<div> <span style="font-family:Calibri;font-size:11pt">I have
added new
pass through device to the VirtualBox setup . Registered all
6 BAR's with

address regions with
the sizes I have registered them with.</span></div>

Can you provide more details (how you map the regions initially and
on remap)? Hard to say what's happening otherwise.<br>

fundamental
problem is, I have been able to access BAR0 and NOT BAR5. I
tried playing with
BIOSmmio address setting in DevPciIch9, that made difference
in relocating
BAR's but functionality remained the same (Not able to access
BAR5)</p>

part is,
PIIX3 chipset is fully functional ie., can access BAR5 in
PIIX3 but NOT in
ICH9. <br>

Could be that with PIIX3 there's no remap and with ICH9 there's a
remap... really difficult to say anything with the sparse
information.<br>
