It depends on what you put in and take out. Most of the kernel is reserved for the various system tables, so your device optimizations may not have a sizable impact on the kernel size. > I am also confused about: > >machine "i386" > >cpu "I386_CPU" > >cpu "I486_CPU" > >cpu "I586_CPU" > > The explanation in LINT mentions that the machine specifies the cpu > one is compiling for. Can I change "i386" to "i486"? No. Leave machine alone. You can delete the CPU lines that don't describe your computer's CPU, though. If you have a 486, you can dump the I386_CPU and I586_CPU lines. That will enable some 486-specific optimizations that may speed things up a tiny bit.
