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.
Server Management Interface
The BIOS determines if console redirection is enabled, reads the current baud rate from the EMP,
and passes this value to the appropriate management controller via the IPMB.
Sample Setup for Console Redirection
The following is an example of how to configure the console/host and server for console
redirection. In the example below, the console is running Windows* XP with SP3. The console
and server are directly connected through the serial ports of both systems, using a null modem
cable:
Server Configuration
1. Power on the server and when prompted, press the <F2> key to enter BIOS Setup.
2. The BIOS Setup menu displays the Main menu. Use the arrow keys move to the System
Management menu.
3. At System Management menu, arrow to the Console Redirection submenu and press
<Enter>.
4. Arrow to the Serial Console Redirection and press <Enter>.
5. Use the arrow key to select Enabled and press <Enter>.
6. The Serial Port menu should display COM2 as the selected. If it does not, choose Serial Port
and use the arrow keys to change the selection.
7. Set the Baud Rate to 115.2K.
8. Set the Flow Control to CTS/RTS.
9. Set the Terminal Type to VT-UTF8.
10. Press <F10> to save the configuration changes and exit BIOS Setup.
