- cp /.altboot /.boot
Fix the Serial Mouse problem
· cp /usr/bin/ph /usr/bin/ph.bak
· mkdir /tmp
· vi /usr/bin/ph
· Search for the 1st instance of "inputtrap start".
· /inputtrap start
· Replace "inputtrap start" with "devi-hirun kbd fd -d/dev/kbd msoft fd -d /dev/ser2"
· The line should read:
phin -TPK -q && devi-hirun kbd fd -d/dev/kbd msoft fd -d /dev/ser2
· Write the changes to disk and exit (ESC :W :Q)
Reboot the system and let the OS installation complete naturally
· shutdown
