Line 36:
=== How will you find your kernel? ===
The bits of your kernel are somewhere on some disk (presumably the [[Bootable Disk|booting disk]], but this is not mandatory). Question is: where on the disk? Is it a regular file on a [[FAT|FAT-formatted floppy]]? is it a collection of consecutive sectors in the "reserved area" of the FAT12 floppy (in which case you may need a dedicated tool to format the disk and install the kernel on it)? Or is the floppy simply left unformatted and kernel pasted directly with a [[Disk Images|disk image tool]].
All the above options are possible. Maybe the one I'd choose myself would be to reserve enough space on a FAT12 floppy to store the ''list of sectors'' used by the kernel file. The "advantage" of being fully-FAT12 is that you don't need to re-write the bootsector every time you rewrite the kernel.
