Heya Christian,

I use the same kernel to boot from a hard-disk, and also from a CD-ROM, and both work correctly.

The following patch (against latest CVS) enables the floppy to boot correctly.  This patch was suggested by Jani Monoses
(http://lists.nongnu.org/archive/html/qemu-devel/2004-08/msg00132.html).

Given that it works with this patch, I can't see how it could be a kernel config issue, no offence intended :)
