SMP Support

[Ayman Altounji]

I am running redhat 6.2 and installed 2.2.19-6.2.1smp kernel which is compiled for smp support. When I boot up and view messages file, I see the error "SMP motherboard not detected. Using dummy APIC emulation.".

Anyone have any suggestions

Cheers

Release: 6.0 6.1 6.2

Issue:

I've installed the Red Hat 6.0 on a Compaq 1600r with dual CPUs. After installation, I manually installed the SMP kernel via RPM with the version that came on the CD-ROM. The problem is that the kernel does not detect the SMP motherboard as shown in the dmesg result:

Checking 386/387 coupling... OK, FPU using exception 16 error reporting.
Checking 'hlt' instruction... OK.

SMP motherboard not detected. Using dummy APIC emulation.

Resolution:

In the BIOS you should find an OS type setting. You can select NT or Unixware and a couple of others. Make sure it is set to Unixware.
