  • Topic: core2duo 2.4 GHz detection problem
  • SDP: 6.4.1
  • Target: x86

Question
________________________________________________________________________

QNX 6.4.1 just detects one CPU on an Intel E6600 based x86 system.

Recommendation
________________________________________________________________________

- Update the BIOS. The QNX startup use the ACPI tables to determine the number of CPU's in the system. If the BIOS haven't done this properly then QNX may just run on one CPU.

- Enabling APIC Support in the BIOS sometimes fixes the problem.
