Hello guys, I am relatively new to bios programming, but I try to get deeper, I hope you could help me. I have a piece of art 500$ programmer that I do my job most of the times, right now I am stuck in a laptop with dual bios chip I guess. Model is Toshiba Satellite C50-A-19T, it has 2 bios chips, 25Q16BVSIG and 25Q32BVSIG. I have downloaded the latest insyde bios from Toshiba site in .fd format, renamed the .fd file to .bin file, and reprogrammed succesfully the 25Q16BVSIG chip. The laptop had some common bios failure function with blank screen and some leds, but now it turns on by itself on ac adapter insertion blinking all the leds. Any help would be helpful, I ve never occupied with a laptop with dual bios chips.

motherboard number should write maybe i have -
Re: Toshiba C50 Dual Bios programming
you cannot only write that .fd file from toshiba direct to that chip, you must split that fd file first...
post your .fd file that you get from toshiba, i will split for you,
and more better if you post your old backup bios (4mb and 2mb) too.Comment

Re: Toshiba C50 Dual Bios programming
Here are the file"s you need all new updates even ME REgion. You will find the 4MB file and the 2MB file just make sure you load the correct firmware in each chip. So you know the next time always original file is needed so when asking for a bios file always upload original this is how you know where to cut out the correct size file's out of the update...I could do it without original because i'm doing this so long.
enjoy

Re: Toshiba C50 Dual Bios programming
The laptop is up and functional, special thanks to techman1025, but all these seem really weird to me. Could anyone explain to me how should I see the original separated bios files, to send them to you? Should I export them from each original bios chip? I haven't found any functions of exporting data files from bios chips in my programmer's GUI application.Seing is BelievingComment

Re: Toshiba C50 Dual Bios programming
Hi
All you need to do is pull the chip read it and back it up save it as original file model name and upload it.

Re: Toshiba C50 problem dual bios
You have already posted your request at post #10, the bios and info is there. All you had to do was post the word bump,you did not have to make a new thread.
Anyway,the serial number should be on a sticker on the bottom case,we have the short toshiba part number though "PSCGNE" so someone should be able to help .

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
