ok. I dont understand this. My gvp seriesII memory is
0x200000 - 0x5fffff. Normally in AmigaDos and NetBSD it
doesnt have the 24BITDMA bit set. When I boot up NetBSD I
get bounce buffer pa as 0xd301c. This is in the chipmem right?
Ok. So I figure I'll force my memory to be 24BITDMA. In
loadbsd I set the 24BITDMA flag manually for the segment
0x200000 - 0x5fffff. I can boot NetBSD fine with this
setup, everything seems to work. Now the bounce buffer appears
at 0xd6c000. What confuses me is that this address isnt in
any of my memory segments!
