Hi,
I don't know how, but it seems that i have bricked my bios.

I was configuring it, to disable C-States, and maybe i have changed a paremeter (can't figure out wich one), but now when i boot my laptop ( INote N70Z ) there's a boot loop ( the computer starts up with backlight lightning and it shuts off and then try again and again to boot ).

So i will need to flash my BIOS by SPI, if it's possible !?
A bit of help would be apreciable ;)

I have only a *.bin BIOS file that @Lost_N_BIOS kindly unlocked.

EDIT by Fernando: Both posts merged (to save space)

Since your PC isn't booting any longer you'd need a (CH341A) hardware programmer. Tried to remove cmos battery/ reset cmos?

Yes i have already tried to remove the battery but nothing changed!

Is an arduino could be used as programmer, as it has SPI pins?

It can as long as u know the pin connections between the Arduino and the SPI chip
As lfb6 stated, the motherboard needs CMOS battery ON/OFF, AC ON/OFF
Also correct identification of SPI chip voltage

EDIT: Visually identify chip ID, Google is ur friend

@MeatWar

I have already tried to remove the CMOS battery, and the laptop battery and push on the power button while the two batteries where disconected, but nothing happens ...

Here is a picture of the SPI chip, maybe you Can help me to find a datasheet to know the chip voltage? I have been searching a bit, but as m'y wife is seriously hill and u nées tontaje carenof my baby, it's a pain hahaha....

I know how to find a chip on the web, i studied electronics!

But unfortunately i can't find anything about that chip!!!!

Is this the bios region of the same machine in this post?
OverPowered TONGFANG CyberPower Machrevo MACHENIKE - Unlocked BIOS Guide W/ Files (44)

You didn't write a chip ID or post any picture in this thread, so it's mostly empathy we could help with so far?

@lfb6

Sorry i was away for some time!

Yes this is the same machine that the link you posted.

Well for the chip i hope will find the datasheet, but the printing is ugly on the chip so a bit unreadable, i will loo at it with a magnifier!

And i was wondering how i could SPI flash the bios as i only have th *.bin file.

Yes i have already tried to remove the battery but nothing changed!

Hi everybody,

@lfb6

I have finally managed to read the characters on the SPI chip so it'a a 25B127DSIG.
So according to the datasheet it's a 3,3V voltage.

I will find a tutorial about how to run the arduino as an SPI programmer, but i wonder how to convert BIN file of my bios in a flashable format, or if the BIN format is good for SPI flash?

Thanks a lot for your replies.

EDIT: Her is a link to the datasheet of the SPI chip 25B127DSIG Datasheet

EDIT: Ok after reading this tutorial SPI Flash tut the bin file seems to be good, so i will not need any help, i hope so hahahaha

Best regards

I am getting closer froom my solution but i have an issue.

Maybe someone could help me.

It's been about 18 years i haven't used Linux so i am more than rusty about it.

So i need to flash my arduino which is a Mega 2560 with Flashrom but i can't figure out to tell AVRDUDE that it's a Mega2560 and not a m328p as you can read below.

avrdude done. Thank you.

I will search on the web for the solution but maybe a kindly forum user would be faster than me, and if not i wil edit my post for helping future users ;)

EDIT: I'm getting closer and closer ;) Using man avrdude is the answer to help me configuring AVRDUDE.

Sorry i'm really rusty about using Linux hahahaha, but i will get it ^^
