Syslinux - May 2005 - can pxe localboot report failure to bios

<Docs>

LOCALBOOT type [ISOLINUX, PXELINUX]

     On PXELINUX, specifying "LOCALBOOT 0" instead of a
"KERNEL" option means
invoking this particular label will cause a local disk boot instead of booting a
kernel.

     The argument 0 means perform a normal boot. The argument 4 will perform a 
local boot with the Universal Network Driver Interface (UNDI) driver still 
resident in memory. Finally, the argument 5 will perform a local boot with the 
entire PXE stack, including the UNDI driver, still resident in memory. All other
values are undefined. If you don't know what the UNDI or PXE stacks are,
don't
worry -- you don't want them, just specify 0.

     On ISOLINUX, the "type" specifies the local drive number to boot
from; 0x00
is the primary floppy drive and 0x80 is the primary hard drive. The special
value
-1 causes ISOLINUX to report failure to the BIOS, which, on recent BIOSes,
should
mean that the next boot device in the boot sequence should be activated.

I think I want the bios to figure out what to boot next, as if pxe had not 
happened.  What I get from the docs is when using pxelinux, I have to specify
what
device to boot.

I'm not sure how you get that for the docs, unless you're reading the 
paragraph which explicitly starts with "On ISOLINUX..."  You want 
"localboot 0" for PXELINUX.
