+====== Using grml for bios updating ======
+===== Common update procedures =====
+  - Download the bios files for DOS.
+  - Use actual GRML (>1.1), for older GRML versions take look below.
+  - Install grml to [[usb]] (with grml2usb).
+  - Update the FreeDOS image of GRML with the needed bios files.
+  - Boot off the usb stick with bootimage dos.
+===== Update FreeDOS image =====
+  - Boot your GRML off usb
+  - cd /live/image and search for balder10.imz
+  - unpack it with
+      # gunzip <balder10.imz >balder10.img
+  - Mount it to add the bios files you need
+      # mount -o loop balder10.img /mnt/test
+  - copy your needed bios files into /mnt/test
+  - Clean up
+      # umount /mnt/test
+      # gzip <balder10.img >balder10.imz
+  - maybe test your created image with
+      # qemu -fda balder10.img
+===== Update FreeDOS image for GRML <1.1 =====
+GRML older than 1.1 does not provide enough space on the FreeDOS image to just copy the bios files over there.
+You need to create a 2880 superfloppy based FreeDOS image.
+Use this to create a superfloppy based FreeDOS image and use the description above if you need help to install the bios files onto the new image.
+  - Boot your GRML off usb into X as you will need qemu
+  - cd /live/image and search for balder10.imz
+     # gunzip <balder10.imz >balder10.img
+  - create your new image
+     # dd if=/dev/zero of=big.img bs=1024 count=2880
+  - Equip your new image with FreeDOS
+     # qemu -fda balder10.img -fdb big.img
+       > format b:
+       > sys b:
+       > xcopy /E /N a: b:
+===== Create a standalone FreeDOS on usb =====
+If everything else does not work, your last resort is a stand alone FreeDos, either on a floppy or on usb.
+If your bios files are >1.2MB you should choose the usb ;).
+  - Boot GRML into X (qemu)
+  - Look above on how to get the uncompressed balder10.img
+  - Insert your usbstick (i'll assume it to be /dev/external)
+  - Boot FreeDOS
+     # qemu -boot a -fda balder10.img -hda /dev/external
+== Depending on your stick (bootable, allready formated) ==
+  * fdisk c:
+  * format c:
+  * sys c:
+===== Download the bios files for DOS =====
+==== Example for Intel 965 ====
+  * Download the IB bios files for DOS (also called integrators files for older bios versions)
+  * unzip the .exe file you downloaded (it's an archive)
+  * For newer biose you get a few files beside an SW.EXE
+  * unzip SW.EXE and copy it's contents to your bootable FreeDOS.
