How to disable a CPU in a dual PII?

Stefan Suter — Fri, 21 Feb 2003 23:36:12 GMT

Netserver LPr has dual PII 450Mhz. Due to application does not support dual CPU, need to disable one of two CPU. Application is a IVR and runs on UnixWare 7.1.1. BIOS doesn't show an option. How and where can this be done?

you can shut down machine unplug and remove the second processor and reboot the bios should recognize just one processor and boot fine

Is there no way to install a uniprocessor kernel ???

This is coming from a Windows 2000 background where you simply downgrade the HAL - Hardware Extraction layer.

Hans : you don't even have to touch your HAL. With NT/Win2K, you have just to append "/onecpu" at this end of the line in "boot.ini"
The fastest way to troubleshot a problem.

Back to UnixWare : I believe that you can simply remove the "osmp" package ("multiprocessor support") using "pkgadd".
You *may* have to reinstall all the patches (not sure)
