what is bzimage?
I went to build a custom kernel with make-kpkg, and noticed the option to build a `zimage' kernel, instead of `bzimage' kernel (the default). But I can't find any documentation anywhere of what the difference is between these two. I've looked in the Kernel-HOWTO, and in all the documentation in /usr/src/linux. So, can someone explain what `bzimage' is, and why I might or might not want it? Thanks. =-=-=-=-=-=-=-=-=-=-=-= David S.

Some old boot loaders can't handle it (though the latest version of lilo and loadlin can). There is also a problem booting them on some laptops. For the most part, it doesn't matter though. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] . Trouble? e-mail to [EMAIL PROTECTED] .

If my limited understanding is correct, zimage is just a compressed copy of the kernel image. Is bzimage the same, but using a different (better) compression algorithm?

As the number of features has increased, kernels have gotten somewhat larger. There was a limit on the size of the compressed kernel with zImage (I don't know what the limit was), and bzImage has a larger limit, like 1 MB compressed (~2 MB uncompressed). This started in 1.3.73. And is this documented somewhere? Bits and pieces in /usr/src/linux/Documentation/Changes and the LILO and LOADLIN documentation. I believe it was more fully documented in the later pre-2.0 kernel packages.

There is a limit to the size of a zImage kernel (1 meg) which requires changes to the bootload/compression that result in a bzimage (which can be larger than 1 meg). There are several ways you can construct a custom kernel that is below the 1 meg and fit in a zImage. In the mean time, have you tried the tecra kernel? It is in the disks-i386 directory under the tecra/ subdirectory. You will find a drivers and rescue disk image there. Give it a try.
