Booting Knoppix4.0.2 from DOS

**hobz** · 01-01-2006, 04:34 PM

Hi all
I am trying to boot Knoppix 4.0.2 from Dos
I did the following
create Folder in E: called Knoppix
put knoppix .iso inside with initrd.tgz minirt.gz and a file called linux with loadlin
I go to e:/knoppix I type loadlin linux + some other options I get
invalid compressed format (err2)

Any Idea

I did it from a DOS bootable USB dongle using both lilo and grub, check in here:
http://s94002264.onlinehome.us/grub/usb_dgle4.zip
The key piece is the new minirt ramdisk boot file: minirt_usb2.gz
which is required to boot from an iso cd image file (double loop back):
http://s94002264.onlinehome.us/grub/minirt_usb2.gz
For more info and updates please have a look at this thread:

Cheers,

I will go ahead and read it but I don't think it will help
as I am having and old bios that does not support booting from USB

I am not sure you have understood how I was trying to help you.
I used DOS to boot from my USB dongle and from DOS I boot Knoppix from the ISO.
In your case, since you already have your computer booting DOS,
you only need to get the second part which is to get Knoppix to boot from the iso file using DOS.
So to get that done, you can use the second part of my setup:
You will need to use at least my minirt_usb2.gz for the iso boot
and modify your configuration files, menu.lst for grub, or the bat file you use to launch lilo.
To achieve this, please get inspired by the configuration files I used in my USB boot setup.
Good luck,
Gilles

Both this version of grub & my minirt_usb2.gz actually supports most file systems, including fat/12/16/32, ntfs, ext2/3 and reiser.
Follow what I have done on my USB setup as for the config files and where to store them.

From the knoppix-cheatcodes.txt file, you can read:
In case of a failing hardware autodetection, try booting with any of
the "no-" options as shown in the table above, like in
knoppix noagp noaudio noapm noapic acpi=off nodma nopcmcia noscsi nousb
to skip some critical parts of the autodetection system.
In your case, I would try acpi=off first, then noapic and nolapic ...
Good Luck,
Gilles
