Umm, I wasn't very clear there, was I ? :) Actually I was wondering how Oleg had figured that out. That you'd be able to find the information from the VMS source listings is no real surprise. Even though it implies that formally unsupported hardware is documented in the sources. But hypothetically, you have an Adaptec AHA2944UW controller how would an ordinary VMS user figure that out? The hex id is vendor and model related. But how to figure out what PK driver is required? Or is the PKA driver a kind of catch all driver? -----Oorspronkelijk bericht----- Van: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] Namens Brian Schenkenberger, VAXman- Verzonden: zondag, januari 2013 19:31 Aan: hecnet at Update.UU.SE Onderwerp: Re: [HECnet] My newest toy -SCSISE adapter hvlems at zonnet.nl writes: OK, that I understand.
