My last attempt to build a smaller kernel without PROCFS, pty, all redundant devices (mostly those with a unit number of 1, since they could easily be achieved by boot -c), and without BOUNCE_BUFFERS (not needed for a 4 MB install, apparently :), yielded a kernel with text data bss dec hex 901120 1155072 60348 2116540 204bbc ^^^^^^ Still more than the magic 2 MB limit. :-( (This is the final BOOTMFS kernel, with 1075 KB MFS, as of the Oct 1 src/release/Makefile.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
