Hi,
The images you attached show a pcbios boot that tries to use undionly,
which should be undionly.kpxe
You could try to to add the relevant PCI_ROM line into tg3.c and then build
and use ipxe.pxe instead. However there have been some other known issues
with that driver.

I would instead investigate why the undionly driver is failing, it is
supplied via the BIOS, so might be a bug there. No update available for the
BIOS?
Your PXE stack does load iPXE so the network is clearly working, but it
might be an issue with state of the NIC
(in some cases we have seen nics that work after a coold boot, but not
after restart for example), It could also be link speed, for example
100Mbit link does not work, but 1Gig does.
All these are of course bugs, but undionly is and have been stable for a
long time, so that is why I'm at first suspecting issues with the BIOS UNDI
implementation rather than iPXE.

It might be possible to get this machine working with a tg3 enabled build,
but it would be good to also resolve the undionly issue, since that should
work on all machines regardless.

To add 14ee to the driver copy one of the lines at
https://github.com/ipxe/ipxe/blob/master/src/drivers/net/tg3/tg3.c#L875 and
modify it to have 14e4:16ee instead, and then build either tg3.pxe or
ipxe.pxe and upload to your tftp server and point your dhcp server to it
