Your need a NULL modem serial cable available
from any computer store.

Install uucp - I use on the HOST :

uucp-1.06.1-33.7.2.

Also , LILO is broken on some machines and ignores
serial input so make sure you use at least

lilo-21.6-71

On the TARGET

1. Connect the serial ports together ( COM1->COM1 ) with
the serial cable .

2. Modify LILO to use serial line on the TARGET
add to lilo.conf:
append="console=ttyS0,9600n8 console=tty0 "
serial=0,9600N8

Run lilo

3. Add to /etc/inittab on the HOST

S0:s12345:respawn:/sbin/agetty 9600 ttyS0

4. To see ALL THE CONSOLE MESSAGES during boot on the TARGET

mv /dev/console /dev/console.org
ln /dev/ttyS0 /dev/console

5. Start uucp on the HOST:

cu -l /dev/ttyS0 -s 9600

6. Boot your target
