I seen that there is a slic modded bios to Acer 4810tgz and they have same version number as 4810t, i have also seen a slic modded bios for Acer 4810t on this site, but i cant find it now, but as i remembered it was modded June last year, and since then there are released 6 more bios from Acer, and i have requested some to mod it , but i cant seem to find that specific topic anymore, i only find a topic from november last year when i search Acer Aspire 4810t and its that modded bios fro 4810tgz ... but i wont try to flash with it if there is much diffrnece in bios between these models ..
