    Knoppix 3.4 boot disk

    Does anyone know how to create a boot disk for KNOPPIX_V3.4-2004-05-04. In the new cheatcode it still says you can " you can create a bootable floppy disk by issuing (on Linux) dd if=/cdrom/KNOPPIX/boot.img of=/dev/fd0 bs=18k" but there is no /cdrom/KNOPPIX/boot.img file.

    Thanks in advance,

    Yes, this is true. There is no "/cdrom/KNOPPIX/boot.img" in KNOPPIX 3.4

    So I used "/cdrom/KNOPPIX/boot.img" from KNOPPIX 3.3 to create a boot floppy.

    I put the boot floppy in the floppy drive and KNOPPIX 3.4 CD in the CDROM drive.

    Now the boot floppy boots and tells the system to boot from the CDROM and I can now boot KNOPPIX 3.4

    Curiously, booting from a v3.3 boot floppy does mostly work. It still looks for kernel modules for kernel 2.4.2-xfs, which aren't there.

    Reason there isn't a boot disk for v3.4 is probably that the files necessary to boot the new 2.4 kernel alone are ~1.8M (look in the /boot/isolinux dir on the CD) -- too big to fit on a floppy, even a floppy formatted in MS DMF. Has anyone got (or ever seen) a drive that reads 2.88M disks?

    I am actually trying to figure this out so that I can boot from a thumb drive (32M). I can boot version 3.3 this way, but I am not sure what needs to be on the disk for 3.4

    It's a little confusing because of the option to boot between the 2.4 and 2.6 kernels. I would be happy booting to a 2.4 kernel. Any thoughts?

    Wasn't there talk of now being able to create a two-disk boot set?

    More info re: this...

    On this link

    http://www.knoppix.net/forum/viewtop...210&highlight=

    it appears that Klaus makes a recommendation regarding remastering a CD and the lack of boot.img in 3.4

    Would any of this apply to making a boot disk? At least in my case, I don't care if it fits on a floppy necessarily, as long as it fits on my 32M thumb drive.

    Any help greatly appreciated.

    Hello:

    I've finally been able to download Knoppix 3.4, but I have noticed (as others have) that there's no disk image to create a boot disk from.

    I would like to attemp a Knoppix HD install to an ancient Acernote Light 350P laptop which has no CD-ROM with what I have seen is called a 'Poor Man's Installation' ie: copying the CD's KNOPPIX directory to a FAT32 partition on the hard disk and booting from A:\ ...

    But it seems that a floppy/set of floppies is absolutely necessary.

    Any ideas as to how to go about generating these?

    Thanks in advance,

    CIV

    pau1knopp: Why don't you experiment, and let us know your results?

    I would think that, if you could make a USB thumb drive bootable for Knoppix v3.3, that you could replace MINIROOT.GZ, VMLINUZ, and SYSLINUX.CFG with their Knoppix 3.4 counterparts (you'd probably have to rename 3.4's ISOLINUX.CFG to SYSLINUX.CFG).

    I tried to format a 1.72M floppy (using WinImage), and use all the files from the Knoppix v3.3 boot disk, except replacing MINIROOT.GZ with v3.4's MINIRT24.GZ (renaming it to MINIROOT.GZ). It was still too big to fit.

    More ideas on creating a bootable USB drive can be found on Puppy Linux's "flash-Puppy" page (and a pre-compiled syslinux binary for DOS can be found on Puppy Linux's download page).

    Well hi ,

    there is a way to make a bootdisk but loosing all SCSI and USB-modules iirc (so it definietly fits):

    http://debian.tu-bs.de/knoppix/CeBit/make_floppy_3.4.sh

    should help you to do it. You can also customize that script e.g. to include the USB-modules, but to drop the SCSI ones or vice-versa ...

    We were thinking about a two-floppy boot, but no one has done that yet.

    cu

    Fabian

    PS: As always: If this information is helpful to you, please add it to the docs.

    The boot floppy itself seems to work fine, except...it won't boot into the CD or into an ISO on the hard drive.

    I've tried multiple times, in multiple ways, including using the "knoppix_dir=", "knoppix_name=", and "bootfrom=" cheatcodes. No joy.

    Is there something more esoteric to nuke out of minirt24 besides the SCSI modules?
