Installation of IS 4.1 SP1 in distributed environment

Hello,

My server landsacpe is as below -

Server 1 - BOE 4.0 SP4, DS 4.1 SP1 APS services, DS 4.1 SP1Management Console 

Server 2 - Full DS 4.1 SP1 install

Server 3 - MS Sql server dataase

I was expecting to do a "Primary" install on Server 2 so that all my EIM components reside on the same box along with DQ cleansing packages, but since it does not have any BI or IPS installed, install is getting errored out. I really doesn't want to do primary install of IS on Server 1, becasue that will also require installing DS 4.1 SP1 Job server component on that server.

So what are my options in this case?

Thank you,

Vimal Shah
