Intel® Server System S7000FC4UR TPS BIOS Role in Server Management
Revision 1.0
205
The BIOS console redirection feature can support both legacy 80x25 text mode as well as EFI
graphics console support used to display BIOS Setup and graphics based character display.
Redirection of the splash logo image is not supported.
Console redirection ends at legacy operating system boot (Interrupt 19h) or when an EFI-aware
operating system calls EFI Boot Services using the ExitBootServices command. The operating
system is responsible for continuing the redirection from that point.
18.2.1 Keystroke Mappings
During console redirection, the remote terminal sends keystrokes to the local server. The
remote terminal can be a dumb terminal with a direct connection and running a communication
program. The keystroke mappings follow VT-UTF8 format with the following extensions.
18.2.1.1 Standalone <Esc> Key for Headless Operation
The Microsoft Headless Design Guidelines describe a specific implementation for the <Esc>
key as a single standalone keystroke:
<Esc> followed by a two-second pause must be interpreted as a single escape.
<Esc> followed within two seconds by one or more characters that do not form a
sequence described in this specification must be interpreted as <Esc> plus the character
or characters, not as an escape sequence.
The escape sequence in the following table is an input sequence. This means it is sent to the
BIOS from the remote terminal.
