* How to create a boot disk:
-----------------------------
1. compile a recent kernel with many harware support,
   and many file systems (as ext2, fat, reiser, ntfs)
   with make bzImage (do not use DMA by default)
2. use rdev on the image:
   rdev bzImage /dev/fd0
   rdev -r bzImage 49152 (49152 = ask disk, and read from 0)
   rdev -R bzImage 0 (to make the root RW and allow to login)
3. dd if=bzImage of=/dev/fd0


* How to create a root disk:
-----------------------------
1. dd if=/dev/zero of=image count=3733 bs=1k
2. mkfs.minix image
3. mount -o loop -t minix image /mnt/image
4. remove debug data from binaries executables
   libraries and programs to save space:
   program:...............objcopy --strip-all program
   shared library:........objcopy --stripdebug library.so
5. copy all files to /mnt/image
6. umount /mnt/image
7. cat image | gzip -9 > image.gz
8. dd if=image.gz of=/dev/fd0
