Hi Mugo,
There never was a disk with drivers for CD rom supplied with the Toaster software unless you are using the Toaster with the Flyer addon it cant be done without a CD rom drive already installed. The 4.1 install has a singal floppy disk that has some updates to the CD rom and you do need that disk to do the install but is has nothing to do with the drivers for CDrom.
The only way to get around this is to get the 3.1 software virsion (40 floppy disks). I have them but shipping would be a fair bit to you from Canada.
