SONY VGN-CR220E Bios version R1121Q0 with SONY SLIC 2.1

[sovem]

Oh, I did several bios updates years ago, but I'm a little "rusted" at the moment...

What should I write when I'm in dos?
Maybe "ph161700 /s/x/force" or something else? Should I rename the .rom file to .wph? I have the bootable usb drive already.
You think that this version (moded bios) is safe for me?

Sorry for the noob questions, but I don't like making mistakes...

Copy 3 files into USB-Bootable, boot to DOS from USB, type flash.bat

Thank you for the replay.

Bios update went trouhg fine - no errors, system boots normaly, without any problems, but I wasn't able to activate AHCI mode or get access to any new ulocked menus.

Any sugestion?

Now I get...
BIOS Version:R1121Q0 - which is correct
Machine Name: Reserved
Serial Number: Reserved
UUID: ffffffff-ffff-ffff-ffff-ffffffffffff

I think everything else is fine, only these 3 parameters are messed up now.

Should I leave it like this or should I re-flash with the original bios?
