    G74sx Original BIOS

    Hello guys, this is my first post here.

    I think ive just messed up my notebook by trying to update my bios.

    Do you guys know if there is any way to find the original BIOS (201), so i can burn into my mobo?

    I can RMA it, but im in Brazil, so i dont want to waste that much time (and money) since i really know what im doing.

    If your laptop no longer functions after a failed BIOS attempt (i.e. you are now unable to access the BIOS), it will not be possible to reflash the BIOS. Recovery requires a special tool to rewrite it, and requires an RMA to ASUS.

    Thanx for the quick response "dstrakele"!

    There is mobo specialists in my state that can reburn the bios in the chip with that tool. Thats why i wanted to know if exists any way to find the original 201 BIOS to burn in.

    Any advice?

    I see only 202 and 203 here: http://support.asus.com/Download.asp...74Sx&p=3&s=336 You need to enter your OS version.

    Just curious - Why wouldn't you want to just overwrite the BIOS chip with 203?

    Hm, nice question!

    I think i can ask this to the specialists i told you. They only told me that they need the original bios software, and not the upgrade ones. Anything new ill let you know...

    Thanx again!

    Interesting... I was under the impression that the tool capable of rewriting the BIOS on the chip could rewrite any file version. Never seen or used one, so that was only my assumption.

    Hum... i hope someone can help me now!

    They told me that needs the ".rom" file, 32mbits, instead of the ".202/.203" file, 2mbits, that ASUS provide in their download section.

    I think we getting somewhere. Any advice?

    Any BIOS file can be renamed with the ROM extension.....this is commonly done with the files when used in emergency flashing procedures. Maybe that's all they meant?

    You can get BIOS 201 from your cd driver. Open Root folder. See G74Sx.BIN file. That's BIOS 201. You just can check the BIOS version with WinFLash...(If Possible).

    Thanks, Brody!

    Nice to know, ill tell them this tommorow!

    The 32 or 2mbits, part... makes difference?

    This is not what I want, but if they can not do it anyway, you guys would rely on things like this:

    And In the latter case (past it), there is somewhere I can find a new motherboard G74Sx?
