Resounding silence...
Sorry, your post probally just got lost in all the stuff surrounding the GX2 and OLPC.
Thanks for the feedback - I felt all alone ;-)
Until you get a post card my advice would be to edit the start up assembly and add a series of 5 outs to port 80 in a row and then hang in a spin loop. Then you can look at the ISA IO lines with a scope and see if you are getting the 5 outs.
I have a scope at hand, but I just found a place where I can borrow a PC104-development kit with a POST card :-D So I think I will fetch that kit and get going (I don't wan't to do too much hot-flash-switching if I can avoid it).
To be continued ;-)
