I just installed CentOS 4, and here are my initial findings.
I’ve been pretty impressed so far. CentOS is basically the same thing as Redhat Enterprise, so packages are compatible. CentOS uses yum instead of up2date, which makes me happy. yum is one of the most important things to happen to Redhat in recent times.
CentOS 4 includes kernel version 2.6.9-5.0.3.EL by default. The 2.6 kernel supposedly has performance advantages over 2.4, so I look forward to playing around and seeing if there is a big difference.
CentOS also ships with SELinux, but I disabled it because I’ve heard that it causes compatibility issues with many software packages.
I ran into a few problems during installation. Here’s the list of problems and how I fixed them. This installation was on a Dell Inspiron 600m with a Pentium M 1.6 GHz processor, but should apply to any Centrino laptop.
1) Intel PRO/Wireless 2200BG – ipw2200 – doesn’t work after install.
The driver for the ipw2200 was installed by default, but it didn’t work initially. I was able to trace the problem down to missing firmware. I’m guessing that they didn’t include it for legal reasons.
In order to get the ipw2200 working, you need to download the firmware from the Intel Pro/Wireless 2200GB SourceForge project. The version you need is v0.6-v0.16 firmware.
After downloading the file, type in the following commands as root:
tar -zxf ipw2200-fw-2.0.tgz
mv *.fw /lib/firmware/
Then, wait a few seconds, and type:
And you should be good to go! You may have to configure the interface, but I’ll assume for the moment that you know how to do that.
2) XMMS doesn’t have MP3 support.
Yes, if you’ve run Redhat anytime within the past few years, you know that Redhat doesn’t ship MP3 support with its operating systems. So, you need to download the package xmms-mp3. As of this writing I didn’t find a Enterprise 4 package, so I just used the Enterprise 3 package from rpm.pbone.net.
Just type in the following command as root after downloading:
rpm -ivh xmms-mp3-1.2.10-9.2.1.el3.rf.i386.rpm
3) No Microsoft fonts are included.
Unlike SUSE, Microsoft fonts are not included by default. So, what I did is download an RPM provided for Fedora Core 3 by mjmwired.net.
After downloading the RPM, type in the following commands as root:
rpm -ivh msttcorefonts-1.3-3.noarch.rpm
I hope this helps! I’ll continue to play around and update if I find any additional quirks.
