Sony Vaio VGN-AR61E Phoenix BIOS R2080J8 (12/26/2007) (SLiC 2.0)

[Sml6397]

Hello Boost,

I have replaced the previous example BIOS with an updated image. It now contains the "Penryn CPU Control Sub-Menu" "ICH Workarounds:" (primary menu) "MCH Workarounds:" (primary menu) "frequency ratio:" (CPU multiplier option) and keyboard settings.

So far the "ICH Workarounds:" parent menu looks strange. The frequency ratio option can be changed (even with the NVRAM registers!), but doing so will have no real effect as the setting is locked by the CPU PLL lock.

As before, this is just an example BIOS meant to be emulated in Phoenix BIOS Editor. DO NOT FLASH THIS IMAGE.

Thank you for the links. The PDF contains very useful descriptions of the BIOS settings and how they interact with the system.

EDIT: Post #13 contains a flashable modified BIOS image.

I enjoy reading about changing bits and numbers at the right location with the hex editor, but sadly I dont have the time right now to explore any deeper. Changing hex-values with instructions is one thing, but finding these is another story. So Im really glad there are people on the net that actually know what they are doing.
Im amazed by the amount of sub-sub-sub menus in my phoenix BIOS and can imagine why these options arent there for the "standard-user".

I guess the flash didnt happen, because of the platform data missing. Hence the message "error reading ROM".
Thank god this tool doesnt just flash data files you point at, without asking or testing file integrity.
I would really like to see the result of "Back up system BIOS ROM". (platform data - yes or no)

Good to know our phoenix BIOS ROMs are similar and Im ready for the next mod of yours, to be viewed in the phoenix tool.

Thanks for your support, I really appreciate that !
This is an exciting adventure into the land of BIOS!
