Is this true? Anyone care to >comment. It's my understanding that the RESET makes it to the Host Adapter board, but doesn't go any farther than that (i.e. it's not passed on to the SCSI controller). I believe that this is not unique to the Atari HD. I think it also applies to the Supra host adapter too. I don't know about ICD. I think BMS is the only one that passes the RESET to the SCSI controller. It appears though that Supra does some special things on RESET. -- David Beckemeyer | "To understand ranch lingo all yuh Beckemeyer Development Tools | have to do is to know in advance what 478 Santa Clara Ave, Oakland, CA 94610 | the other feller means an' then pay UUCP: ...!ihnp4!hoptoad!bdt!david | no attention to what he says"
