I don't think you have M-system on our machine. As I said before, the problem you have is that flash_rom can not enable flash write on you chipset so it just can't detect any flash chip.
Well, I ran flash_rom on a few random machines. Older, newer, etc. flash_rom found a standard jedec flash chip on one machine:
probe_jedec: id1 0xbf, id2 0x60 SST49LF004A/B found at physical address: 0xfff80000 Part is SST49LF004A/B
I think it is the one.
But on all others, only mine did the probe_md2802 do anything that was not just 0xff or 0x11. So I was just going on the assumption (perhaps bad assumption) that it was finding *something*. In any case, there is lots of work to do to increase what flash_rom can detect.
Perhaps there are other tools that should be tried. I start to wonder that I shouldn't be using some other kernel device drivers instead (mtd,jffs)? The PC_CHIPS_M810LR port guide does this so perhaps this is the recommended route going foward?
I don't think other software will help for your case. Nobody know how to enable flash write on your particular SiS chipset. Other software will fail as well.
Thanks for your feedback though, Jeff
So this is just junk output? It would be nice if the wiki had "good" output to compare things with.
I don't use DoC for a long time I have no idea what it is talking now.
