I have a TS11 tape drive installed on my MicroVAX II. Controller = Emulex TC02/FS Tape Drive = Cipher M890 Cachetape(TM) Standard csr = 0172520 Standard intr vector = 224 I desparately need to boot from this device, but of course the MicroVAX boot ROM never heard of a TS11 tape drive. You're supposed to have TK50s. Anybody know some magic incantations I can type at the console to boot from a TS11 tape drive? Something like: >>> HALT >>> GOTO JAIL >>> DONOT COLLECT $200 :-) Many thanks in advance.

Something like: As far as I know, the only bootable tapes are those in the MU family, which are the TK50/70 and the TU81. Of course, some might say that DECtape II's (TU58's) are really tapes, but DEC systems think they're (pitiful) disks.

Of course, some might say that DECtape II's >(TU58's) are really tapes, but DEC systems think they're (pitiful) disks. There is a console ODT routine in the back of the 4.3 system manglers guide for TS drives, but it's only for 750/780/86XX machines. I haven't the foggiest what would need to be done on a uVax... Enjoy.

I guess my VMS bias is showing 8-), but on VMS the only useful bootable items are BACKUP and (possibly) BAD, and there isn't any support to boot these from non-MU devices. The basic problem is that VAXen have too many possibilities for data paths to the tape controller. On the PDP-11, you had a controller which was accessed the same way on all models. With VAXen, you have the Unibus adapter (well, not on a MicroVAX, but...) and it comes in various flavors. The code given in the quoted note works fine for the machines which use the DW750/780 adapter, but (for example) on a 6000 with a BI to Unibus delay line 8-{, the programming is rather complex.
