See the Dell Axim X3 wiki page for
information on porting Linux to the Dell Axim X3.
You may also find extra information on the
Dell Axim X5 wiki page.
The Dell Axim X5 uses MediaQ 1132 as LCD and TFT panel controller it is also
used as extended GPIO(for example card ready signal from PCMCIA is connected to
it) Than it uses AC'97 codec for sound and touchscreen. For more info see

11/13/2003 or 13.11.2003:
I have started porting kernel 2.6 to Axim and will not return to kernel 2.4
since that would just make things more complicated ... you have to wait, since
there is no bootable kernel available right now ....
Things that work
- involve: Touchscreen, sound, LCD, buttons, serial port, charging
Things left to do (in no particular order)
BootBlaster
- Get BootBlaster running on Axim.
- Detect Axim machine type
- Read all of flash for backup
