Bzzt, wrong... the 'b' has nothing to do with bzip2 as stated in /usr/src/linux/Documentation/kbuild/commands.txt :
"Note: the difference between 'zImage' files and 'bzImage' files is that 'bzImage' uses a different layout and a different loading algorithm, and thus has a larger capacity. Both files use gzip compression. The 'bz' in 'bzImage' stands for 'big zImage', not for 'bzip'!"
For the rest of all I know about bzlilo, bzImage, bzdisk, etc., read that file. Have a good one! :)
