CentoOS memory crash

I have been having problems installing CentOS version 5 from a live CD.

Upon boot up I receive the message,

"Memory for crash kernel (0x to 0x) not within permissible range"

Now, I have gone through the troubleshooting steps at:

but the only thing that references this is error is this quote:
"During the boot process you may see the message "Memory for crash kernel (0x0 to 0x0) notwithin permissible range" appear. This message comes from the new kdump infrastructure. It is a harmless message and can be safely ignored."
I can't ignore this because when I receive this message, the computer is unresponsive. Nothing happens when I hit escape, tab, enter, or any key at all.

I have googled this message without anything definiitive as to what to do or how to "ignore" this error.

Has anyone had this same issue?

I've not seen it myself (other than being able to ignore it). You may want to see if you can modify the kernel line at the boot prompt and just remove the kdump portion that allocates X amount of memory if it is not something that you want/need.

it will probably look something like:

I seem to be able to boot when I add the line "noapic" to the end of the kernel, so the kernel statement looks like this:

vmlinuz0 initrd=initrd0.img root=CDLABEL=CentoOS-5.1-i386-LiveCD rootfstype=iso9660 ro quiet liveimg noapic

However, this is a live CD, and although I can boot up CentOS, I don't see how to install it. The Fedora 8 Live CD had an Install icon. I can't find an executable script that launches the install proces for the CentOS live CD.
