I intend to set up embedded Gentoo on this system, eventually. But first, I want to set up some old x86 hardware on 4G CF cards, along with the Alix and TS boards, just to get all of the hardware up and working. I have these (old PC) systems {AMD-K6, i586, Pentium2, p3 and p4} and these SBC {Alix.2D3-B (Geode) and TS-5500 (AMD elon-SC520)}. I want to set up a simple gentoo install on a 4G CF that will boot all of the machines above, test hardware and then get individual, optimized embedded gentoo running on these platforms some time in the future. I have several of the CF cards, so a single image that boots all of the aforementioned hardware, is the goal. Here is my proposed make.conf (generic x86) settings: CHOST="i586-PC-linux-gnu" CFLAGS="-Os -march=i586 -pipe -fomit-frame-pointer" CXXFLAGS="${CFLAGS}" USE="-* -nls ncurses ssl crypt berkdb perl pcre \ python readline zlib bzip2 nptl nptlonly syslog " Maybe add these flags {fpu vme de pse tsc msr cx8 pge} or will that be redundant? Any refinements or suggestions that will work across the broad range of x86 machines are most welcome. Later, once I start building embedded gentoo from a cross compiled environment, I still want to keep the same flag settings across all of these x86 variants, loosing some performance, but being able to use a singular set of binaries on these minimalist (x86) systems. Your comments and observations are most welcome. James
