    When I do cat /etc/redhat-release, I got this.

    #CentOS release 5.5 (Final)
Red Hat Enterprise Linux Server 5.5 (Tikanga)

    It looks Red Hat Enterprise Linus is originated from CentOS. Anyway I want to use some linux personally which is familiar to me. How the CentOS is different with Red Hat distribution? Can I use it similar manner?

    You have it backwards; CentOS is derived from RedHat Enterprise Linux. From the CentOS website:

    CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.) CentOS is free.

    It is basically the exact same OS, with different branding logos, is free to download, and support is done through a community of users rather than via a paid support subscription.

    I have a one year old Mac Book Pro that I am trying to get RHEL 5.4 installed on via bootcamp. No matter what I do I can't get the installer to boot. I have tried multiple DVD's and even verified the install works on a new Mac Book Pro. Most of the time the installer simply locks up.

    I usually use Linux text with all-generic-ide on the boot line.

    I removed the ide parameter and I just used linux text. The results I get are that a bunch of kernel messages appear then the background turns blue and a thin text box pops up saying its loading ata..... something it disappears too fast for me to read. Then the machine freezes. I pressed the alt function keys to see if I could look at the system log, here is what it says:

    Alt-f3 says "trying to mount CD device hda" Alt-f4 says status error: hda: lastFailedSense Hda: Failed opcode was: unknown Hda: Lost interrupt Hda: Drive not ready for command Ide-cd: command 0x3 timed out

    Above this junk it looks like it found the partition because it knew it was 20 GB and listed as /dev/sda3. I think it has something to do with the CD drive, is that possible?

    Thanks again for the support.

    PS I posted in the apple support forums ( Apple.com > Support > Discussions > Boot Camp > Installation and Storage) and didn't get an answer.

    I pretty much followed this one when I first installed Linux on my MacBookPro (now a 1,5+ year old). The two big obstacles, as I remember it, were that it uses the UUID partition table and that I for some reason still can't get the machine to boot a 64-bit linux.

    Edit: I see now that he has a link to a bootcamp version of the article as well. I haven't tried that (didn't have a windows CD when doing it).
