I have tried the above bin files, first two from imranomi did not work, one was too small, other correct size but programmer would not open. The third one opened and I was able to program it in, however, it still asks for the power-on password.
Yes, I did try all the passwords possible from bios-pw.org and none worked.
I reprogrammed the laptop to its original BIOS bin:

Is the password elsewhere? The laptop shows an AMD BGA chip next to the bios chip.

Which kbc it uses?? If it is programmable kbc, then password may be stored there like kb9012 etc.

According to the schematics, it is indeed a KB9012QF-A3 LQPF128 14X14. How would I reprogram it? I have a TL866A.
I found this youtube video, and he says that I need an RT809F. Looks hard, but if things were easy, any fool would do them.

Its not that hard with Rt809F though svod is easier. You need to get any one of them or some similar programmer. Once you have the programmer in hand, members here will help you out. Dont worry about that part. Go ahead and buy one as this tool is a must for laptop repair these days as all new models have kbc programmed.

The SVOD is a bit pricy for me:

Right now, I only have one computer to fix, so the cost doesn't justify buying it.

You can use a bus pirate, or a cheap ch341a programmer.

Re: dell inspiron M531R-5535 bios dump needed

Thank your for the advice. I will order the ch341a programmer.

If you prefer windows over linux you can use flashrom on windows.You`ll need the kb9012 patch as well, further down the page.

Re: dell inspiron M531R-5535 bios dump needed

I had forgotten about this computer, customer never picked up and now I am finally trying to "fix" it. I have the ch341a programmer but I am not sure about the data input and output pins. According to the first website using a bus pirate, MISO = DO and
MOSI = DI. Problem is that my programmer has MOSI and MIOS. Just to make sure, is MOSI still DI and MIOS=DO?

I am using the windows program from the win-raid forum too.
