Hello everyone .

I am trying to install Mac os x on my Sony vaio VGN - FW21M , and one of the peculiarities is that I have AHCI enabled in order to install it.

I meet a locked bios which can not touch anything.

My requirement is only that , ( enable AHCI ) but I would like , once I ask for help , if you could locate an entirely unlocked my bios to see all available options and other things .

This is the link for the latest update I have done and been just to display the VT Intel because the processor does.

Me if you need any more information please do not hesitate to ask.

That yes, please tell me the steps to get the data that You ask me , since I have little idea. Thanks for your help! Big Grin

King regards!

You an try this guide :

I did it and followed the instructions and flashed my modded bios with afudos. It flashed but bios didnt change.
I also try to unlock advanced options. By reading this :

I never found the "modified BIOS" from the initial post and Im not aware of what kind of things could be unlocked here.

Anyone has any additional infos about a modded R1100Y0 ?

Here you can download the "Universal BIOS Backup" and the original Setup for the R1100Y0 (EP0000208409.exe).

I tried the universal unpacker on the exe, but it did not unpakc the ROM itself.
Hey Boost! Long time no see! Nice to see you on the forums again Smile

I'll take a look at this over the next few days, probably Sunday or Monday.

In the meantime, could you get a BIOS dump using this tool created by Serg008?

!!!!!PLEASE READ!!!!!! Our Ukrainian friends are undergoing atrocities right now and need support. There are two things you can do for starters:

Also, please feel free to PM me if I have not replied again about your BIOS mod request after 5 days.

Hehe, hey man, thanks for the welcome and the (always appreciated) instant support !

8 years have passed...crazy. And I see you are an admin here now. Smile

Nice collection of tools in the exe but sadly I got a lot of "Error 201: [FPTw.exe] cannot be run on the current platform.
Please contact your vendor."

Maybe I should mention that Windows 11 Home (without TPM and SecureBoot) is running on the device.

Attached is the result rar.

Its a very old device and I wasnt into BIOS modding since many years. But somehow this one grabbed my attention.
Whatever you might reply, Im very curious about it. Smile
