[ale] hmm, some ?'s

I was wondering what these files do. I find them in my /boot directory:
boot.b
boot.0302
System.map
map
chain.b
os2_d.b

also I recompile my kernel like this.
make mrproper
"Here I run xconfig and configure the kernel"
make dep
make zImage
make modules
make modules_install
cp arch/i386/boot zImage /boot/vmlinuz-"kernelversion"
"then I edit my lilo.conf"
lilo
reboot

I've been using this procedure for a while and it has always worked, but
since I'm not an expert I was wondering If i'm missing something. Of
course this is just curiosity.
