Today i tried to install Debian 7 64-bit on a HP ProLiant ML350 G5 server and having problem with its network card firmware/driver not included with Debian 7 installation CD.
The driver for bnx2 was not included because it’s a non-free firmware/driver, hence i ended with Debian installation without network connection.
After a search on Google, i found another CD image on Debian website which contains non-free firmware/driver that you can find and download here: http://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/
