Installing 6.1 on an IOpener

As an intro to embedded systems, I’d like to install a subset of
qnx 6.1 on an IOpener. One can reflash the soldered in 16megbyte SanDisk
by booting from a laptop style IDE drive.

One piece of the puzzle is to construct a buildfile to make the
filesytem image.

A short list of the hardware is

Processor
WinChip C6 (180 and 200MHz models) C6 info C2 info
Chipset
Via (south bridge)
Memory
32MB 144pin SODIMM DRAM (100MHz running at 66MHz?) data sheet
On-Board Storage
16MB SanDisk SMC
Graphics
Cyberblade i7 UMA
Display
10" LCD (more info?)
Sound
Yamaha YMF715 (LM4835 amp)
Modem
56k internal daughtercard

Notes – no pcmcia, but has USB.

I’d like to build a pretty minimal system to test this out.

Any ideas on the buildfile?

Thanks, Clarence Wilkerson
