QNX 6.4.1 dual core   
 Hello All ,

 When we install the qnx 6.4.1 os on an intel dual core processor ,
 would it by default use only one cpu or would it configure to take
 advantage of both CPU's . I have done just a regular install with type
 79 file system.

The pidin in  listing relevant o/p says

Processor1: 66222 Pentium III Stepping 10 2825MHz FPU

does that mean it is aware of only one cpu 

thanks
subra

By default the installation process install the single core version. To install the smp version cp /boot/fs/qnxsmpbase.
ifs /.boot

Re: RE: QNX 6.4.1 dual core   
I  did try that too ie copying /boot/fs/qnxbasesmp.if    /.boot .
My pidin in  out put remains same .
I know i am running a dual core .
So just by looking at pidin in output i am not able to say if  my os is taking advantage of all the cpu cores  or not .
Any other info is helpful .

thanks
subra

I assume you rebooted after you did that?  Maybe the second core is disable in the BIOS?

Re: QNX 6.4.1 dual core   
When copying .boot files like that remember to run sync before you 
reboot, especially on the qnx6 fs
