In fact , I am moving from VME bus to CompactPCI bus . I have used your VME
bus drivers for MVME2600 and it is very good . Thank you very much. Does you
meaning there is  a similar driver for DEC21154(MCP750) so that 'open'
'close' 'mmap' and so on can be done on C-PCI just like your VME bus
drivers?
