How to know if my BIOS supports UEFI?
I have a Toshiba Qosmio X505-Q888 and I was wondering if there was a way to have UEFI installed on it?
I agree with what b01 says in that if the hardware doesn't support (U)EFI then you aren't going to find a "Real" EFI that you can make work with it, as the computer needs the hardware to be able to support the EFI firmware (which are very different from a BIOS firmware), as well as any new thing(s) the EFI system does differently than a BIOS.
Depending on what you want to do though, you may be able to get away with a "fake" EFI implementation, and there's (at least) a couple out there due to people making x86 Hackintosh computers.
No, UEFI is a replacement for BIOS, not something to be install like a video card. The board in that laptop has to already use UEFI in place of a BIOS chip.
One way to know is if you go into the motherboard settings, if you see more than 16/256 colors, then you can assume it has a UEFI firmware (just kidding). Even better, I think my board at work states UEFI when I go into the firmware settings.
