Powerbook 540c, SCSI CD-R Drives

I got the original Diablo but can't make it work on my 540c. It seems that the game does not recognize my external SCSI connected CD-R drive. Any help for this?

I thought Diablo was powermac only, and the 540c aint a powermac unless you have upgraded it!

It has a powerpc chip in it. The game works all the way up to the point where it looks for the files on the CD to play it. Then it gets confused.

Does it have any problems recognizing other CD's.

Another thought, are you useing the orig Diablo cd or a copy? There seems to be some invisible files on the orign cd, I found that out when trying to run Diablo with a disk image of the cd.
