["Adam Sleight" <adams linearcorp com>]

rpm -Uvh kernel-source-2.2.16-3.i386.rpm kernel-headers-2.2.16-3.i386.rpm

rpm -Uvh kernel-2.2.16-3.i386.rpm kernel-ibcs-2.2.16-3.i386.rpm kernel-pcmcia-cs-2.2.16-3.i386.rpm
--force

cd /boot/

/sbin/mkinitrd initrd-2.2.16-3.img 2.2.16-3

vi /etc/lilo.conf
**make sure to change the following to lines in lilo.conf to reflect as such**
image=/boot/vmlinuz-2.2.16-3
initrd=/boot/initrd-2.2.16-3.img

/sbin/lilo -v

that's how I upgraded and I know that I only need kernel-source if I plan on compiling my own and
pcmcia if using a laptop but what the heck is ibcs? Is it needed?  I want to try out Gordon's kernel
2.2.16 rpm soon too.
