FIXING BIOS...POSIBLE?

[Guest Justin]

Is it possible to fix the BIOS if something goes wrong after you've made a

manual BIOS change?

Not a Windows question - ask a hardware newsgroup.

Give us more info. What did you change?

Undo that change or select the option "Reset to Factory Default" (or

similar). Not a Windows issue anyway.

Not an XP question as others have said, but by "manual" change, I assume you

mean you have entered the BIOS and changed a setting, (or want to)?

 

If you do this and the PC won't boot you can reset the CMOS, (which is where

the BIOS information is kept).

 

Usually by moving a jumper on the motherboard for a minute or so, (see your

manual), or sometimes by switching the power to the motherboard on and off

several times, depending on the manufacturer. This needs to be done from the

PSU, or from the wall if your PSU doesn't have it's own power switch. Again

you need to check the manual or appropriate news group to see if your

motherboard supports this.

 

PS. The BIOS isn't "broken", it usually means your hardware doesn't support

the settings you have used.

 

Off hand about the only dangerous thing you could do in the BIOS is to set

the voltages too high, so make sure you read up on the hazards of BIOS

tweaking. Other changes might make your machine crash etc.

sometimes you can

remove the cmos

battery from the

motherboard for maybe

20 minutes or so.

 

reinstalling usually resets

the settings to their

defaults states.

 

also, those batteries

do not last a lifetime,

so it might be time to

replace it as well.

Yes, of course, you may have to force a Clear CMOS and start all over

with your settings.

Do you mean after changing one of the values, using the BIOS setup program?

Certainly. You can do it again just as you did it the first time.

 

Or do you mean after replacing the entire BIOS program with a newer version?

That depends on what you did wrong.

 

Also note that this is not a Windows question, and really doesn't belong

here. In the future, please ask questions in the appropriate newsgroup.

No, not quite. The CMOS is a volatile memory chip. It looks

after things such as the hard disk type, the power-up settings

and the clock. It loses its information the moment you remove

the motherboard battery.

 

The BIOS chip, on the other hand, is a read-only memory.

It retains its information even when the battery is removed.

Clearing it is not only impossible but quite undesirable: You

would lose the ability to read the screen and use the keyboard.

That's why it's called "Basic Input/Output System". A BIOS

can be upgraded, but only with a special program supplied

by the BIOS manufacturer.

The way the question was worded, I believed the OP was actually

referring to the CMOS, and answered according. Or did you mean to reply

to the OP?

Re: FIXING BIOS...POSIBLE?

 

My reply was to you, not to the OP.

 

The OP said "BIOS" in his Subject line, then two more

times in his post. But perhaps he meant "CMOS" all

along - who knows? If I had this suspicion then I would

prompt him to confirm whether he meant BIOS or CMOS.

Re: FIXING BIOS...POSIBLE?

 

Please reword the question in exactly what the cause was with some more

detail. To my knowledge, I've never made a "manual bios change" as I've

never went that far. Maybe you meant something else.

One can always easily use a simple file to set the bios to defaults.

Not what I been told by a computer tech.

 

It will reset all the cmos settings back to the factory default by

removing the battery.

Yes and no. The BIOS chip (current technology) is "Flash" memory which means

that you can rewrite the bios software using a flash utility program (from

the manufacturer). It's ROM in the sense that the code cannot be changed

without flash software. Recommended only in extreme cases.

Your info is incorrect. When one upgrades a computer's BIOS, THAT

upgrade becomes the factory default.

Yes & NO

 

If he just screwed up a setting in the CMOS, that removing the

battery would fix the problem.

 

However, if he used the wrong flash or the correct flash and it didn't

work. The other options would to reflash with the back up he made or

take it a computer shop and have them use a machine to reflash it.

The subject under discussion was a BIOS UPGRADE.

 

WTF has that got to do with changing a setting in the CMOS!?

 

Screwing up an upgrade to the BIOS is a catastrophic event.

Your reading comprehension isn't too good today.

[Guest PowerUser]

Re: FIXING BIOS...POSIBLE?

 

He's probably in a situation where he can't/doesn't have enough time to even

navigate to the BIOS defaults screen before sh*T starts to happen.

Overclockers must be careful. It can be rewarding but it must be done in

the right way to get brag rights. :-)

I have seen bioses that automatically change back certain values if things

don't work. But it's not always that way.

To Uncle Grumpy,

 

The op was not clear. He said he made a manual change on the BIOS.

They only change on the bios he could make is in the CMOS.

 

It is not catastrophic if you flash the wrong bios, as long as you

have the correct bios backup. Some system will detect if you are

using the wrong type of flash. I know this is from experience.

 

 

To Wally,

 

Where you talking to me or Grumpy?

It can be catastrophic if you reboot, and you have a board with only one

bios. Asus has its crashfree protection, if you don't overwrite the boot

block, then you can recover from a bad flash. But if the bios dies

totally, then you have another problem

Standard procedure is to clear the cmos (bios settings) when a bios flash is

incorporated. This is done manually by a few methods, including the

temporary removal of the cmos battery.

 

Manually changing the bios (noted in the original post) itself it not

usually attempted by most individuals. A bios flash is a programmed change

of the bios program. Initiating this procedure is done manually to some

extent, but, is not a manual change of the bios. But, the OP could be

wording it as that's his/her understanding of the situation.

 

Until the OP decides to clear up the question, the matter is unresolved in

the thread.
