BIOS Modding Recommendations

I think I might need to mod the BIOS on my OEM Dell Inspiron 620. I need to create an AHCI option. I’m wondering what tool or tools you can recommend for that.

What are you trying to fix on a ~10y+ old computer?

I can gain some BIOS modding experience, and try to make some use out of it.

Well you’re not going to find the source code for a proprietary BIOS on an OEM system regardless of age, so grab a copy of the binary and a hex editor and start disassembling it by hand.
