Probably only the install-time card is marked as boot-start.  The easiest way 
to mark all cards as boot-start is to install sanbootconf:

iPXE doesn't support MPIO/MCS, but the Windows initiator should support them.  
On earlier versions, I seem to remember MPIO being an option that had to be 
enabled at the time of installing the iSCSI initiator; not sure how that will 
map to Windows 7, where it's pre-installed.

BTW,  please consider upgrading to iPXE (http://ipxe.org), since it is 
actively maintained.
