Returns control of booting process to BIOS.
- LOCALBOOT 0 makes an attempt to boot from local device, like
0x80, etc
- LOCALBOOT -1 informs BIOS that PXE has failed and then bios will
process next entry into its boot sequence.
For example, the boot sequence (BIOS) I follow is:
1st- Boot from PXE
2nd- HDD
3rd- CD-ROM
So localboot 0 works for me ok, as "-1" does, but probably on some
servers with iSCSI booting, the sequence could be something like:
1st PXE
2nd iSCSI
3rd CD-ROM
And as that system doesn't have a local disk, this one would fail
¿anone tested this?

Pablo
