We have just bought a new server with Supermicro X9SCL-F motherboard for our backup server. This server comes with 2 NICs:

  • Intel 82579LM Gigabit
  • Intel 82574L Gigabit

Unfortunately, once the hypervisor installation completed, only one network interface is detected by VMware ESXi 5.0 which is Intel 82574L port. Since our architecture required to have 2 different cards so we can use it as fault tolerance to bring high availability features.

What we need to do is basically like this:

  1. Download the driver here: http://dl.dropbox.com/u/27246203/E1001E.tgz
  2. Use ESXi-Customizer to merge the driver and generate a new VMware installation ISO
  3. Burn the custom ISO into disk or USB drive
  4. Reinstall the server


Using ESXi-Customizer

1. Download it from here: http://esxi-customizer.googlecode.com/files/ESXi-Customizer-v2.7.1.exe

2. Double click on it and extract the files. Open the folder (ESXi-Customizer-v2.7.1) and double click at ESXi-Customizer.cmd

3. You will see following windows. Kindly enter required details as screenshot below:

Note: My installation ISO is VMware-VMvisor-Installer-5.0.0.update01-623860.x86_64

4. Click Run. The process will start and you will be see following prompt:

Just accept it by clicking “Yes”.

5. Once finished, you will find your new ISO as ESXi-5.x-Custom.iso. You will use this new ISO for VMware ESXi hypervisor installation.

After the installation finish, you can verify this using vSphere > host > Configuration > Network Adapters and you should see similar screenshot as below:

    Thank you very much my friend. Perfect.

    The CDs I create are not bootable. Does this app still work on 5.1?

  3. Braian87bNo Gravatar says:

    Do you know if its works on ESXi 5.1?
    I used this method http://virtual-drive.in/2012/11/16/enabling-intel-nic-82579lm-on-intel-s1200bt-under-esxi-5-1/

    but now the first (up) nic works more than 2x slower than second (down) nic. (using against a iSCSI on a NAS.)
    I already disabled DelayedAct (as I read on other forums)
