[OnLineBios]

Sorry, but now only Hot Swap Bios Flashing can help to recover.

So sad...

What I do anything, the computer is HS ?

You need other motherboard with same type of BIOS chip.
And flash your BIOS chip on such motherboard with Hot Swap Bios Flashing: https://www.youtube.com/watch?v=y8QcVFvTyS4
Use your backup of BIOS.
Or buy flashed BIOS chip - https://www.ebay.com/itm/BIOS-CHIP-ACER-...0138308688

Hi DeathBringer,

I've tried to do Hot Swap Bios Flashing, but I reach not do it.
I've several chip, I've several other computer.

You know the good configuration ?
- computer architecture must be AMD or Intel is ok ?
- BIOS must be Phoenix ?

On another computer when i've changed chip, she not mount in awdflash as on the video...

I should to flash my chip broken, or I need to take another chip ?
How I can recognize that others motherboard is with same type of BIOS chip ?

What types of motherboards you have? It must be have Award BIOS.
1. Boot such this motherboard with its native BIOS chip.
2. Check compatibility this motherboard with awdflash
awdflash check.bin /sy /pn
3. Replace native BIOS chip with your "broken" BIOS chip.
4. Flash your backup:
awdflash R02-B2.bin /f /sn /py
5. Power off
6. Install reflashed "broken" BIOS chip into M5100

Hi DeathBringer,

As I could not flash with other motherboard, I found a chip not too expensive and I bought it.
I was flash the old chip with the original R02-B2.bin, so that I have 2 chips OK for the PC.

Now that I have 2 chips, do you want to try again to change some things on the BIOS or not?

Nice news. I'll make a new mod in few days.

Hi DeathBringer,

Et voilà.
Tell me if the picture is not good enough.

Are there any hidden options in the BIOS that can be unlocked?
They can be useful or not?

Try to flash my test mod.
If it boots with your Athlon II X2 215 then make a screenshot of regedit with expanded key HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0
P.S. Unlocking is offtopic in this section of forum.
