Thanks for the link, and yes you are right it doesn't allow me to download it without support contract.
I need this to my home lab (I only have old HW available, what is not supported any newer ESXi versions)
so unfortunately support contract is not an option.
Any other suggestion to find free version of ESXi 4.1 U3 iso download would be much appreciated.
ps. I've installed and authorised Dell "version" of free ESXi 4.1 before, so I should have at least licence available on old Dell server installation if it agrees to boot anymore.
Thanks!
