well, another great day! we booted via tape! :))) the problem was that the eclipse need to load the "MICROCODE" before read anything else; and we had 2 problems: 1) the tape head was so dirty that we can feel the dirt on the head touching with a finger! after cleaning it, the tape reader now perfectly! 2) the microcode original tape is ... in horrible conditions! it release magnetic particles touching it, and the tape reader can't read it :((( BUT we found that a microcode copy can be loaded from the hard disk (a 550 mb disk, very big and huge ! :) so, we can now load the microcode from hard disk and, after that, boot the DG/UX installation tape :D AND WE'RE SO HAPPY, SOOO HAPPY, WE LOVE ALL ! :) the main problem is how to do a backup of the whole disk, to preserve the original AOS/VS installation, before trying an installation of DG/UX. Any hint? :) p.s. some images here: http://dyne.org/~asbesto/eclipse/eflags many tnx to eflags for the help (he's the guy in the photos). It's a sort of JESUS. He touch hardware imposing hands, then the hardware magically works. :) -- [ asbesto : IW9HGS : freaknet medialab : radiocybernet : poetry ] [ http://freaknet.org/asbesto http://papuasia.org/radiocybernet ] [ http://www.emergelab.org :: NON SCRIVERMI USANDO LE ACCENTATE ] [ *I DELETE* EMAIL > 100K, ATTACHMENTS, HTML, M$-WORD DOC, SPAM ]
