View Ref-File4  Virtual RAM                                             SCSI-Driver

When virtual RAM is present, the driver unfortunately is unable to 
establish the physical address of the memory to be transferred (the 
virtual drivers do not offer any information about this). A decision 
by the driver itself when the data are to be copied via a buffer to 
ST-RAM also doesn't seem sensible, as a separate buffer would have to 
be created for each process to avoid collision deadlocks. Therefore 
programs must themselves ensure that the memory to be transferred lies
in ST-RAM when virtual RAM is present (see also SCSILIB.H). Transfer 
for ACSI accesses via the FRB or the XFRB does not present any 
problems here.
