Is there will be any guide for Win Svr 2008 ? Should there be installed and used MS MPIO.

BTW, if I make mistake and install MS MPIO support with MS iSCSI Initiator (ver. 2.8) onto 2003 R2 x64 can I only reinstall package or remove MPIO or I must rebuild server ? It is for testing purposes only as virtual server so there is no problem to reinstall it again.
