Hi Dave
for the record.. the module of interest is DOSFS .. SCSIFS purely
provides a filecore based filing system, and if the image found isn't
filecore it is 'offered around' to other modules and DOSFS claims it.
it then uses, in effect, the scsifs drivers for block/sector access.
What happens when a drive with a >2GB partition is offered around?
Does it become available for block/sector access via FileCore%SCSI?
if memory serves: it is treated as if it is a single file .. hence the
(current) 2gb filecore file size restriction 'gets in the way' I don't
remember any attempt to trap this situation..
various strategies have been considered, varying from allowing dosfs to
have direct disc access in cases where it is happy it is 'talking' to a
disc, not a file on disc, to a system that 'slices' the dos disc image
into a sequence of 'small enough' files, much as cdvdburn does for dvd
iso images.
