Founded the option and set it on, I see that the output is something like #06.. but it reboots and I can't read so fast! The result is that I can't be more exahustive in the explaination so I answer: How to have a log file to read the outputs?
In the grub/menu.lst you could do like this: module /boot/L4Linux/main -nowait -nokdb -serial_esc -comspeed 115200 -comport 1 Then you could receive the boot message by the ttyS0 (com1) with comspeed 115200. Good luck. Cheng Guanghui
