After the installation i was not able to enter my bios anymore. Its definately not! a hardware problem.
When i start my PC i have two possibilities: F12 for boot menu and F2 Bios Setup
When repetetivily press F2, nothing happens, i will shortly see “Welcome to Grub Loader” and then i am moved to the screen where i can select between “opensuse 13.1” and “Advanced options for opensuse 13.1.”
When pressing F12, i am moved to a screen with two tabs: “Boot Menu” and “Application Menu”. In the “Boot Menu” i am only able to Select “opensuse”. The application menu only shows “Diagnostic screen”.
thats it! there is no possibilty to enter the bios.
I know that Grub loads after the BIOS, and i know that i shouldnt have anything to do with it, but this would be my first guess. Maybe it has something to do with “EFI”?

Grub can inhibit the bios menu if the last thing you did was hibernate the machine. Grub is set to
automatically boot the correct choice to boot, and bios menu is inhibited. I don’t know how exactly
this is done.
But, at least in my machine, cycling the power button does the trick, as this bios inhibition works
for one boot only, not the second attempt - unless the bios itself has a bug and doesn’t remove the
inhibition.
I only know this by observation, I don’t have a link explaining it.
It is not a recent standard, my laptop with 11.4 has it.

Yes, from your description it sounds like you have EFI system. I guess you have better chances on forum, dedicated to your hardware - it is really your BIOS that behaves this way.
What you could do - is to attempt to reboot into setup screen using grub2. On grub2 menu press ‘c’ (single character) to enter command line. Then do
fwsetup
If your system supports it, grub2 will try to reboot into firmware setup menu. Then you may try to fix the problem there.

Check the user manual for your computer for a jumper or other method of
resetting the BIOS to defaults. It may be a lost cause or require a lot of
effort to get to it but I have had at least one instance where that was the
only way to get into a BIOS setup. If this works, keep a careful record of
the BIOS changes you might make just in case the problem returns.

It is not a urban leyend, I can prove it. My laptop does what I described.
When I hibernate, on first boot I can not reach the bios, it does not respond, and the “hit supr key
for bios” message is not displayed.
This is done by Linux.
I don’t write lies. :-/

Which suspend method are you using? I suspect that you are using “platform” which calls ACPI. Your BIOS may be so intelligent that it skips usual boot sequence in this case. Or you are using “suspend” which does not turn system off at all, but rather suspends to RAM after writing hibernation image.
Try using “shutdown” which actually does normal shutdown after creating hibernation image. Do you still miss normal boot sequence?
This is done by Linux.
Please show me code in Linux that disables BIOS setup menu.
I don’t write lies.
That does not mean your interpretation of what happens is correct. There is slight difference between saying “after hibernating my system I cannot enter BIOS setup screen” and “grub/Linux disable BIOS setup screen”, do not you think?
Using your own words - prove it Show me code in grub or Linux that does it.

I just made a video that proves it.
On first boot, on my hibernated machine, there is no bios message: just the Compaq logo, then the
openSUSE logo straight as initial kernel loads and reads the swap. I force a reboot this instant
(ctrl-alt-supr), and on second boot there is the bios message on the bottom left, and next, the grub
menu.
It weights 18 MB. Tell me where to upload it if you want to see it. Or I can email it to you (I know
your email from the mail lists).

You can upload videos for free to Vimeo (and YouTube if you want to wait hours to do simple uploads).
Free access to all non-mobile devices. Have to pay for videos to be formatted for mobile devices.
Uploads are automatically formatted although I personally try to format myself before uploading (It’s just me).
If your video was taken on a smartphone, just search for the Vimeo app in your device’s Store (eg Play Store if Android, Apple store if iOS).

You should have said this before, instead of implying I was lying, telling urban legends :-/

I tried this just now, and you are correct, using “shutdown” does present the bios message.

I did say so, that after hibernating my machine I can not enter BIOS, and that grub doing it was my
interpretation. I have said so in two different threads.
