I solved it in another way: made universal OS 9.1 Jaz on another Mac, booted the 6100 from that, copied system to the internal HD. So I had a universal OS 9.1 (with extensions etc. with all kinds of Macs) but it was very slow.
I then found another CD-ROM drive (also non-Apple). This one would be seen by the 6100 (on the SCSI bus) but it would not mount the OS 9.1 install CD. I left the CD in the drive and rebooted the 6100 pretty much thinking of nothing. After that the install CD showed up on the desktop!
I could now install a specific OS 9.1 on another partition of the 6100's HD.
Very complicated. Is this voodoo? I read and remember that the OS 9.1 CD was very tough to handle because of all the restrictions Apple put in place.
The 6100 is still pretty slow with 9.1 (has no cache card). :beige:
