At the GRUB command the "serial" command: # From the GRUB manual: ----------------------------------------- 13.2.12 serial serial ['--unit=unit'] ['--port=port'] ['--speed=speed'] [Command] ['--word=word'] ['--parity=parity'] ['--stop=stop'] ['--device=dev'] Initialize a serial device. unit is a number in the range 0-3 specifying which serial port to use; default is 0, which corresponds to the port often called COM1. port is the I/O port where the UART is to be found; if specified it takes precedence over unit. speed is the transmission speed; default is 9600. word and stop are the number of data bits and stop bits. Data bits must be in the range 5-8 and stop bits must be 1 or 2. Default is 8 data bits and one stop bit. parity is one of 'no', 'odd', 'even' and defaults to 'no'. The option '--device' can only be used in the grub shell and is used to specify the tty device to be used in the host operating system (see Chapter 15 [Invoking the grub shell], page 55). The serial port is not used as a communication channel unless the terminal command is used (see Section 13.2.14 [terminal], page 41). This command is only available if GRUB is compiled with serial support. See also Chapter 7 [Serial terminal], page 23. ----------------------------------------------------------------------- # The GRUB manual is available at: http://www.gnu.org/software/grub/manual # Referenced previously but still a good resource http://www.tldp.org/HOWTO/Remote-Serial-Console-HOWTO/configure-boot-loader-grub.html Have Fun!

Also check your BIOS setting to ensure that it allows booting without a video card.
