Hi all. I am looking to upgrade my late model Octane from its SE graphics to V6 graphics. I have the following:
- Xbox 1.4
- PROM 4.17
- IRIX 6.5.22f
- Cherokee power supply
- R12000 400MHz

As I thought those were meeting all the prerequisites, I removed the SE card and put in the V6 card. 

After powering on, I get proper video, but during "running diagnostics", I get a red light. After the diagnostics are done, the light goes back to white. I get the "starting up the system" message, but the screen appears to freeze after that -- though I can see the HD light going, which leads me to believe it's continuing with the boot, but the graphics just get immediately frozen.

Thoughts on what to try next? Is there more info to get during that diagnostics at startup via serial port? Am I potentially missing software that's not installed? Or does this possibly sound like a h/w issue with the V6 board?

I went into the maintenance menu, ran the diagnostics there, and it didn't say anything of interest, other than it was unable to test Odyssey graphics and to use a cmd line tool.

After the machine potentially boots, I hit the power button, the red and white light start alternately flashing, which then leads to a shutdown/power down.

Much appreciate any help you can offer!   Jesse
