CentOS - Nov 2008 - I need help with CentOS installation on a Core 2 Duo Laptop

Hi,

 I've tried to install CentOS 5.2 on Core 2 Duo T5750 2.0Ghz laptop
but what happens is every thing hangs up when anconda system installer
starts. So I tried PCLinuxOS in it's text-based installer it detects
the CPU core 1 and when it try to detected the other one system gets
stuck. I tried these same two distro's  on another PC that have a AMD
X2 CPU on this PC I didn't had that problem everything went smoothly.

Thank you

Try installing with "linux acpi=off" (as the kernel command line for
syslinux).

The kernel which gets installed should be able to handle the system
after installation, the installer kernel sometimes has a few problems.

Cheers,

Ralph

Also the following option might be necessary: pci=nommconf

That is, for example
    linux acpi=off pci=nommconf

Probably a shot in the dark but, try linux pci=nommconf  without the
acpi=off.

Fingers crossed...
