[syslinux] Extlinux & PXE Booting...

[Luke Hassell]

Thank you Paul for your suggestion.  While implementing it, I found my 
error.  As usual, it was an oversight of something already documented.
When using MEMDISK for < 4MB images, {gpxe,ipxe}.usb files for example, 
you have to APPEND harddisk.

Once that option was in place, I am now back to Syslinux perfection.

I have to confess, this area of SA is some of the most fun, as it is a 
foundational piece to the Internet puzzle. The work done here is truly 
amazing, well written, and documented.  Thank you all.

I would like to install it on a small active partition, sda1, so that it then PXE boots. This will allow the system to PXE boot, even if the BIOS is never configured to do so (or the CMOS battery is dead).
