I get the impression that what you actually meant was, "boot Knoppix from an .ISO file." While you can certainly emulate an ODD (optical disc drive) with GRUB4DOS and an .ISO file, you'd have to be certain that your OS is capable of booting from an .ISO file. That is, the OS would have to support scanning your attached disks for the .ISO file, mounting it as a loop-back device, then continuing as though it had been booted from OD. I don't believe that Knoppix supports this, but could be mistaken. See Icecube's post, below!

GRUB4DOS hooks BIOS INT 13h services to emulate an ODD.

Operating systems that do not use INT 13h (such as Windows and Linux) will not have access to such an emulated ODD; they have to use some other means to find and use the .ISO file.

AFAIK there is no known way for knoppix "inside" .iso, exception made for the isohybrided approach:

http://www.boot-land...?...=9916&st=31
Which is only "somehow inside" the .iso.

Booting with the "extracted" files Knoppix is something that has been repeatedly reported as working/not working, and then again working.
I presume the good guys at Knoppix often change the settings, we have a number of reports for DSL working (which is KNOPPIX based) but I don't seem to remember a "definite" way for KNOPPIX.

Try working your way from here :

bootfrom cheat code

This allows you to use an iso image file stored on media. Insert the CD and start with the CD. At the boot prompt, type: “knoppix bootfrom=<path to where iso is stored>. After boot up, the CD can be removed.

@Icecube



But can the cheat code be passed as a parameter (i.e. can it be added to the grub4dos entry in menu.lst)?

Can you post a complete example of KNOPPIX booting from .iso or "mixed mode" (with the kenrnel and initrd and whatever else extracted) like it was done here?:

I tested integrating dsl-4.4.10-syslinux.iso to USB stick this way:

Open DSL.ISO and extract folder “knoppix” to the root of USB.
Note: I use FAT32 as file system on USB device
Use this text in menu.lst on USB device:

title launch DSL (knoppix)
map --mem /Knoppix/boot.img (fd0)
map --hook
chainloader (fd0)+1
rootnoverify (fd0)
boot

Can you post the contents of the isolinux.cfg file of your KNOPPIX iso?

It isn't necessary to boot from CD. KNOPPIX just needs its kernel and initrd. After that it can find its ISO when you use bootfrom=.

Suppose your have named your iso "knoppix.iso" and you have put it in the root of your USB stick.
Use the following grub4dos code:

title KNOPPIX

map knoppix /knoppix.iso (hd32) || map --mem knoppix /knoppix.iso (hd32)

map --hook

root (hd32)

chainloader (hd32)

At the 'boot:' command that you see, type:

knoppix bootfrom=/dev/hda1/knoppix.iso

The /dev/??? part can be different for you:
/dev/hda, /dev/hdb, /dev/hdc, ...
or
/dev/sda, /dev/sdb, /dev/sdc, ...

or the number can be different:
/dev/hda1 ==> ISO on first primary partition
/dev/hda2 ==> ISO on second primary partition
/dev/hda3 ==> ISO on third primary partition
/dev/hda4 ==> ISO on fourth primary partition
/dev/hda5 ==> ISO on first logical partition
/dev/hda6 ==> ISO on second logical partition

Icecube,

With regard to the question that 'Wonko the sane' asked -

<But can the cheat code be passed as a parameter (i.e. can it be added to the grub4dos entry in menu.lst)?>

Do you have any answer yet? i.e. is there any way to pass this 'bootfrom=/dev/hda1' cheatcode as a parameter in G4D menu entry?

Thanks, sorry for opening an old thread.
