[syslinux] chain.c32: Chainboot failed!

[Gert Hulselmans]

When you try to boot the FreeDOS kernel with 'fs' specified, chain.c32
won't boot the FreeDOS kernel.

boot: chain.c32 fs freedos=kernel.sys
Loading the boot file...
Booting...
Chainboot failed!
boot:

It would be nicer that chain.c32 will automatically correct 'fs' to 'boot'
behavior, so it won't fail.

msdos= will probably behave the same as freedos=.
