Ok friend,
download and unpack this tool, run It as Administrator and upload here the result file You'll get :

You will get a Bios Backup and I will check Eeprom Status !
Try this Mod Bios, It is based on a Sovem Generalized A12 Slic 2.1 version and added Menu Tabs Unlock !
Download and unpack, follow instructions to prepare an USB Dos Bootable Formatted Stick, then copy all files from modified folder into It and Boot from USB, so run Flash.bat :

The link contains two files. The first one is the modded bios, while the second is a backup of the original bios. The instructions are in the archive.

Happy flashing!
