Sony VAIO VPC113FX BIOS image for the Core i7 version with GeForce 310M graphics, 4 MB in size, with R0280Y6 likely being the BIOS version and the name marking it as ok. The CPU and GPU details matter because firmware for integrated-graphics variants may not suit this configuration. A 4 MB file fits a 32 Mbit SPI chip and is written with a programmer for recovery. Check the board configuration matches, and keep a backup of the original chip before flashing.
