I newbie in Linux and I'm very interested in bootable floppy.
I read a interesting web when explain the proces for make a bootable floppy and other things.
The web is http://rz-obrian.rz.uni-karlsruhe.de/knoppix-usb/
In this web follow the same proces that explain the partner garyng.

But I arrived at the next point:
" Now we still need the usb modules (that aren't on the miniroot).
Mount the compressed KNOPPIX file (insmod cloop file=PATH/KNOPPIX && mount -t iso9660 /dev/cloop /cdrom) and copy the following files under /cdrom/lib/modules/$KERNELVERSION/kernel/drivers/usb/ to /mnt/modules/usb/:
ehci-hcd.o uhci.o usb-ohci.o usb-storage.o usb-uhci.o usbcore.o
Now you're finished modifying miniroot.
Umount it and gzip the file again."

I can't make the last point " Now you're finished modifying miniroot. Umount it and gzip the file again."

Anybody could explain me, point to point, how can I do?
