Followup-To: poster Sender: logan@guild.org Lines: 27 I recently acquired a 1meg Memory Expansion Board for my Sun 2/50. This is the standard 9U VME type with the 6U socket on it for a SCSI/SKY board. It is replacing a zero-meg expansion board I was using before. However, my kernel (3.5) refuses to recognize the extra memory. When it boots, it displays the memory size as '4096K'. A kind soul sent me the appropriate jumper setting for the card, so I checked them out. When the board arrived, the jumper settings were: J2200 5-6 J2201 5-6, 9-10, 13-14 According to the instructions I was sent, J2200 should have been '3-4', so I changed it. That didn't help. Does anyone have any other ideas? Is there anything on the CPU board which needs to be changed to make this work? I've tried it with two separate 4meg CPU's, and neither worked. How about in the Kernel? I've booted with the GENERIC kernel, and that also didn't help. If anyone had ANY ideas, please let me know! It's very frustrating having an extra meg of RAM and not being able to use it.... Thanks, Scott Logan logan@guild.org We don't believe in miracles... we rely on them. logan@torag.uucp
