Hi all,
I bought new Lenovo G50-70, having good spec(core i7,1TB, 8GB RAM), thinking to install CentOS 7 for my RHCSA exam. But I ended up unable to install CentOS 7, the latest version.

It tries to boot but immediately it shows the below error:
Unknown hardware version aborting

Anyone having any suggestion is appreciated
Eyuel.

Give us a break. Tell us exactly what it does and when it does it from the moment you insert the install dvd and reboot. I'm not looking for half a mile of log. I want to know what worked, what stage of the boot things go wrong, and exactly what's happening there.

then please post the REQUIRED and needed information
the information YOU would use to solve the issue
( you are planning on testing for this )

"it dose not work"

is of no use


also as you know a laptop is not a server

so install in TEXT only mode
-- no GUI

Here is what I did and what I got from the beginning:
Booted from CentOS 7 DVD, and selected Install CentOS 7, then the below is what showed up under 4 penguins (linux logo):


[ 0.000000] Detected CPU family 6 model 69
[ 0.000000] Warning: Intel CPU model - this hardware has not undergone upstream testing. Please consult http://wiki.centos.org/FAQ for more information
[ 5.512791] psmouse serio1: elantech: unknown hardware version, aborting...

BTW: I have tested Ubuntu 14.04 and it was ok.

Thanks,

Kernel without psmouse support, see https://bugzilla.redhat.com/show_bug.cgi?id=969473.


It uses a different kernel.

"for my RHCSA exam"
you seam to be missing a bit of book learning
Cent moved to using mostly the RedHat documentation back when 6 came out
look on the RHEL hardware list
https://access.redhat.com/search/bro...ied-hardware#?

Did you check the hardware compatibility list ??????
RHEL/CentOS is MEANT for SERVERS
-- headless servers

then second the DESKTOP install in the Office on hardware ON the "compatibility list"
( as in IT bought hardware that IS on the list )

RHEL/Cent was never designed to run on a laptop

now
on SUPPORTED LAPTOP HARDWARE cent will run mostly fine
IF the hardware is supported NOT ALL hardware is supported


plug in a usb mouse and build a different kernel with the patch

Thank you for the reference, but I haven't checked compatibility because I never thought Linux would have incompatible devices. That was wrong assumption I had I think.

Ok, now I have wrong hardware version, I need CentOS on this device as it's the suggested release for my needs.

[/QUOTE]
I am not that good on Linux to build the kernel, but I will teach myself. I would be thankful if you share resourceful link, meanwhile I will google about it.

Regards,

You can run Centos for headless servers with your box. The incompatible bits won't work. If you want to have a gui, and all the bells & whistles you normally have
1. You are creating an unreal environment, as servers don't usually run GUIs.
2. You would be practising in an environment which is radically different from any practical exam.

Can you put Centos in a VM or as a dual boot option?

1. I needed the CentOS on Lenovo laptop, not on server.

Installation on VMWare was OK, but still no luck to install it as a dual boot, which is what I actually needed as my intention is to make CentOS host OS and install Redhat VMs.

I will try all possible ways to make CentOS installation lenovo G50-70 series possible, if not I will go Fedora or Opensuse.

Thanks for your professional inputs and suggestions.

I don't see a problem with that, unless you laptop is the problem
"No Lock" talls us nothing and get5s you nowhere near a fix. Details are what do that. What happens. I don't want half a mile of output, or 15 log files to wade through. I want succinct descriptions and snippets where and how things went wrong.

I'm running CentOS 7 on my laptop built from minimal that is not on the supported HW list. OP could install the ML kernel from ELrepo if he can get it minimally installed.

Lenovos are pretty much 100% compatible with Fedora. I'd assume that CentOS7 is no different...

The elantech touchpad is supposed to be supported in the kernel from version 3.2, but there seem to be a lot of people having trouble with it. The module has been recently patched (yet again), which is why Ubuntu (kernel 3.16) works and CentOS (3.10) doesn't.

This describes a change to the module source code that worked
http://mariusmonton.com/?p=489
If a CLI install doesn't check the touchpad (I don't know about that, as I've never done one), you could do a server-style installation; get the module code off the DVD, patch, compile, and install it; then install the rest of X and a GUI. Rather you than me, though.
