OLPC Sound modem

The Easy Way

1. Get DebXO running on a XO with the Terminal Activity
2. Update it as per the DebXO wiki

3. # apt-get install soundmodem ax25-apps ax25-tools

4. # mkdir /etc/ax25/

5. Fake /dev/dsp

   # modprobe snd-pcm-oss

6. # soundmodemconfig

7. configure the settings to your requirements then quit soundmodemconfig
8. insert earplugs :P

9. # soundmodem /etc/ax25/soundmodem.conf

The Right Way

1. Upgrade to the latest official build

2. # yum install soundmodem libax25 libax25-devel ax25-apps ax25-tools

3. # wget haxwithaxe.net/files/kernel-2.6.31.6-2.rpm

   # wget haxwithaxe.net/files/initrd-2.6.31.6

   # mv initrd-2.6.31.6 /boot/

   # rpm -i kernel-2.6.31.6-2.rpm

   At this point you can skip to insmoding the modules we just installed with the kernel as i have yet to figure out how to get the new kernel to be used on boot.

4. # cd /boot/

   # rm vmlinuz

   # ln -s vmlinuz-2.6.31.6 vmlinuz

   # ln -s System.map-2.6.31.6 System.map

   # rm initrd.img

   # ln -s initrd-2.6.31.6 initrd.img

5. reboot

6. # insmod /lib/modules/2.6.31.6/kernel/net/ax25/ax25.ko

   # insmod /lib/modules/2.6.31.6/kernel/drivers/net/hamradio/<protocol>.ko

   # modprobe snd-pcm-oss

7. # mkdir /etc/ax25/

   # soundmodemconfig

8. insert earplugs

9. # soundmodem /etc/ax25/soundmodem.conf
