The images of boot floppy on the Trans-Ameritech CDROM are only for 5.25 
inch drives. Sorry.
If you use a SCSI or Mitsumi CDROM, you can use the Slackware distribution.
Most people say it is better than SLS.
If you have a Sound Blaster or Sony CDU31A  CDROM, you need my custom kernel.
There are two solutions: to get the correct 3.5 image from here, or
for you to copy the slackware directory to your dos disk temporarily , make a
boot floppy from the image there and install Slackware (please read the doc i
file in slackware directory).
Then you can either recompile the kernel or copy the right one from
/kernels/
