Hello Lorenz and all others
Thanks for the quick reply.
What you suggested is exactly what i've done!
Sorry I didn't explain it enough.
my lilo.conf has the following in the global section:
boot = /dev/hde
prompt
timeout = 50
vga = 0
append = "console=ttyS1,19200"
serial = 1,19200n8
disk hde
bios = 0x80
And I can use the serial connected terminal to send commands while lilo waits
for an input! This is OK. But then the system hangs ( nothing more to see in the
terminal window )
after the message 'loading kernel.......' was coming up.
Has anybody an idea how to debug the startup ( Kernel messages ), for example
writing something to a file.
Perhaps the problem comes because of the serial interface. When starting DOS on
the flash disk there is a mechanism that i get startup messages over the serial
line to a terminal. After DOS is loaded I have a dos shell available on the
terminal connected with COM2. ( COM1 is not available because
there is only TTL on COM1 )
I thought that when Linux is coming up it is using it's own methods to acces the
hardware
such as the serial interface?
How can linux write somwthing to serial interface at startup time, without
loaded any drivers?
I hope on more info
