Thank you. I will test it out and get back to you.

Excellent! Everything is unlocked and all the options I'm looking for are now shown on the BIOS screens. Thank you for helping revive this old AMD laptop!

[CivicObligation]

Any chance of getting it up dated with the latest AHCI/RAID Rom and microcode?

Sorry, I've been busy.

I'm not very good at this, but I still want to help. For cpu00100F63 (Turion P540), the latest microcode version (C8) is already installed. I just updated OpROM 1002-4391.

Replace BIOS.fd with this one.

[CivicObligation]

Awesome. Thank you so much for your help

[CivicObligation]

Out of curiosity, how did you perform these modifications? Using H2OEZ seemed simple and straightforward. However, nothing ever changed after I flashed the modified fd. But, it took the changes when I flashed your mods. I'm the type I'd rather learn how to do it myself than have to depend on people to do things for me, you know.

H2OEZE for microcodes and OpROM.
Unlocking Insyde BIOS tabs in IDA using a variety of methods that depends on BIOS version, unsuppressing Insyde BIOS settings with a hex editor and EFI variable dumper. Packing / unpacking it all with the Phoenix Tool.

The mod is done, so you can manually examine the changes. To reproduce, you need to know the basics of assembly: general opcodes, work of memory addresses.

BIOS works great and has provided a whole lot of new options that weren't previously available to be changed. However, I cannot find any way of turning off secure boot so that I can switch the system to UEFI. I'm assuming that it's secure boot preventing it anyways. I'm using Rufus to put Win10_20H2_v2_English_x64.iso onto UEFI USB. Used Parted Magic from UBCD on USB to format hard drive GPT. Do you have any suggestions or insight? I've tried to install Windows with every combination of all these options in BIOS:

SATA Configure as:
AHCI
IDE->AHCI
AMD->AHCI

AHCI supporting as:
Legacy Mode
UEFI Mode (native)

UEFI Boot:
Enabled/Disabled

Quick Boot:
Enabled/Disabled

ACPI Selection:
ACPI3.0/ACPI4.0

USB Legacy Emulation:
Enabled/Disabled

Ihis is just the case if you do not see it - then it does not exist. I have unlocked everything and just checked for NO secure boot.

ISO on USB hard drive? You need .img, your iso does not appear to contain a partition table.
