2. CentOS-5
2.1. Installation
It is necessary to boot with the acpi=off option for the kernel. If you don't, you will get an Oops at bootup. The install works as normal, but you won't see the second CPU while ACPI is turned off. Once you are booted into CentOS, a custom kernel can get you up and running with two cpu's.

2.2.1. Wireless
- Download the [javascript:void(0);/*1264295105514*/ Broadcom 802.11 Linux STA driver] and unpack it somewhere.
- Edit the file src/include/typedefs.h and change the following lines:
#if (LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 19)) #define TYPEDEF_BOOL #endif
and change to:
#if (LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 18)) #define TYPEDEF_BOOL #endif
- Build the driver (make) and install it (sudo make install)
- Run /sbin/depmod -a to get the driver registered correctly.
Run /etc/chkconfig --level 2345 NetworkManager on
- Reboot
- Configure your wireless with the network manager applet in gnome.
