Yes this fixed it. Thanks,
I have attached a diff to current that has your fix and a new feature in
the BOOTP code. I have created a kernel config option:
options "BOOTP_WIRED_TO=fxp0" # Use interface fxp0 for BOOTP
This is useful in a machine that has multiple ethernet cards and the
first card detected is not the card that was used for BOOTP.
