Proliant1600 Linux and 2nd PIII 500 processor doesn't work

Hello,

I seem to have an odd problem with my Proliant1600.
I have two PIII500 processors and I use biosP08 11/08/2000.
The BIOS says that two processsors are available but after booting Linux (SMP kernel 2.6) and a more /proc/cpuinfo I see only one processor......

I have tried another CPU-cage, other processors, I have tried another card-cabinet and I have tried an older BIOS, with following results:
-CPU cage, no difference
-Different CPU's made no difference
-Different card-cabinet (older BIOS)
The older BIOS with two PIII500 placed, says: "unsupported CPU detected, system halted"
After replacing them with dual PIII400 the system booted and I had two processors available in Linux.

How can it be that the system will not work with two PIII500's ??
Has anyone had simillar experience ?
How can I get my 2nd processor to work properly ?

Thnx,
Hans

Hans:

Have you tried setting the server to use APIC Full Table Mapped?

Go into the System Configuration Utility and hit "Ctrl A" for Advanced and set the APIC Table Mode. Then check the configuration if you can install the SMP Kernel.

Also, make sure the two PPM's or Processor Power Modules (a.k.a., VRM's) are the same Spare Part Number for the 500MHz processor. You may have installed different PPM's for the processors.
Enjoy!

YES !!!

Thnx a lot John, that did the trick !! :)
I wasn't aware of that "advanced menu" and would never had figured out how to get there without your help ! :)

Great, a more /proc/cpuinfo gives following:

John, one question popped in my mind as I was working on my DUAL processor Proliant ;)

Maybe you are aware of any particular BIOS setting or trick to reduce the fan(s) speed ?
They seem to blow max. rpm 24/7 and it's not the most silent machine around ;)

Just a question.... I'm already happy that I finally got the 2nd proc. to work ! 8-)

Thnx again,
Hans

Hans:

Yes, you can install the ProLiant Support Pack for Linux. What distro of Linux are you using?

There is also a way to do this, sort of, but I will say DO NOT do it unless you have this system in a Rack Mounted position. You can set SW1 S3 to ON to enable Rack Mount settings. This also will effect the fans but only after the Health Drivers are loaded.

Let me know what you are running and I will get you a link to the PSP?

Enjoy!
