[rescue] Sun Netra T1125

Hi Mike

So the CPU is rated at 480Mhz....so by clocking at 480Mhz I am picking I am not stressing the CPU. Is the UDB chip on the CPU or off board? Will see if I can find SunVTS to stress test though....

As far as I can tell I am running the latest OBP 3.31 for netra t 1125.... per the following link http://www.imhans.com:1004/syshbk/Devices/Boot_PROM/BootPROM_UltraSPARC_I_II.html#U60 

As to the CPU1 issue if I use it as CPU0 I get a (RSE) Red State Exception which as far as I understand is a hardware error....anyone got a spare ?

have identified that issuing the command "word" at the obp will list all the available commands.....yet to try it though...

That being said rather happy with the outcome...

cheers

Richard
