Windows 7: Bios update procedure

Sara,
You should check with Asus regarding that motherboard. The download link for that board doesn not even list Win 7 as an operating system. Often you can use Vista drivers, but not always.

Sara,
After further investigation, the board is simply too old.

I strongly advise that either from a place like Fry's or NewEgg you get yourself a modern economy board.

Don't even think of fooling around with the BIOS until you know that's the cause.
Since you're going backwards with the CPU, BIOS probably has nothing to do with your problem. Why do you think the 3.0 CPU is bad? Why do you think the 2.8 CPU is good? Can you answer those questions?

Victor,
Often one uses what one has.
Sara never used the word good or the word bad.

I have downloaded bios update from website.

Pl help.
I know of no way to update the BIOS on an Asus board if the machine isn't at least bootable into the BIOS setup.

The manual is available here:

http://dlcdnet.asus.com/pub/ASUS/mb/...22_p5gl-mx.pdf

I recommend the EZFlash method, but your PC isn't running enough to use it.

Is your new CPU on the supported list?

ASUSTeK Computer Inc. -Support- CPU Support P5GL-MX

(If it is, you'll find whether your BIOS version is new enough to support it, assuming that you know what BIOS you have.)

I'm not sure whether the board uses a socketed EEPROM chip for the BIOS. If it did, and you are in the US (or Canada), Asus will sell you a replacement chip, programmed with the latest non-Beta BIOS, for $15 plus shipping. (http://us.estore.asus.com/, down at the moment.) Whether it's worth even that modest sum to resurrect an old 915 based board, you'd have to decide.

Assuming that Pentium 4 2.8 GHz processor is on the support list, and I can't imagine why a board that will run a P4 3.0 would not, then you must follow standard procedure when replacing a CPU:


1) Always reset to BIOS defaults before making the change over (Too late now for you, but for everyone else).
2) after shut down and power disconnect, and CPU replacement, perform a CLRTC procedure.

This creates a fresh checksum and will allow the new processor to be recognized by the board.

CLRTC Procedure:
  • Note all your current BIOS settings (not applicable in your case)
  • Shut down the computer > remove the power cord.
  • Remove the 3v battery.
  • Move the CLRTC jumper from pins 1-2 to 2-3.
  • Touch a metal part of the case and Press and Hold the reset button for approx. 30 seconds to discharge all power from the board.
  • Put the CLRTC jumper back on pins 1-2.
  • Replace the 3v battery > replace the power cord > boot.
  • Immediately go back into BIOS and reset all your preferred settings. If the CLRTC worked you will need to reset the date and time.
Give that a try.
Sorry for not noticing that you could not boot in order to upgrade BIOS. As said, it is probably not necessary to do this if you are downgrading the CPU.


Hope that helps!

Are you sure about the motherboard?

I don't want to expend effort on a wrong board.

Dear Sir,

My original motherboard is of Intel 915, But I am trying this 2.8 cpu on my spare Asus with above mentioned model. As per Asus it supports this cpu. Then why not display is there?

How did you confirm the original CPU was bad? Could it really be that there were problems with the board itself and that's why the "new" CPU isn't working either?
