Lost BIOS Setup screen
 

I recently dumped XP and installed Fedora 14. Since then I have been unable to access the BIOS Setup Screen.

The Laptop is Fuitzu Siemans D Series 8820, The BIOS version is not in the manual.
I wouldn't have thought Fedora could write to the BIOS.
Perhaps it is special key presses causing the problem.

I am impressed with Fedora 14.

hank you.

?

Does the BIOS POST screen show a key stroke for a one-time-boot and does the key stroke open a menu as it should?

Hi,

You should be able to use the BIOS init key. It could be the <del>, F2 or whatever you had before the Fedora install. BIOS does Init and there should be enough time to press the proper key. Most Gnu/Linux don't modify or init BIOS but read then pass to the kernel information. You should still be able to get into the BIOS with the proper key selection.

Most BIOS do display the keys for desired action when the machine is first activated by power on.

Are you using a USB or wireless keyboard? If so, unless your BIOS has support for them, you will not have a keyboard until the linux kernel starts to load during boot. You need a keyboard with a PS/2 connector. Try thy neighbors trash.

The OP mentioned a Laptop.

I know...

It always helps to read the posted information. I thought again and did a quick edit. Let's see if the OP can get into the BIOS or the one-time-boot function. You are right, the manual that I found on-line gives the F2 key as the one that should open the BIOS Setup.

To our Original Poster...

You may not see a POST screen splash, but first see the boot splash screen. If this is the case, try to press the F2 key as soon as you start the laptop.

Lost BIOS Setup screen
 
I am sorry for the delay in answering your posts, I have been ill.
My mouse is hardwired to the Laptop (I do not like Touch pads)
The keys to bring up the BiOS setup screen do not work, the same applies to the BOOT MENU.
I press the keys at switch on. There maybe a series of key
presses which allow the Bios screen to be hidden?

Thanks for your efforts

Strange...

If F2 is the right key to press, the normal expectation is that it should open Setup whether you can see the POST screen or not. I once encountered a Dell machine without a visable POST, just a black screen until the Windows boot splash. I had to guess at when and how long to press the proper key for Setup and try several times before I got into Setup.

I then discovered that if I pressed the Tab key at start-up , the POST screen appeared, but that was a Dell.

Would you be willing to open the case and disconnect the HDD to see if you can then get into Setup? If the system wants an operating system, other than fedora, you could try with another linux live-cd.

It's just a last try and I'm guessing.

Since it seems you have the manual(underlined above).
What does it say about POST, BIOS Setup or even keyboard special key assignments?

I agree, this is strange.

just a silly qustion but doesn't the post/enter bios setup screen thingy happen BEFORE even a boot loader is read from the hard drive, thus the issue should be independent of the os installed?

thorkelljarl 12-22-2010 08:05 PM

Yes indeed...

That's what we all think, frieza. It is usual to be able to get a POST screen and enter the BIOS without a HDD or other drive installed, that is without having any operating system to boot.

onebuck 12-23-2010 06:37 AM

Hi,

Not always. Some BIOS have enable/disable quiet mode for BIOS POST screen.

Your correct with that assumption. But as some BIOS do have a quiet option to enable/disable the POST quiet mode.

On some Laptops there is a silent button that should not be confused with the BIOS POST silent/quiet boot.

@OP I suggest that you look here: http://ts.fujitsu.com/support/index.html

In order to get information/support you will need to answer device specific information that has not been provided to us. Most of it will come off the label on the bottom of the laptop.

sometimes it could be the keyboard :) make sure that the key that you have to press works ;)

Lost Bios Setup screen
 
I have found the fault.I am partially sighted so I use a large Monitor powered by the VGA socket on the Laptop.I was pressing all combinations of keys at switch on when the BIOS screen appeared. The keys I pressed were fN and f4. These keys route the display signal to the external monitor. or the Laptop screen or Both.
The Lapto was sending the signal to the external Monitor but it was not responding. As soon as the keys were pressed the screen appeared on the Laptop.So the fault was due to the duff Monitor.
Thank you all for trying to solve my problem.

Hi,

You are now able to get into the BIOS setup?
