Hi There,
I've seen a lot of video's of dumping 8FC8 bios. Some of them are a little outdated I guess. Can someone tell me what is the most easy way (what tools to use) to create a dump of my 5520 laptop?

[Vesko356]

You need a bios programmer. Read BIOS guides, methods, resources and tools thread to get the basics.

Thanks! I flashed my bios chip with this .bin but now my laptop doesn't do anything anymore, no boot, no LED, no fan spin (probably my own fault tho).

Would this be the same as the one from the dell website using the service tag?
My laptop locks immediately after power up, I can't even get to the bios menu using F2
