Welcome to LQ!
If you will read the Slackware-HOWTO file on the Slackware CD1,
it will answer all of your installation questions. If you are talking
about the part during installation, after Package Series Selection
where you start the Configuration, you should choose Skip and
let it use the kernel it booted to get you that far.
As has been said, your keyboard didn't stop working, the input
of the password is masked, meaning you can't see it. If you
enter it, then it will prompt you to enter it again for confirmation,
then it will continue from there with the prompt for you to exit
and reboot.
If you will look at this thread where I advised someone else
about installing LiLO, I think you'll be able to follow that info
and get yours installed. As Holly said, put LiLO in the MBR,
and use the expert installation so you can choose and see
what you've doing. Here's the link ->
