<> Hmmm, what if said 2000 is part of a cluster and boots off a cluster disk <> would you then be able to use a SCSI disk as a swap disk? < < I see not why not. Swap/page is just data. Booting is the only <limitation of which I'm aware. Only one way to find out. Doing that you would MOP boot from a cluster member then install the extendded page and swap for the local disk. If all your doing is that then any drive over 20mb (but not ST225 or 251 as they are slow!) will do in the MFM slot. In the past I've found RD52s (quantum D540 30mb) are a good choice for that service as they are fast and bullet proof. Allison
