Why doesn my XFS kernel fit on a bootfloppy that I make with mkbootdisk?
XFS is a huge amount of kernel code which means that your kernel is probably to big to fit on a boot floppy together with a inital ramdisk and scsi drivers. There is patch available for mkbootdisk to properly format a floppy with a larger size. Your mileage may very on booting overformatted floppy’s of 1.68 or 1.72MB. The patch can be found at http://iserv.nl/files/xfs/mkbootdisk.large.patch Use the /dev/fd0u1680 for making a 1.68MB floppy. Another method is building XFS as module but this is probably more hassle then trying to boot a superformatted floppy.
