[syslinux] does PXE have a BIOS device addr?

[Eric A. Hall]

I noticed in isolinux that I could use -1 to specify the last boot device,
which is my PXE here (I've got it setup to get called after nothing else
works). I'm wondering, is there a standard address reference for PXE?
Like, floppies are usually addressed as 0x00 and first HD is usually
addressed as 0x80, is there a standard for PXE?

It'd be great to have a reliable "boot from PXE" option and that seems
like the way to go...

Thanks
