Do you mean those soldered resistor packs? But if those are there, that means termination is on, right? So no need to remove them... But does that also mean that you cannot have an external SCSI device installed at the same time?...
Anyway... I will play around with those jumpers as soon as I can, and will come back later to report my results...
Sorry, I screwed up. I've been working on different systems with 2091, Fastlane, and Rapidfire. The 2091 has them soldered.
