Samsung RV411, unlock option to change the size of video memory

Hello all,

Try following these instructions instead.

I tried these instructions months ago and also failed. Today opened the notebook to clean it, and decided to write the BIOS with an EEPROM SPI programmer, and when removed the EEPROM to begin the process, think I figured out why I was not getting before, the EEPROM is write-protected on the board, how can see in the image below:


According to the datasheet, pin 3 is WP#, on the board is connected to pin 4 (GND), when WP# is low (connected to GND) means that the EEPROM is write protected.

I think this notebook (RV411) or that particular motherboard model (Jinmao 1.2-L) is impossible to update the BIOS by software. The BIOS you unlocked is working correctly as you can see in the video below:



Thank you for unlocked the menus, especially the "DVMT Pre-Allocated" (0:48) I can now have 128 MB of dedicated video memory which benefits some programs and games, also like to know if there is any way to increase "Total Graphics Memory" for at least 512 MB?
