Syslinux - Feb 2011 - [PATCH][git-pull] doc/syslinux.txt: CONFIG and LOCALBOOT

git://git.zytor.com/users/genec/syslinux.git

Branch doc-syslinux-for-hpa

Expand upon the explanation of the usage of CONFIG (including a new
directory).  Edit LOCALBOOT to include the fact that all variants
understand LOCALBOOT type -1.  Compact the PXELINUX section to one
paragraph.

What does localboot option -1 do?
I was looking for any documents I could that display how to use
localboot all I see is "localboot 0" (which I have used and from my
understanding goes to the next boot option in the bios) in any docs I
even did "find -type f -exec grep -Hni localboot {} \;" in the
syslinux directory that i decompressed from 4.03
and I don't see anything that looks to discuss it.

Different to what?

Also, the explanation of the special -1 should stay at the end in my
opinion.

"type" 4
What makes a boot "normal"?  Do you mean disk boot?  Doesn't it
depend
on the boot device order configured in the BIOS?  In other words, how is
this different to -1?
