Some small remarks:
+ * isobybrid.c: The kernel loader which uses a FAT, ext2/3 or iso9660 file
+ * system or a PXE network.

isohybrid.c instead of isobybrid.c

isohybrid.c is only applicable for ISO's AFAIK. So maybe the following is
more appropriate (comment from perl isohybrid script):

* isohybrid.c: Post-process an ISO 9660 image generated with
*              mkisofs/genisoimage to allow "hybrid booting" as a CD-ROM
or *              as a hard disk.
