Processor Upgrade

[Ayman Altounji]

We have one Pentium Pro 200 CPU (512KB)in our Server. In Case we can not buy additional CPU from Compaq we found some CPU Pentium Pro 200 (1 M) original for Proliant 6500 or 7000. We try to use it in our 5000. When we use it as second CPU it got detected but with an error message (212 and 178). We tested to use two of them but system did not boot up. Is it possible to use one or more of this CPU in 5000. What are the needed steps to do this. Thanks in advance.

couple of things here...1) you CANNOT mix processors of different cache sizes so your 512kb and yout 1m ones together will not work..
IF you put two identical ones in that you know work then you will need to do the following.
1) you need to change your apic mode in your bios to full table instead of full table mapped..you can do this by Booting to your f10 partition, hit CTRL-A for advanced mode..choose the first menu option.. then choose the first menu option again..it will then say ?please wait loading configuration files? when it comes back from this choose review or modify hardware settings..then on the next menu choose view or edit details..scroll down the list to the advanced features section and in there you will find an option labeled APIC mode...change it to full table.
The next part depends on wether you are running NT or 2000..if NT you will need to bring the system up under one processor and do the following:
NT HAL ugrade
Adding additional processors to a server after NT is installed. None of this will be necessary if the system already had two processors working correctly and you are only adding more after that.
Install the new processor(s) as noted in the manual for the system itself or that comes with the chips.
Then configure the server hardware to the correct the "APIC Mode" settings. You must start System Configuration and press 'CTRL a' at the first menu after selecting F10 during boot. This activates "Advanced Mode". Then enter System Configuration itself and follow the prompts to complete a basic configuration load. Select to "Review" the settings and then pick "View/Edit Details" from the menu. Look down the list to find "APIC Mode". Press enter on this selection and select "Full Table, Mapped" (or "Full Table" if only choice, depends on specific system). Once this has been done, exit and save changes.
The next step is to load the Multiprocessor HAL on NT. This is best accomplished with the latest Compaq NT SSD (for 3.51 or 4.0 specifically) as this utility will do a more reliable job of identifying the correct HAL for the system. Simply run SETUP.EXE from the SSD disk 1 and select the HAL upgrade (you may also install other drivers if desired, do NOT force all drivers to load as some may not work on your system).
If 2000 then you will need to go to your device manager and under COMPUTER you will see ACPI uniprocessor hal..right click and choose properties..go to the drivers tab and change the driver by "selecting from list" to ACPI multiprocessor PC. then shutdown and install the second proc
You will ALSO need to update your rom to the latest rompaq to support the procs..which you can get at the following URL:

Hey Mark Cl

It seems that you are the man that knows a little about this topic, so I realy hope you can help me!

I have a Proliant 5000R with 4 PP200 an 400 Mb ram (and a Compaq StorageWaors), with Windows 2000.
I have done everything as described, but when I change from MPS Mulitprocessor (Windows can only find 2 CPUs) to ACPI Mulitprocessor, the system just hangs after reboot (when the white windows line has done loading)!!

What is wrong. I hope you (or someone else) can help me!

Please update the BIOS to the latest and greatest.
At POST does it see all processors??
Also in the F10 partition in Advanced Mode and make sure under APIC mode it says FULL TABLE MAPPED.
