guess?
