Just answering my own post, as I found a solution.
The HP servers (Proliant SL390s G7) apparently were unhappy about the
default localboot configuration, which is:
<code>
DEFAULT localhost
LABEL localhost
LOCALBOOT 0
</code>
The solution lies in the argument to "LOCALBOOT", and changing it to
"-1" works, so that the pxe config file reads:
<code>
DEFAULT localhost
LABEL localhost
LOCALBOOT -1
</code>
This is likely an issue with the HP BIOS.
Best,
Bjarne
