I am sure $1 was "build-dep".

As you suspect later, debian/rules file is the place to set your stuff.

You are looking for "pxegrub" file which gets crated just fine
at /lib/grub/i386-pc/pxegrub of grub_0.95+cvs20040624-17_i386.deb, that
I have just built with your options, netbooting on eepro100 card.

You meticulously examine the build outputs to find what you're looking
for. It is there.

At the very worst case, you examine the Makefile and trace the netboot
variables. "grep -rin <x> ." is your friend.

It *may* be that the ./configure option for your particular card would
be omitted from setting including the netboot section in the makefile. I
very very much doubt it, I think the Makefile.in is generated using the
rules file and unholy magic, not written by a human (or even a Debian
developer).

Principle fine, attention to detail.

But I very much liked this post, a nice grub + debian question gets an
answer from me even at this crazy hour.
