编译内核的问题~求肋

bothersue

命令：make modules

有以下报错：
warning: kernel is too big for standalone boot from floppy
sh -x ./install.sh 2.4.20-13.7custom bzImage /usr/src/linux-2.4.20-13.7/System.map ""
+ '[' -x /root/bin/installkernel ']'
+ '[' -x /sbin/installkernel ']'
+ exec /sbin/installkernel 2.4.20-13.7custom bzImage /usr/src/linux-2.4.20-13.7/System.map ''
/etc/lilo.conf: No such file or directory
make[1]: *** [install] Error 1
make[1]: Leaving directory `/usr/src/linux-2.4.20-13.7/arch/i386/boot'
make: *** [install] Error 2

请问什么原因呢？高手请指点一下。
之前的
make mrprop
make menuconfiger
make dep
make bzImage
make install
都通过了。
