So I want to access Advanced Tab in my BIOS but Sony VAIO VPCEB3C5E doesn't show that, I have my BIOS by American Megatrends Inc, R1140Y8 - I figured out I have to mod it, to set access to everything as user, I made a USB MS DOS bootable drive and tried to use AFUDOS to flash my modified BIOS but it said ERROR Bios is write protected. How do I get myself an Advanced Tab in BIOS? How do I flash my modded BIOS? How do I bypass the write protected message? I have researched a lot but I don't really understand anything, so I conclude very willy nilly I don't know what I am doing and need help, lol, also I don't know what SLIC is? Its purpose etc, nor do I understand what UEFI is or its meaning in comparison to BIOS. I just want to change stuff in bios so I can upgrade the RAM to 8GB lol I understand I have to do something with SLIC and set bios access to USER and flash the rom but it just won't work?! Also if you need the rom its 2nd link on google "R1140Y8" Someone teach me something, please!
