Error after installing ESXi 3.5 on Dell Optiplex 755

I am fairly new to this technology however I have been successful installing this software on servers but I am now having problems installing this software on a desktop. The desktop I am using I successfully installed ESXi 4.0 onto and it worked great however you need to purchase vShpere in order to manage the VM's after 60 days so I chose to go to 3.5 which has a free management console.

Now my problem, when I install 3.5 on my Dell Optiplex 755 it installs correctly but I get LVMDriver Failed to load. Now, I looked on the net for a solution to this but all the solutions apply to 4.0 and not 3.5. The KB's say it is because the NIC card is unsupported yet it worked just fine in 4.0. How do I fix this problem without going out and getting a second NIC card?

Just because it worked for v.4, doesn't mean it will for v. 3.5. VMware's HCL is the explicit resource for hardware/system compatibility:

The Optiplex isn't even listed when doing a query on DELL systems, whether v.3.5 or 4. That isn't to say it won't install, it just means it wasn't officially tested by VMware. That being said, it looks like ESXi 3.5 isn't able to be installed on your system.

ESX 4.0 has a large variety of drivers.  3.5 since initial release as 3.0 has drivers for a very limited group of hardware only including server hardware from the main manufacturers. with 4.0 they wanted to allow a wider variety of hardware to support almost any server, and some of those drivers cover components of Dell desktops because those same hardware components are in their servers

I have given both of you points because you both are right. I have done some further research and have found that if I add a know NIC card to this machine 3.5 works. It look like 3.5 just doesn't have the drivers for the embedded NIC card on the board.
