Hi MontrealCL,
If you email me a picture of your original WB 2.1 disks (so I know that you do indeed own them) I will ship you a copy of my WB 2.1 disks. Just mail me 5 blank disks and $4.95 for S/H (includes padded mailer envelope and First Class Mail). I was having the same problem this weekend with one of my Amiga 2000 computers. I found out that I had failed to remove the SCSI terminating resisters from the hard disk when I installed a new CD ROM drive. So my Amiga thought that the hard disk and the CD ROM drive were the same and would not boot half the time. I too was installing WB 2.1. I now have a WB 1.3 Amiga 2000, a WB 2.1 Amiga 2000HD, and a WB 3.9 Amiga 2500. I have the best of all three Workbenches. :-D
