Thx, I was having an issue with my credentials but has been resolved. I was able to access the downloads on their website, etc. and have gotten the ISO.
My problem was that I had downloaded the Dell version and I was using the VMware checksum and was paranoid that I had gotten a bad ISO. I was looking for a 3rd party ISO because I wanted it to match up to the checksums on the VM site.
Sorry for posting here - I was in a bind and it was late at night and wasn't able to just call tech support or my rep and get it resolved.
moderators please feel free to delete.
if this ends up sticking around then if anyone finds this in the future:
(obviously) the dell esxi 5 iso does not match the vmware iso's checksum and vice-a-versa.
