I am using a Leveno M58 (model CTO7483 from 2008) for C6/7 experimentation purposes. The thing has a dual core and ~4Gb RAM with a (newly installed) 500GB HDD. I successfully installed CentOS-6.5-minimal from a freshly burned, and verified, DVD from and ISO image whose SHA has been checked and passed. everything about the display was normal throughout that process.
When the system boots from disk then I get the normal display up to the point that the kernel is selected (whether by hand or automatically). I can edit the kernel command line and otherwise use the pre-boot selector facility. After that point the monitor, a BenQ 17" LCD, immediate goes into what I can only describe as a psychedelic snow field with two narrow black bands surrounding a broader white band displayed at the top of the screen and a single narrower black band at the bottom.
I have tried booting into RL3 by appending a 3 to the end of the kernel command but this has not apparent effect on the outcome.
Any suggestions on how to proceed?

boot to single user, and edit /etc/inittab and change this line...
id:5:initdefault: to id:3:initdefault:
and reboot.

1. What video manufacturer? Nvidia? Ati?...? 2. Bring it up in runlevel 3, and see if that happens. If so, create or modify /etc/X11/xorg.conf by hand, and try to force it to use either the VESA driver, or whichever goolging tells you supports your video. Remember, startx is your friend.... 3. You might want to add nomodeset on your kernel command line in grub.conf.

I have no idea. But in opening the case to find out I realized that the video feed was attached to a PCI card - whose manufacturer escapes my attempts to identify. In any case, removing that card and attaching the monitor to the built-in video solved the problem.
Thanks,

AUGH! That was *not* what I meant. Can you get it up, at least in singleuser mode? If so, lspci will probably tell you. Or lshw. Or dmidecode... or, for that matter, it might tell you in dmesg or messages.

I understood what you wrote. But as I pointed out in my first message on this subject I had already specified RL3 on the kernel command line and that did not change the behaviour. So, no I cannot get the system up to the point that I can run anything, or at least see whatever output is created by whatever I might be able to run.
But, as this is an experiment box I do not need a dedicated graphics card in it. So, having been prompted the open the case to discover the make of video card, I tried the (to me) obvious course of action to simplify things. Which worked to the extent I require.
The removed video card looks like some sort of oem job with no obvious (to me) brand or manufacturer markings. I cannot tell the chip maker because the processor is covered by a fan and heat sink. It is a half-height, full-length PCI card with a marking that looks like a V followed by two 'C's one inside the other, followed by an I. The word TOPSEARCH is also present.
