Hi, trying to setup ESX 3.5 on subj machine.
ESX ISO loaded, started initialixation and when "Initializing processors" I'm getting "PSOD" (pink screen of death) ;-).
Already searched though discussions but failed to find anything.
It should work.
Be sure that your processor is supported, that you have a valid NIC card, that your CD is in "IDE" mode...
Have you tried with ESXi 4.0?
by running ESX 3.5 on a Dell Optiplex I will assume you are going to use it for your training. Why don't you put some more RAM on it and install ESX Server inside VMware workstation.
If you have enough resources you can install two or three ESX Servers and them setup a VMware Cluster.
It's just a suggestion.
