Sony Vaio + Fedora 13 works perfectly – BIOS needs hack

Finally Sony Vaio Z 13.3 Series problem with Fedora 13 Fixed, but need to hack bios for this, but which Graphics card need to change for Static instead of Dynamic. (laptop has hybrid GPU).

To work it properly you need to hack BIOS of your laptop as explained HERE. I used following steps, it is easy and state forward, but there is RISK (so please take care).

Downloads (on Windows machine):

2) Flashit tool (Download from:

3)UNetbootin – Create Bootable disk with freeDos

4) Portable Python – to run script


1) Install Portable Python on USB Drive

2) copy Flashit to USB Drive

2) Copy files as said in TODO

3) Reboot and Boot to ‘Free Dos Live CD’ option

4) run commands
