I am using the official version of BIOS (Inspiron_3493_3593_3793_5493_5593_Vostro_3491_3591_1.13.0), updates from 1.4 to 1.13. The "Video" section has several simple settings and does not have the necessary setting for changing the amount of VRAM. the "Advanced" switch doesn't change anything. As far as I know, all versions of integrated graphics processors have this setting in BIOS. Therefore, please modify and complete the BIOS.
