You have to make two root disks in Slackware. The Speakup installation instructions are out of date. The files you need are speakup.s, install.1, and install.2. You boot speakup.s, and then, assuming you've given it the right parameters, you will eventually get prompted to switch disks. Put in install.1, and then it will load from that for awhile. It will then tell you to put in install.2. After that, the install will start, and you will eventually have to supply either the Slackware CDs, or a directory containing all the packages. If you are just wanting to see if you can boot, you could also make a floppy out of the rescue.gz file, and supply that after booting the speakup.s disk. That will let you see if you can at least get to a shell prompt, as the rescue disk contains a very minimal Linux system. As for the correct syntax on the boot disk, it is "ramdisk speakup_synth=xxx." If you were booting from CD, it would instead be "speakup.s speakup_synth=xxx."
