Subject: mvme5100 questions

I have some questions about MVME5100. As far as i know, if mvme5100 works as mater to control other hardware, it uses  VME_A**_MSTR_SIZEVME_A**_MSTR_BUSVME_A**_MSTR_LOCAL to realize address mapping. If mvme5100 works as slave to be controlled by other hardware, it uses
VME_A**_SLV_SIZEVME_A**_SLV_BUSVME_A**_SLV_LOCAL to realize address mapping.

But i don't understand how and when to use PCI_MSTR_MEM_  , PCI_MSTR_MEMIO_  , PCI_SLV_MEM_  ,PCI_SLV_MEMIO_ .If I use BLT by DMA, how does universe II and Hawk bridge realizes the address mapping step by step? And should I use PCI_MSTR_MEM_  , PCI_MSTR_MEMIO_  , PCI_SLV_MEM_  or PCI_SLV_MEMIO_ ?
