Do you still have a bootable IRIX image for your O2? If so, kick into swmgr and look to see if it lists the O2 prom update package as installed. I don't think it is part of the default install, but is on the overlays. Once you have that on the box, use swmgr to list the files in the package and locate any docs, man pages, etc...
RM5200 is a specific kernel target for the linux builds. -S- On Sat, 25 Aug 2007, Stuart Longland wrote:
Hi All... This isn't so much a Linux/MIPS related question, but rather an SGI one, anyway. I've recently purchased an RM5200 CPU module for my O2 (which presently runs a 180MHz R5000). I powered down the box, pulled the system board out, and swapped the CPU modules over. Upon doing this, I get a "Unsupported CPU type" message on serial console, and the box refuses to start. I figure this is because my PROM is too old to support the RM5200. Does anyone have any pointers regarding how one upgrades the PROM? (I still have both CPU modules.) Or am I up for a newer system board in order to benefit from the new CPU? Also, once I have the CPU going ... do I need to do anything special kernel-wise, or will my existing R5000 kernel work?
