[REQUEST] Dell Inspiron (15) 3521/5521 BIOS Unlock

[rglassmyer]

If anyone is still working here, I'd like some help with a bricked Dell 3521 giving one beep at start up. I have dumps from both chips, however, there were two dumps from the 4mb chip that matched and read without error, and two OTHERS that match and read without errors, but there is a discrepancy between the pairs of files, so I'm not sure which is correct. I used a few different software tools to read, so that's why there are a few different dumps for that chip. I was hoping to use the recovery method to overwrite, but I can disassemble the laptop again and write directly to the chip(s) if needed. The bios is currently A08. Please specify which dump files are needed, and thanks so much in advance.

Hello! I would like to request unlock the Advanced Menu in bios InsydeH2O  A16
Model: Dell Inspiron 15R 5521-5461 i73537U 6GB AMD 8730M (though BIOS states 3521 model!)
BIOS Type: Insyde H20
BIOS Version: A16

My problem is dedicated GPU (laptop hangs on driver install , safemode disable device - works ok though fan keeps loud). Can dedicated GPU be disabled through menu?

Trying to fix a bricked Dell 3521... Does anyone have the .hdr and .rom files? I'm not sure how to extract them from the bios. Thanks

So I have a Dell Inspiron 3521 with the A12 version of the InsydeH20 Bios, I downsloaded this file and despite being named "generalized" there's a read me file in which it says the mod is only for "this pc", I assume it was modified accordingly to the info detailed in the bios dump of that user, can anyone modify it for me or tell me what do I need to do in order to make it work with my pc?

UPDATE
Hi. I tried to use eGPU on my laptop for second desktop monitor purposes but to no avail. It doesn't get detected on Device Manager. I guess unlocking the BIOS might help.

I have dumped my A12 BIOS using NEW_BACKUP_FPTs program

I don't want my eGPU investment to be such a waste & I'm willing to donate some money to those who helped me getting my eGPU recognised.

This is my first time modding my BIOS so detailed instructions is needed. Thank you.

Hello I have a dell inspiron 3521 Laptop not dell inspiron 15 3521 but dell inspiron 3521
I would like a bios advanced menu unlock because my Dgpu amd radeon hd 7670M probably has something to do with the bios
It would be really appreciated if someone modded my bios
Im not new in bios but im a bit new in bios modifying i already made my own modded bios but the dump file is bigger than the chip itself
thats why im asking for someone to help me modify it
