Installing 32-bit Server 2003 R2 Std on 64-bits Powderedge R710

Hi,

As per the subject, I need to downgrade a new PowerEdge R710 64-bit Server 2008 to a 32-bit Server 2003 R2 Std version. So would be the right way of doing it?

So far, I've only tried booting up from the OEM disc of the Server 2003 but unable to install due to "No hard drives presently" error.

Could anyone advise any things? Thanks.

Cheer,

Irvin
