prompt
Automatically display the boot prompt without waiting for the user to press
the Shift, Alt, or Scroll Lock key. Note that setting prompt without also
setting timeout prevents unattended reboots.
restricted
Can be used with password to indicate that a password needs to be entered
only if the user specifies parameters on the command line. Like the per-image
restricted option, but applies to all images.
serial=parameters
Allow the boot loader to accept input from a serial line as well as from the
keyboard. Sending a break on the serial line corresponds to pressing a Shift
key on the console to get the boot loader’s attention. All boot images should
be password-protected if serial access is insecure (e.g., if the line is connected
to a modem). Setting serial automatically raises the value of delay to 20 (i.e.,
two seconds) if it is less than that. The parameter string parameters has the
following syntax:
port[,bps[parity[bits]]]
For example, to initialize COM1 with the default parameters:
serial=0,2400n8
The parameters are:
port
The port number of the serial port. The default is 0, which corresponds
to COM1 (/dev/ttys0). The value can be one of 0 through 3, for the four
possible COM ports.
bps
The baud rate of the serial port. Possible values of bps ...
