1 - Cleaned up documentation, with a real man page.
2 - Support for clusters larger than 16K. This would require changing
3 a lot of the SYSLINUX internals so we can read partial clusters;
4 change the current "cluster pointers" to become
5 "cluster:sector pointers".
6 - Support initrd that span multiple input media?
7 - Support a small set of DOS system calls for COMBOOT images? (Serial
8 console support makes this particularly desirable.)
9 - PXELINUX still needs work.
