10.4.2 Keystroke Mappings
During console redirection, the remote terminal (which may be a dumb terminal or a system with
a modem running a communication program) sends keystrokes to the local server. The local
server passes video back over this same link. The keystroke mappings follow VT-UTF8 format
with the following extensions.
10.4.2.1 Setup Alias Keys
The <Del> and <Ctrl>-F key combinations are synonyms for the <F2> or “Setup” key. They are
implemented, but do not appear in prompted screen messages. These hotkeys are only defined
for console redirection support, and do not work for locally attached keyboards
10.4.2.2 Standalone <Esc> Key for Headless Operation
The Intel
®
Server Board Set SE8500HW4 BIOS is configured to support the Microsoft Headless
Design Guidelines which describe a very specific implementation for the <Esc> key as a single
standalone keystroke:
ƒ <ESC> followed by a two-second pause must be interpreted as a single escape.
ƒ <ESC> followed within two seconds by one or more characters that are not forming a
sequence described in this specification must be interpreted as <ESC> plus the
character or characters, not an escape sequence.
When enabled in the BIOS Setup, and sent from a remote terminal, the key sequence
“<esc>R<esc>r<esc>R” will perform a Remote Console Reset.
10.4.3 Limitations
The BIOS console redirection terminates after an EFI-aware operating system calls EFI boot
service ExitBootServices. The operating system is responsible for continuing the console
redirection after this point.
The BIOS console redirection is a text console and any graphical data, such as a logo, are not
redirected.
10.4.4 Interface to Server Management
If the BIOS determines that console redirection is enabled, it will read the current baud rate and
pass this value to the appropriate management controller via the IPMB.
