Hi. I bought my tm p253 with 2.21 insyde bios version, but it doesn't allow to increase intel hd 4000 video ram. Is there any way to flash an older bios? For now, when any Insyde flash tool is run, it show error - for example, for 2.07 bios it shows "BIOS version compare error!". 
And another question: the version 1.13 seem to display no errors, but I am not sure, whether it is compatible with the laptop.
Could you help me? pliz

    Good Morning KIMSANBEK !

    The Bios downgrade procedure is very risky and violates the guarantee of equipment in most countries where Acer offers support.
