You can still do things the "now" way, but only be= cause current EFI systems provide either a BIOS compatibility interface (e.= g., emulate the BIOS) or have an actual BIOS that it loads before executing= a system that requires it.

You should move to GPT, though, since you then get unlimited= (practically speaking) partitions and support for media larger than 2TB. B= ut, keep your old system around, in case you need to roll back to it. Buggy= EFI implementations are still somewhat common.

fx-8350 with 990 asus board.

When I upgrade I believe you have to make changes to kernel to
recognise UEFI.

Can I still use MBR or do I have to switch to GPT?

Also using grub2.

Are there any other pitfalls or advice the Gentoo thinktank can
suggest?
