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.

Lol, got a email for reply after so many years lol Big Grin  I still have bios A12 bios if you want it.

http://www.mediafire.com/file/cg7c9fjab3...d.rar/file

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.

Specs
* Windows 10 Pro 20H2
* 12GB DDR3 RAM (4GB Hynix + 8GB Kingston)
* 128GB SSD w/ 500GB HDD for data
* Intel Core i5 3rd Gen 3337U
* Intel HD Graphics 4000 w/ AMD Radeon HD 8730M as discrete GPU
* Nvidia/Sapphire GeForce 8800GT eGPU (Windows didn't detect it)
* Realtek NIC & HD Audio
* A12 Dell BIOS (Downgraded from A16)
https://www.dell.com/support/home/en-my/...erId=60VPH

I have dumped my A12 BIOS using NEW_BACKUP_FPTs program
https://drive.google.com/file/d/1Kwjl5Vm...sp=sharing

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.
