Hi Peter
I tried that and it the result is the same: Linux only finds, initializes and uses only 1 core ... :-( Is there anything else I can try to have Linux initialize all 4 cores?
-- TIA Paolo

Hi
I've installed CentOS 5.2 (i386) in a computer with a DG33BU
motherboard
... When I installed it it crashed because of ACPI issues. Searching
I found that I need to turn ACPI off in order to successfully install CentOS, which I did. After a while I noticed that because of ACPI is off the Linux kernel finds, initializes and uses only 1 CPU core in the Q6600 quad core CPU
that
is installed in this computer :-( How can I force it to find, initialize and use all the 4 cores in the computer even if ACPI is off?
Try to leave ACPI on and boot with "pci=nommconf" instead. This works on my DG33 (mine is a TL not a BU though).
