1. Shadow RAM I guess I would need to find a way to tell the northbridge to enable shadow RAM for some range around f0000. I looked through the CS5530A datasheet and see shadow registers but no mention of shadowing RAM. Nor in the GX1 datasheet either. I'm looking for some register in either the GX1 or the CS5530A that would enable this. I am looking for some register that would enable me to remap the C0000-F0000 address range to somewhere in sdram. Is that the right thing to be looking for?
2. Uncompressed payload I'm not sure I understand what this means. Right now, my payload is filo. In the build, I see: dd conv=sync bs=196608 if=/bios/filo-0.4.2/filo.elf of=payload.block cat payload.block > romimage Oh, I guess you must mean this stuff: objcopy -O binary linuxbios_c linuxbios_payload.bin ./nrv2b e linuxbios_payload.bin linuxbios_payload.nrv2b So I guess there is some kind of compression going on there. Which method would be the right thing to do? I'll look at the shadow ram thing first then. Thanks. --- "Ronald G.
