Hello 
I received recently a brand new pc, it comes with brand new hardware. The motherboard is MSI B85-G83 http://fr.msi.com/product/mb/B85-G43.html#hero-overview .
Is there something important i shall do in order to install properly from the dvd of openSUSE 13.2 ?
What are the options that i need to check in the new Bios ?
e.g :
Shall i update the Bios 1st of all ?
Shall i change some options in the MBās UEFI āBiosā or is it ok to install as it is ?
Thanks
If you are not going to dual boot yes update BIOS first. It can be a pain if the manufacture does not offer a bootable BIOS update. and requires Windows.
I assume this an EFI machine it being new So be sure to boot the instal DVD in EFI mode.
Even if you turn safe boot off check the safe boot box it will do no harm and if you decide to turn safe boot on again it will be all set
If dual booting with Windows 8.X then turn off fast boot in Windows.
Thatās it off the op of my head
Note that some Name brand machine EFI BIOS just donāt like to not boot Windows and will change boot back to Windows no matter what there is a work around but the MSI MB should be ok
hello
Iām not going to use dual boot, only openSUSE 13.2. Iām glad as i saw that Bios is already in the last version available.
What is the āEFI modeā in the DVD, where is this set ?
Safe boot : is this mandatory to turn this off ? I did not see where this is done in the Bios.
Another question about RAM and install :
i have 8 GB of RAM available, the Bios sees 8 GB but the i686 live cd only sees 4 GB 
The x86_64 live cd sees 8 GB or RAM.
Iām used to the x86 OS (i686) and would like to keep this as usual if possible, but itās be too bad if i loose 4 GB of Ram.
Is there a way i can benefit of my 8 GB using the i686 dvd to install ? (eg : My last motherboard had an option enabling all the ram to be seen by the OS but i canāt find yet in is this new motherboard)
If i install with the x86_64 dvd erasing everything but /home : will i keep my usual settings regarding softwares configuration ? ( thunderbirdā¦)
Thanks
btw : Happy Christmas and Best wishes 
When you boot an EFI system you have a short time to select a boot option form the BIOS boot screen Which key is hardware dependent but should be shown on the screen. pressing it will get you to a boot option menu. Select EFI mode to boot the DVD or USB stick you are using to install. If you donāt there is a chance it will think the DVD or USB is a msdos/mbr based device and boot into the old mbr (legacy) mode and the install will be MBR. IMO it is better to bite the bullet and move to EFI booting since that is going to be the standard for the foreseeable future. The really important thing is that you donāt mix modes if multi-booting . If you want to stick to legacy mbr mode it is ok if a single OS is used or if all are installed that way.

With this motherboard āDelā allows to enter the Bios. Do you mean that from the Bios options i need to pick up an āEFI bootā option or is it something before entering the Bios youāre talking about ?
I saw an entry giving me an option between āefi and legacyā or āefi onlyā mode but iām not sure if it is the same option youāre talking about .
No it is not the del it is special boot menu F10 or maybe F12 But who knows it could be an other key, should show on the boot screen. Since it a name brand and Dell to boot it could be that it will want to boot to Window no matter what if installed EFI and Windows files are still in the efi Boot partition. You never can tell but I believe that some DELL models do it. Also it comes with Windows so things are set up for Windows. You will have to zap the Windows partitions. If installing in legacy then also remove the efi boot partition (a small FAT formatted one)
It is a much better chance to to have a truly standerd EFI BIOS in a generic mother board the manufacturers tend to screw around with the standard. The main BIOS allows you to set the standard boot but the special boot menu lets you change the boot mode on the fly. Maybe a call to DELL support is called for if you canāt find the BIOS docs on line for that machine.
Somewhere in the BIOS, there should be an option to display the boot options during POST. How this is named or arranged is dependent on the particular BIOS on your Motherboard. You might even have an option to display the manufacturer logo at boot, if so turn that off and look for that additional setting.
When you cold boot, you should see something along the lines of:
Press XXX for BIOS Settings Press XXX for Boot Options (or, maybe, Boot Device List)
hi,
ok i saw this :
delete is to enter the bios settings, the 2d part i did not see it yet
i also so the part that allows to have the Msi logo so iāll look for this other setting.
Hi !
I would not recommend to do this, unless you have real problems running the pc.
A BIOS update always bears the risks that
(i) the update may fail and that youāre left with an unusable system,
(ii) the system performs worse or has more bugs after the update.
First try to install openSUSE and see how it works!
Good luck

Problem with that is that many BIOS updates are today packaged as Windows programs. If you donāt dual boot you can not upgrade. As A general rule I agree but because of the Windows orientation you either have to dual boot or you are out of luck and may have to installe Windows again to just update the BIOS. then often the BIOS is set to Windows oriented defaults when done. So I say do the updates while you still have a chance. Note some updates do come in DOS bootable images. But it truly is a crapeshoot
Solution?
Keep one of your small old drives around (I keep a few, IDE, SATA, and of course laptop internal) with a version of Windows installed, XP or newer.
It does not matter if it is no longer getting security updates. You just need to pop it in for a few minutes to run things like a BIOS update.
To Manchette_fr:
I have my system set for the Boot Device to be UEFI and Legacy. I feel I may want to boot DVD disk that is not UEFI.
As far as Secure Boot, my system gives me the choice between Windows and Other OS. Other OS in not secure boot.
Understand, Physical access to my machine is absolutely not a concern. Therefore, neither is secure boot.
To Fraser_Bell:
I donāt know if all systems are like mine. I have an ASUS Sabertooth motherboard. It has an AMI bios that contains an ASUS UEFI program as control. I does have one weirdness: If a drive that is listed in the nvram of the bios becomes unavailable during boot (like if I pulled the plug and installed a Windows drive), the BIOS will rewrite that nvram to defaults. This means that if I were to do as you suggest, when I reconnected the original drive, it will no longer boot! It wonāt even be shown in the BIOS screen as an option to boot!
You may want to read a post I made a while ago: https://forums.opensuse.org/showthread.php/498305-Some-Things-I-Found that sort of explains what I found.

My advise is to take a deep breath and go pure EFI or pure MBR. The hybrid thing seldom works and can bite you at latter time out of the blue. Windows 7 supports EFI boot just not secure boot. For the amount of trouble it gives secure boot gives dubious protection IMHO
I agree with you that it could break somthing in the process, i 'm lucky as my motherboard already has 3.9 which is last version of the Bios. I was asking for i read many times that Bios should be updated.
Btw i recently upgraded another bios with my old asrock motherboard, this from linux and it went ok, iāve been using unetbootin and freedos (which emulates DOS and allowed to flash the Bios).
Iām going to try uefi and see how it goes with this new motherboard.
Thank you
hi,
i think my motherboard (mb) looks like yours, it seems thereās a windows section which speaks of secure boot .
I still need to read the manual of the mb to see if it describes the Bios.
Thank you for this information
