a question about ipxe boot for imac a1419

It does seem like the link-up message is received on the Broadcom card, so something seems to be working. You'll have to step through all the steps listed in http://ipxe.org/dev/driver and notify us which of them fail. You might also need to build with debug activated for the tg3 driver to see more of what's happening. Once you have all this debug information you should get in touch with the developers on the mailing-list. It seems that the imac broadcom card is not working properly, and one of the developers will need to debug it further.

iPXE is a totally separate system from Linux, and downloading the linux drivers from broadcom.com won't help you at all. The only thing they're useful for is hardware documentation.
