up:
  1. Since grml was made as a Live CD, we need to create a bootable USB version first. Unfortunately, I only run OS X, so I had to jump through some hooks to do this. But read yourself.

  2. Preliminaries: You need Parallels (5582 works) and a USB stick with 256 MB or more.

  3. Download grml-medium. I used 0.1-rc1.

  4. Plug in the USB stick.

  5. If you wish to keep the data on the stick, now is the time to do an image with help of Disk Utility. All data will be erased soon.

  6. Setup a new Parallels instance to run Debian Linux, don't add a hard disk but boot from the ISO.

  7. Unmount the USB stick in OS X.

  8. Boot grml giving this to the loader: linux26 irqpoll

  9. Activate the USB stick in Parallels when you got into a shell.

  10. (I assume the stick is /dev/sda1, PLEASE DOUBLECHECK with dmesg.)

  11. Make a FAT16 filesystem: mkfs.vfat -F 16 -v /dev/sda1

  12. Mount the stick: mount /dev/sda1 /mnt/external1

  13. Copy the image: cp -a /live/image/* /mnt/external1

  14. Place the bootloader: mv /mnt/external1/boot/isolinux/* /mnt/external1

  15. umount /mnt/external1

  16. Install the bootloader: syslinux /dev/sda1

  17. Install the mbr: dd if=/usr/lib/syslinux/mbr.bin of=/dev/sda (NOT sda1!)

  18. Make the partition bootable: fdisk /dev/sda, a, 1, w.

  19. Shut down grml: halt

  20. Close Parallels.

  21. Grab the atl2 package at http://deb.grml.org/pool/main/a/atl2/ and put it somewhere on the stick.

  22. Unmount the USB stick in OS X again.
