How do I update the system bios from Windows?

I have heard that an update will correct the problem I’m having
during shutdown or restart.

Well, unfortunately, the question itself shows a slight

Believe it or not, the BIOS is unrelated to Windows.

The BIOS, or Basic Input Output System, is a part of your computer, not a
part of Windows. It’s software that’s stored within flash memory chip on your
computer’s motherboard. (Flash memory is normally read-only, but can be
reprogrammed with appropriate tools.) Windows, Linux … or no operating system
at all, your BIOS is there as soon as you turn on the machine.

Unfortunately exactly how you update the BIOS varies from one type of
motherboard to another, so I can’t give you specific instructions.
Typically it involves downloading the new BIOS image and an
installation program, often in the same file, copying them to a bootable floppy
disk, booting from that floppy, and running the installation program.

But it might be different for your computer.

So the best advice is simply to check with the manufacturer of your computer
or motherboard. Most likely their support web site will include both the
updated BIOS and the instructions you need on how to install it.

  1. Hello. I have a notebook AST Ascentia P Series. I have new bios data, but i cant burn them, because i dont have a diskette drive for the notebook. How can i burn the bios from the Win98?

  2. That DOESNT answer the question. I have a SOLTEK 85DRV and when i boot into dos all the letters are gibberishand nothing can be read. The drive letter for example is @\ and when i push the I button i get an H but if i push it again i get an I. If i hold H for example i get a sequence, that the system repeats . like this: HIHHIIHIIIHIHI.
    Its saying the words itst supposed to, but in all different letters.

  3. Hello. I have a notebook Compaq prisario 2517AT Series. I have new bios data, but i cant burn them, because i dont have a diskette drive for the notebook. How can i burn the bios from the WinXP?

  4. I’m sorry but… this has got to be the most useless piece of information i have ever stumbled across.

    You have the exact question I would like answering but you simply expand on the question without providing an answer!!

  5. damn, i can fix all your computers, but its easier to fix them than to tell someone how to fix them. too bad AST is dead. i have an Ascentia P series too, and it is a damn fine laptop for its day & age. i lost the cd rom drive somewhere in the last 10 years so i have to use an adapter and put the hard drive in my computer if i want to switch operating systems. i can’t figure out what kind of RAM it uses, so i am stuck with 32mb, but at least im not stuck with 16mb and a 133mhz cpu. i can run windows 98 it is just kinda sluggish. i can’t find the bios updates though because support for AST has vanished

  6. As always, I find your responses solid common sense (or it seems so when you explain your answers) I note the FAQ’s coming up, and the same SENSIBLE, answers being given. Yes, your advice to leave the bios alone except in dire necessity is a sound and complete answer. Out of the ranks of the highly technical experts it is refreshing to find one who is AGAINST unnecessary ‘fiddling’!

  7. Leo, just a little correction on mystyping:
    in the section “You may also be interested in: …” right after the article, it says “Win’s Bios” instead of “Wim’s Bios”.

    Regards and thank you for the article and the link!

    {typo fixed, thanks!}
