I just downloaded the ESX 3.0.1 .iso file. It says that it is a bootable file. Once I put it into my Dell 1950 server. It does not boot up to the menu for VMware. Is there anything else that I can try, so I can load ESX 3.0.1 on to this server?
You'll have to burn the ISO to a CD as a CD image and not as a file. If you open the CD on the host which you burned it, if you only see the ISO then in hasn't been burned properly. You can use tools like Nero to burn the ISO as a CD image or something like this is free (work on Windows) -
