Some notes about this version:
You can use the audio buttons in the upper left of the keyboard to control the volume.
The leftmost gray button is now escape. The other ones are function keys.
The power button toggles the backlight on and off. Alt-Power button resets the machine.
The games are included for demonstration purposes. The idea is that you can download your own games from the internet and use them on the ia-1. The emulators in this version are darcnes, ucon64, and virtual gameboy.
You can edit the icewm menu in /tmp/config/menu
You can replace the background in /tmp/config/bg.xpm or use icewmbg
You can replace the startup sound in /tmp/config/start.mp3
You can change what some of the keys do by editing /tmp/config/keys
Use xkill to stop programs that are not responding by running xkill then clicking on the program you want to close.
There are programs to toggle the leds using the source code neptune posted. Maillight, powerlight, netlight, and backlight.
There is no need to open a root console because X now runs as root. I'm sure some unix purists may object, but given the nature of the device, I think running as user is unnecessary.
You can use Sylpheed for email and news. Your settings and mail should be saved when you freeze the configuration. Keep an eye on the size though. It wouldn't be difficult to use more space than can be saved in /config.
Also, remember to freeze when you've made changes to /tmp/config and opera.
