Broadcom network card drivers
[ source: The Broadcom BCM57781, ASRock Z77 Extreme 4, and You ]
- Download the broadcom driver (vmware download) or broadcom driver (local download).
- Download ESXi-Customizer.
- Run ESXi-Customizer.cmd, select the ESXi iso you’d like to modify (instructions are for 5.0 u1 but 5.1 works also), the broadcom driver zip and save the iso.
- Use unetbootin to create the bootable usb key
After you run through the ESXi install, if you have a DHCP server on the network, you’ll now get an IP assignment.
