Sorry for being late, I tried: I found a laptop equipped with serial port, plugged a nullmodem serial cable on the laptop serial port and on the serial port labeled "1" of the O2 machine. I started minicom on the laptop and selected ttyS0, 9600, 8bit, noparity, 1 stop bit. Then changed in /etc/arcboot.conf, my append line from append="root=/dev/sda1" to append="root=/dev/sda1 console=ttyS0,9600n8 console=tty0" shutdown the O2, unplugged power cable, waited, plugged, swithed on. Then I changed the OSLoadFilename correctly, and typed "boot". During the supposed boot, minicom doesn't display *any* character. It just change the online label from "00:00" to "00:01". Nothing more, Then, as already explained, the red led on the SGI O2 starts blinking. I then tried the same "append" line with my working kernel and it worked as expected: writing to both the serial console and the O2 screen. How may I better debug the problem? Anyone have a working kernel or, maybe, a newer arcboot? Thanks, Giuseppe Il giorno gio, 13-01-2005 alle 11:26 -0800, Ilya A.
