Ok so you use the ipxe variant, which will indeed be buggy in some
circumstances if build with kpxe or kkpxe
Simply don't use ipxe.kkpxe or ipxe.kpxe , Can't stress this enugh
since it makes no sense at all to keep the old UNDI or PXE stack
available when having native support.
Use ipxe.pxe, or ipxe.lkrn
it is quite unnecessary to build everything so you would save quite
som buildtime if you add the specific target you want.

This (ipxe.*) will only support the drivers built into ipxe, what is
the ipxe output when running this build?

undionly.kpxe (using the UNDI stack, NOT PXE stack) however should
support all nics, but maybe not with native speed.

To test this you should add a _temporary_ menu item to your pxelinux
menu or as explained earlier build a .usb version that you test from a
usb stick, see previous links.


Just to be clear, what I'm suggesting might not, and in some cases
should not be the final solution, but should be done to figure out
what the final solution is.
If you don't have a system where you can test this (for example can
only test in production) then I highly suggest you start with a test
system for any future issues. (the USB version can be used as a
minimal test system)

>> 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).
