I have a Toshiba L630 PSK60A-00E003 running Windows 10. I wish to upgrade the BIOS and some other drivers however the Toshiba site does not give me an option to select Windows 10. Where can I download the best BIOS for this machine running Win 10, Pentium 6100 processor, 8Gb RAM. Also, if I upgrade the processor to an i3-390M will I need to update the BIOS again. Regards Vic
