Two BIOS Updates but which is the right one?? using VPCCW1S1E.
1. BIOS Y5 R0190Y5

2. BIOS R0190Y5

They do look the same to me.

The best is to download both and simply compare files.

what to compare except the file size and release date? i dont wanna mess with the bios soft. logically the most recent file, its the right one to install if both the files are meant for the same bios

the file size is the same but the dates not.
