This is the normal behaviour: LILO has been tweaked to send the output
to the serial port as well as to the video console. But as this early
stage, there is nothing that instructs LILO on how to handle serial input
The same is valid for the kernel load: the "append" will only kick in
after the kernel is loaded.
To fix it, you need to either be lucky or spend money on
additional/substitute hardware.
At least one manufacturer has a serial card that will hijack
video/keyboard I/O, but at $250 the card at www.realweasel.com is not cheap.
Compaq, Dell and AMI (www.ami.com) have similar products: the first two
are very sophisticated include a full PC on the card including independent
video, and 10Base-T and are for the moment OS dependent (Compaq's new
product is supposedly Linux friendly). The last company is liquidating
its console products and you will find them on eBary at $100. They are
NT-dependent if I understand well.
Alternately, you need to have or buy one of the now_starting_to_become
numerous motherboards with a BIOS that supports redirection of the console
to the serial port.
e.g. the server BIOS by Phoenix now supports it
http://www.phoenix.com/platform/serverbios.html
http://www.phoenix.com/platform/preboot-manager.html
and Intel is using it in its server motherboards, such as STL2, SBT2,
LB440GX+ and others that use the Phoenix BIOS.
Tyan also has the series S25xx that often uses that same BIOS.
Notably, most HP PC servers have had this feature since the Pentium Pro
days.
