FAI installation on new PCs with UEFI BIOS

[Wolfgang Walkowiak]

Hi Thomas (et al.),

thanks.  I just discovered a work-around for my issue with the UEFI 
BIOS looking at
   http://www.syslinux.org/wiki/index.php/SYSLINUX#LOCALBOOT_type

Basically it suggests to replace the stanca
   LOCALBOOT 0
by
   LOCALBOOT -1
in the appropriate PXELINUX menu.  This causes the BIOS (and also the UEFI 
BIOS of the ASUS motherboard we have) to accept the failure of the PXE 
boot and move on to the next entry in the boot order.  I tested it also 
with one of our older PCs without UEFI BIOS for which it worked as well.

This trick saves me from spending some time on debugging a combination of 
pxelinux and syslinux boot menus.  (Sorry, no recipe for that.)

Cheers,

w.w.

P.S.: Here are the contents of my localboot.inc snippet:

# localboot.inc
label local
MENU LABEL BOOT FROM ^LOCAL HARDDISK
# request booting from local disk -- has issue with UEFI-BIOS
## LOCALBOOT 0
# set LOCALBOOT to -1 to signal failure instead
LOCALBOOT -1
