Eh ... It could be, but the problem is that I don't have StrongARM SA-110. I
have a ARM710 in my computer :).

I have already a ARM710 in my little RISC PC.

Also about the ARM 710 ?

Thanks for your info, and maybe I should have included the info that I have a
ARM 710 in my computer. But I didn't thought about it, that it could be
connected to the processor. But thanks anyway ...

Somebody else knows about the problem ... has a solution ?
