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 Paolo -------------- next part -------------- An HTML attachment was scrubbed...
