I could provide some code to map the Geode GX1 cache anywhere you like. It simply uses the tr3, tr4 and tr5 registers to map each cache line to a physical address. I'm currently using it to map the scratch pad RAM to enable and use the video acceleration. Its written in C, but its very easy to rewrite it in assembler. Maybe it achieves LinuxBIOS's requirements, but I'm not sure. Juergen -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
