First, you need a 9 pin serial crossover cable to hook-up the two computers. Typically you'll find a 9 pin serial cable at Radio Shack and with an optional crossover adapter that plugs into one end of the cable.
I prefer kermit (instead of minicom -- kermit acts more like a common shell)
Set /dev/ttyS? to your specific port number. baud_rate can be set to whatever value you want. (This value is limited by serial cable length.)
* On the box being used to monitor the target box * ~/.kermrc set modem type none set line /dev/ttyS0 set speed 115200 set flow rts/cts set carrier-watch off
Ensure that baud_base is set to match the remote target box's baud_base (can be any other supported baud_rate ie 9600): roger@remote # setserial -a /dev/ttyS0
baud_base <> match the remote target box's baud_rate? roger@remote # setserial ttyS0 baud_base 115200
* On the target box *
To test that it does work with your working kernel do something like the following:
/etc/lilo.conf image = /boot/blah label = blah root = /dev/hda1 append = "console=ttyS1,115200" This will spit-out the dmesg on boot to the remote box. This is what you basically want to occur with Linuxbios. This config option is found within the config file when building the actual linuxbios image file for burning to a mtd device (ie flash, DOC, etc)
Or, add to /etc/inittab: S1:12345:respawn:/sbin/agetty ttyS1 -L 115200 vt102 Restart inetd and this inittab addition will only display the later part of the boot process and will give you a login shell via kermit/minicom.
Ok. After making sure that your port numbers and baudrates are correct, fire up kermit on the remote box. Reboot or restart initd depending on which test method you decide to choose.

I finally succeeded in burning linuxbois on rom, however, how can i see if i succeed or not?
On the HOWTO I should connect linuxbios computer with serial port.....
where should I connect it?
can anybody explain about it?
thanks for any helps
