what can I do with DBox2
 
Hi,
I just got a DBox2 (its a decoder to watch pay TV) and flashed Linux on it :)

Now I wonder what could calculate it useful while I watch TV?

$ cat /proc/cpuinfo
processor : 0
cpu : 8xx
clock : 67MHz
bus clock : 67MHz
revision : 0.0 (pvr 0050 0000)
bogomips : 66.76

$ free
total used free shared buffers
Mem: 30892 29480 1412 0 3548
Swap: 0 0 0
Total: 30892 29480 1412

allthough RAM is very low I managed aleready to get Mlucas running on it but I think it would take years to finish just a current double check.
Do you know a factoring program which I can compile for small ppc machine?

BTW I tried to comple Glucas too but Iam not familar with crosscompiling:
On the DBox2 there is no compiler stuff installed (and it would not make sense IMO)
So I have a crosscompiling environment on my PC in
/home/rudi/dbox2/cdk
there is a bin directory with the cross compiler powerpc-tuxbox-linux-gnu-gcc c++ cpp etc.
How can I tell the configure script of Glucas to setup crosscompile with that environment instead of my host-gcc?

(For Mlucas it was enough to do
path_to/powerpc-tuxbox-linux-gnu-gcc --static -static-libgcc -o Mlucas *.c -lm

Hi, Rudi: the RAM would be enough to do some LL testing, but I'm afraid the clock speed is just too low to make this hardware of much use for either factoring or LL testing. I don't mean to tell you what you can or can't do with your box, just that given its capabilities and my limited time, I simply can't afford to spend time on software support for this kind of hardware. If you managed to get Mlucas to build, feel free to fire up some double-checks: I hope you're a very patient person, though (and willing to remind the server every few months that you're still working on an exponent, so it doesn't expire on you.)

You could watch PayTV with it.
