Except that this doesn't appear to support embedding a menu file, and I'm not sure whether this method supports HTTP image loading. Maybe I'm not building it properly.

Seems unlikely. Nearly every other bit of hardware in our environment works with this setup. Pretty much anything with an Intel NIC works fine. It's just this new HP laptop model, with a brand-new Broadcom NIC, that is not working. And it seems pretty obvious that the problem is that the bootloader doesn't recognize the NIC (no valid driver).

I am not sure what this would do differently. Building a bootloader that is specific to the NIC in this laptop isn't very useful (we need a bootloader that works across the whole fleet, not just this one model). And I have no idea what I'd do with a .lkrn file...?

Yes that's the latest one, goodie ;)

>>> Why kkpxe?
> We have a standard infrastructure based on pxelinux, so we are chain-loading iPXE specifically for Windows installs. Linux and ESX installs go through our standard pxelinux stuff. But it all has to live on the same network, so pxelinux is the "primary" bootloader.
> I did not develop the ipxe setup for Windows -- it was handed to me in this state. I don't know why we use kkpxe versus other types of bootloaders, except for "that's how it was set up". Is there a better way to get HTTP-based image downloads to work without needing kkpxe?
Ok yes, use undionly.kpxe (single k) that should work for all nics
that are chained (unless The underlaying UNDI implementation is buggy)
Having pxelinux in the boot path is sometimes causing an issue so you
should try without it, for example by building the .usb version
instead and booting directly from a usb stick.
I'm guessing here, but kkpxe might actually be part of your issue.
> The key feature of ipxe that we're taking advantage of is its ability to use HTTP to retrieve a disk image, rather than TFTP. With Windows installs, we have to download a multi-hundred-MB image, which takes FOREVER over TFTP. Over HTTP it is much faster and more reliable (since it uses TCP instead of UDP).

It was a one time build and was never sent upstream. (I'm just a iPXE
user like yourself)

What did you build? please try: make bin/14e41687.pxe DEBUG=tg3
Or if you chain from pxelinux you might want make bin/14e41687.lkrn
undionly versions will never include specific nic versions, so it
won't make any difference.
