Several kernel aliases are provided which add extra options to the kernel command line, which may need to be used instead of the default gentoo option depending on the hardware:
 * The gentoo-serial option forces a serial console on the first serial port (ttyS0) at 9600bps. This may be required on some older EFI implementations where the kernel can't detect what console to use. Try this option if booting the default gentoo kernel produces no output and if a serial console is used. If the serial console is not connected to the the first serial port then manually select the console by typing gentoo console=ttyS#,9600 where # is the number of the serial port.
 * The gentoo-ilo option forces a serial console on the ttyS3 serial port at 9600bps. This should be used when installing using the HP iLO remote console feature.
 * The gentoo-sgi option forces a serial console on the ttySG0 serial port at 115200bps. This should only be needed on SGI hardware; if the console is properly selected in the default EFI settings, or when using a video console, then this option should not be required.
