Question Fail boot after update bios

[Darker Knight]

I downloaded a custom BIOS on my old computer. It worked normally but I went into the custom BIOS settings and activated some new options added in the custom BIOS and when I did that I tried to turn on the computer but it showed me a black screen with no response when F2 I don't see any sound in general everything doesn't work I tried removing the battery I left it for 30 seconds but it still didn't work. Is there an actual solution for a dead computer due to the BIOS?

My module Laptop : Acer Extensa 5235

Well, why is it a "custom" bios; what's different compared to an official bios; and what settings did you change? I would suggest first trying to boot without making any "custom" changes to see if it boots using the default settings.

Route Port 80h cycles

Changed from LPC To PCI
I changed this option and also the processor does not support virtualization and made it supported by enabling the option in the modified BIOS

There are many options that I modified that were not supported by the computer, but I made them supported through the modified BIOS.

How do I reset the BIOS to default?
I tried removing the CMOS battery for 10 minutes and it didn't work.

Not just scary but most probably dead. Sparks belong to Tesla coil, electronics don't like it, doom and gloom.
