2. CentOS-5

2.1. Preparation

The hard drive is easily accessed by removing two screws holding a small cover. Pulling a plastic tab removes the drive. The original was replaced with a 250 GB Western Digital Scorpio Blue for a clean install.

2.2. Installation

CentOS was installed from the 6-CD set (kernel-2.6.18-92.el5) using the graphic-based installer. Although more than 512 MB of memory is recommended to use the GUI, it worked fine.

Disk partitioning was left at default.

Network Devices were set for automatic DHCP and for eth0 to be activated at boot-up.

Software selections included Gnome and KDE desktops and the expected basics for laptop use. No development items nor servers except Printing Support and Network servers. Virtualization, Clustering and Cluster Storage were also skipped. Both SELinux and Firewall were set to be active.

During the install the screen resolution was off, the NEXT button was not visible. However, pressing F-12 advanced the process along. Things like date, time and time zone didn't get set properly. But nothing was missed that couldn't be easily fixed later.

Only the first four CDs were required. The fourth one was in the drive just a few seconds before the DONE message appeared.

2.3. Post-installation notes

Rebooting took 1 minute and 35 seconds from Power-ON to the Login screen. On the way up there was a message about "Network manager could not find some resources." That message was ignored and it has never repeated. The assumption is that it was related to the wireless LAN not working initially. First login was as root for doing updates and any other core chores that might be needed. Right away the Update Manager announced that there were 284 package updates available. During the updating about two dozen dependences required updates also. When it was done the kernel had advanced from 2.6.18-92 to 2.6.18-194.11.1. KDiskFree reports using less than 10 percent of the 250 GB hard drive.

2.3.1. Wireless LAN Problem

The RT2500 chip was not supported in the current kernel nor in the base rpms. There is support for it from the ELRepo Project. The steps for getting it were to add the repository and install the proper driver from it.

rpm -Uvh http://elrepo.org/elrepo-release-5-2.el5.elrepo.noarch.rpm

rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org

yum --enablerepo=elrepo install rt73usb-firmware

Additionally, Network and Wpa_supplicant services were disabled and Network Manager was enabled through the KDE GUI at Administration > Server Settings > Services. The Network Manager allows connecting to whatever network source is available at the time. It is handy for moving from one network to another, especially wireless.

2.4. Issues

There were no continuing issues after getting the wireless LAN working. This laptop is not used for gaming nor heavy multimedia. It's main functions are E-Mail, web browsing, saving travel pictures until they can be transfered to a desktop machine and writing.

2.5. Models tested

Although called the 5400 Series, there are no subtypes.

It is difficult to nail down good resources for RaLink RT2500 material relating to the CentOS kernel. There are good sources such as The RaLink Project at http://rt2x00.serialmonkey.com/wiki/index.php/Main_Page. Unfortunately, they focus on later kernels as found in Fedora, etc.
