How to get hardware information through ESXi console

For an assignment I was asked to get info on how memory have been plugged into ESXi host.

My colleague who is a Linux maestro said there is a command to get hardware level information.

# dmidecode | less

The above command works for ESX 3 to 4 versions as it comes with a service console.

But the command has been replaced with ESXi 4 onwards.

# smbiosDump | less
