Limitations
Console redirection is a real-mode BIOS extension and has been modified to transition into EFI
space. The transition is actually a parameter-passing exercise whereby the serial redirection
scheme native to the EFI takes over using the settings established in BIOS Setup.
Video is redirected by scanning for, and sending changes to, text video memory across the
redirection channel. Therefore, console redirection cannot redirect video in graphics mode.
Keyboard redirection operates through the BIOS INT 16h handler. Software that bypasses this
handler does not receive redirected keystrokes. After entering EFI, the redirection scheme
changes somewhat, but the effect is the same.
