Re: What are the possible Consequences of changing BIOS?

 

First off, if you're not looking to fix something that's specifically

"fixed" and included in a particular bios update, don't do it !

 

It's always wise to have the PC connected to a UPS, in case the mains power

disappears whilst the new bios binary file is in the middle of being

written to your eeprom, that can really muck things up.

 

regards, Richard

That shouldn't happen with any modern motherboard because the BIOS FLASH

chip (hasn't been an EEPROM for yonks) has, or should have, a protected boot

block that will always allow you to update the actual BIOS image.

.... there's lots of yonks old PC's out there :-)

Not as long as it's the right BIOS and done properly, following

instructions. If you're talking about flashing an update, why? I wouldn't

bother with it unless I had a specific reason to need it.

You can render the computer unbootable if you make the slightest error

during a flash upgrade. One could say that this stuffs up Windows (or any

other operating system for that matter).

 

Making a few changes by hand is usually safe.

Updating a Bios by flashing is one thing but changing the BIOS settings is

another. If you're talking about the later then you can usually get back to

the default settings if you screw things up.

Do you flasing the BIOS (updating the version of the BIOS) rather than just

changing asetting there?

> Can it stuff up Windows?

 

 

No it has nothing to do directly with Windows. But, if you use the wrong

version, or if something goes wrong while you're doing it, you can destroy

the entire computer.

 

Do not upgrade your BIOS just because it's X years old and there are

upgrades available. Although a BIOS upgrade normally goes well, it is not

without danger. If something goes wrong while the upgrade is an progress

(for example, a lapse in power) you can be left with no BIOS at all, and an

unbootable computer.

Do a BIOS upgrade if you need to--because you are having a problem that the

new version is known to fix--not just because one is available.

Worst case scenario is a dead motherboard. Occasionally things get broken

and need to be tweaked in the BIOS. It shouldn't affect the files on the

disk, unless you are using some kind of RAID setup that uses an onboard

controller, then I wouldn't do anything without backing up the disks first.

 

Many motherboards now have a dual BIOS solution, so if the main BIOS is

corrupt it uses a backup one.

 

Check your board, as many also have a BIOS capable of flashing, that is you

simply put the new BIOS on a disk, boot the PC, enter the BIOS, and there

will be a listing to update the BIOS.

 

In earlier times you needed to use a bootable disk and boot to a basic DOS

environment, then run the BIOS update program. If you loaded some other

program in the config.sys or autoexec.bat files it could interfere with the

update.

 

As others have said, unless you want to fix a problem or add a function, new

CPU codes for example, then there is no point.

 

If you want to go further, read your mobo manual, or download it from the

manufacturers website.

Read the manufacturers instructions on flashing the BIOS. My latest

motherboards have 3 different ways to flash the BIOS. (some offer BIOS

upgrades through Windows. Could be perfectly fine, but I wouldn't use that

method).

 

If you use a floppy disk, make sure you run chkdsk over the floppy before

and after you copy the files onto it. Do it in the drive that you will use

to update the BIOS. Fortunately I've never had a problem flashing a BIOS,

but I have had quite a bit of trouble over the years with corrupted files on

floppy disks.

 

Do a search on your motherboard and the BIOS revision you intend to use. If

there is a known problem, then hopefully it will be documented - You will

always find a handful of pratts who think the BIOS has busted their PC with

no good reason, usually they are trying to overclock to warp factor five, or

use some memory timings that are way out of spec in the first place.

 

Provided you take a bit of care, there should be no problem. Many of us have

done it dozens if not hundreds of times with no ill effects.

Re: What are the possible Consequences of changing BIOS?

 

What I'm hoping to do is turn off the high pitched beep that the laptop makes

when you press the HP quickplay buttons (pause, play, volume, etc.). I don't

have the instructions to do this.

 

QUESTION:

If your BIOS is messed up, can you still insert the windows xp cd and

reinstall or reformat the hard drive to fix the stuffed up BIOS, i.e. is

messing up the BIOS the end?

The BIOS is not related to Windows XP. It's a hardware issue with the

computer.

Try asking HP for the instructions?
