Acer Laptop with Phoenix BIOS: BIOS MOD Request

(Revised on 7 December 2010)

Preface & Important Links (Tutorials)


There are a lot of BIOS MOD request forums out there but most of them only specialize in SLIC modification. Our job is to unlock hidden menu in the BIOS. We don't want to use "specialize" word here but we know the "how" to get the job done. Based on the old thread

- Phlash16.exe v1.7.0.18_DiffSize (I have two phlash16.exe, same version but different size) is tested on Acer Aspire 6930G

* Rename your notebook BIOS file (.ROM or .WPH) to BIOS.WPH

* If you have both files (.ROM & .WPH), use .WPH file

* Replace the BIOS.WPH inside this package with yours




Extra info about modified BIOS image for Acer Aspire 9420 at post #4: BIOS_Aspire9420_VT_R5

- This modified BIOS image contain a modified DSDT which is part of ACPI table. You may require to re-install graphic card driver after flashing with this modified BIOS image. The reason is I inject different subvendor-id for graphic card device. It totally cosmetic & will not influence the behavior of graphic card. The modified DSDT is for running Mac OS X. It also absolutely compatible with Windows.



Stay tuned.
