Hi guys,
I got it running on a 755 OptiPlex.
Pre-install:
- Go into the Bios and change the SATA operation to "Legacy"
- Enable Virtualization and VT for Direct I/O
- Disable NIC, the NIC on the mobo will not work
- Install a supported NIC. I installed an old HP 10/100 card for now. You can also buy a cheap, HP NC110T gbit card.
Reboot and insert the ESX CD. I used ESX 3.5 Update 1 (82663)
Install ESX and check if it loads and if you can open the website. Install the VI 2.5 and you will notice that you cannot create a datastore for the VM's.
Reboot the 755 and go into the Bios. Change the SATA operation to RAID Auto / ATA
Save changes, connect with VI to the ESX and you can now create a datastore. Create a datastore on the free disk space on the SATA disk. You can now create VM's!
I'm using a 755 DT with 8GB and a E6550 CPU. Again, you need another NIC as the other NIC is not supported by ESX.
