I use the same setup, 2091 with latest roms and latest controller chip. I boot my A2000 from CF card with the CF in the CF slot, not in the pcmcia adapter. The 2091 with LUNs enabled, will scan through all LUNs on all scsi devices first, and flash the HD light. Sometimes, if I change something, it will go through twice. It takes about 30 seconds to a minute to boot this way, but I don't mind, as it is better than having the pcmcia adapter sticking out all the time, and I can use all of the slots this way. If I use the pcmcia adapter, it boots immediately and is up in a few seconds. My HD light flashes every little bit, when the computer is up, kinda in synch with the floppy "click". I don't think it does this in ClassicWB which disables the floppy "click", but I am unsure of that. My CD and card reader leds, however, do not flash after the 2091 completes scanning the scsi bus at bootup, with LUNs enabled. I don't know why this is happening. As long as it is working OK, I really wouldn't worry about it. If you are worried, send MECH an email, as he is GREAT at helping out, and stands behind what he sells. He is very knowledgeable with all his products. Hope this helps.
