Linux: The 0.01 Release | KernelTrap
This is a free minix-like kernel for i386(+) based AT-machines. Full
source is included, and this source has been used to produce a running
kernel on two different machines. Currently there are no kernel
binaries for public viewing, as they have to be recompiled for different
machines. You need to compile it with gcc (I use 1.40, don't know if
1.37.1 will handle all __asm__-directives), after having changed the
relevant configuration file(s).
