I've been wondering how people solve the problem of having a driver support features from newer UEFI specifications but continue to work on older systems. Coming from a Windows background, is there some mechanism similar to LoadLibrary() and GetProcAddress() to detect and conditionally load libraries at runtime? Or is the solution simply to have multiple driver builds - for UEFI 2.1, 2.3, 2.4 etc.? If so, which build do you use for the optrom - or is there a solution using some sort of custom loader binary that runs the best driver that's in rom? -- Bruce ------------------------------------------------------------------------------ Slashdot TV.
