I've been trying unsuccessfully to change my ATI Radeon HD mobility 4670 (that I'd previously changed from a HD Mobility 4570) by a AMD Radeon HD 6770M on my laptop a EasyNote LJ65.
I've found on an other custom BIOS site, a modded BIOS :
-Model: Easynote EN LJ65
-Bios Type: INSYDE
-BIOS VERSION: V2.14_A_A
-BIOS SLIC : ACRSYS 2.0
-Bios Download Link : http://global-download.packardbell.com/GDFiles/BIOS/BIOS/BIOS_PackardBell_2.14_A_A.zip?acerid=634290284823722833&Step1=Notebook&Step2=EasyNote&Step3=EN%20LJ65&OS=V10&LC=fr&BC=Packard%20Bell&SC=EMEA_13P
-BIOS SLIC : ACRSYS 2.1
But this one has no effect on my problem : my BIOS don't want to launch with the new card (and so the computer too). I've asked on forums specialized in laptop gaming and a lot of people said to me that the microcode of this graphic card is simply not included in the BIOS so it can't launch it.
I know, I'm not asking for a easy task but is it possible to include in a way or an other the microcode of the 6000M series in the BIOS of my laptop or remove the graphic cards whitelist if it exits so I can install the new card into it ?
Thanks in advance.
PS : I've found on a forum the code of the card if it can help :
Name Radeon HD 6770M
PNP Device ID PCI\VEN_1002&DEV_6740&SUBSYS_3389103C&REV_00\4&31AE8F37&0&0008
Adapter Type ATI display adapter (0x6740), ATI Technologies Inc. compatible
