RiscPC, 2 MB VRAM, 256 DRAM, RISC-OS 3.7
>Description:
After double clicking the instKern, NetBSD runs up to the 
reality check. At this pointNetBSD is reporting:
 "reality check: No DRAM in this maschine? "

I suspect, that there is a problem with memory allocation
under NetBSD, as in this combination total memory is over 256 MB.
(Remember that there was such a similar problem with older
 PCPRO3 versions, what doesn't work with 256 DRAM on Risc PC's.

(Up to now I have not tried to test my theory
 by removing physically some DRAM. 
 I wan't to avoid it, as NetBSD should work as it is.
 / options passing trough the kernel does'nt work / )

Question: Was there really a check in the past, 
          if NetBSD runs fine on a 256 DRAM Maschine ?

kindly regards
