First of all, i got this computer: Compaq Presario, sr2020nx. As you can tell, I am having a problem with it. It seems that my ASUS mobo has not been made by asus; i.e. its not on their site. The bios tells me that the mobo is a "6/30/06-C51-MCP51-A8M2N-LA-00" or in compaq words "Naos-GL6"



My bios is:



My video bios says

but its a

All I really know about the mobo is:


Here's what Compaq/HP says

I went to ASUS and typed in my serial #, guess what its invalid...

Here's the problem

I hit F1 at boot, i dont get to play with the good stuff.
I hit F11 at boot, i get an extended version of the bios with 4 more options, but still no good stuff.

I want to unlock the ram(its stuck at 446 Megs, i have 512 Installed,) I wanna unlock the full potential of the processor, and the onboard video.

I helped my friend flash his bios, and afterwards, xp noticed a whole plethora of new devices... I want this to happen for me, as i know i am not getting the most out of my mobo.

sidenote - i downloaded this and have not tried it yet, as I am unsure whether or not it will work on my MOBO, but if anyone can unlock my current bios (if you can find it) i would be very grateful!


Someone help.

Asus won't support the board because it was made for Compaq.
Award/Phoenix do not support or supply upgrades for ANY of their chips. The chips is made per the motherboard maker's specs. Most computer manufacturers make it so you cannot alter or overclock settings. They do offer BIOS upgrades when the need arises
If you attempt to flash a BIOS or video chip and you are not 100 percent cent it is for your EXACT model, you have a good chance of turning your computer into a doorstop

ok so will the bios from this board work in this board?

if so, cool, if not, why not?

There's unlikely to be any "good stuff" to get...

A Compaq isn't a system to look at hotrodding. A board is specified to the cent for the model of system it's to go into, and Compaq tailor their own BIOS to exactly match. That's why the actual manufacturer of the board does not provide any update (or any backup at all).


The download is an update for the Video BIOS (the BIOS in the video chipset), but it's a very small incremental update, to version 5.51.28.50. The site doesn't even list anything it fixes, so there's no way to be sure if it addresses any issue that may affect you. It certainly isn't going to make any significant difference to the capabilities of the onboard video.


64M of RAM is being used by the onboard video, there's nothing you can do about that except fit more RAM, or install a decent video card. With 1GB of RAM, the onboard video could be allocated the maximum 256M it can use - but it would still have the very limited performance of onboard video.

Really the only way to give that system a performance kick is to fit a respectable PCIe x16 video card, and probably bump up the memory, although adding just the video card would release all of the 512M RAM for system use.


Only HP Compaq (or someone who has already tried that exact substitution) would know for sure. But since the only obvious differences between the boards is the first has physical provisions yours lacks (e.g. two extra memory slots and two extra SATA channels), it seems likely any difference in its BIOS would be to accommodate features your board simply does not have.
