Again and again I want to have my E55 running Linux, but the problem is the serial lines (8-port MDP) is a proprietary interface. So I needed a solution. I had the idea to use the PDC console, months ago. Today hacked a driver (template was serial.c) for a polling PDC device driver. I called it pdc_drv.c, the device is "ttyQ0", with MAJOR 30, MINOR 0 and I use a polling period of 30ms (enough for a serial console i/f). Because I have not further implemented the internel console i/f for my driver, I used the hack with the link of /dev/console --> /dev/ttyQ0 And my machine boots up via NFS ! Perhaps we can make a "driver" out of this "hack" ! In my driver I also use the hack, I have done for the serial.c, that with `^\' I can reboot ( machine_restart() ) the computer to work remote on it !
