[CentOS] Intel DG33BU motherboard

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 Google
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?

TIA
