[ipxe-devel] Running into problems with Broadcom NICs (14e4-1681 and 14e4-1687)

[Jeremy Mlazovsky]

An update on this for anyone out there who is listening.

My colleague has been troubleshooting these issues this past week and he
discovered that HP makes available on their drivers web site a firmware
update for the Broadcom BCM5761 NIC that is embedded into the HP 6305 small
form factor desktop.  The firmware update can be found at
http://h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=5311951&swItemId=vc_131810_1&swEnvOid=4158
.  After installing the firmware update for the Broadcom BCM5761 , the HP
6305 desktop is able to communicate on the network properly using iPXE.
So, the good news is that we have a proper fix in place now for that NIC
(14e4-1681) .

It does not appear that HP is providing any Broadcom firmware updates for
the HP 705 G1 but we will keep investigating this.
