Nathan: This isn't really regarding FreeBSD, although I have a Dell 486 running NeXT Step, but IT has an Adaptec 1542c card. I get the same message(s) if the SCSI chain is too long. I think that the spec's say something like 6-9 feet, but the adaptec card likes < 4. That's really not too much, considering most SCSI <-> SCSI cables are 3 feet. My advice is to get those 18" cables and keep your SCSI connections AS SHORT AS POSSIBLE. That has *ALWAYS* solved the AHA timeouts for me. -Roy --------------------------------------------------------------------- Roy Lovejoy PHONE: 619.727.6825 INET:roy@AdeptSolutions.com Pixel PooBah FAX: 619.727.5869 ALINK: ............. adept Adept Solutions PTALK CIS: ........ 72447,1447 524 Avenida Verde DD: 619.598.5225 eWorld: ........ adeptsolns San Marcos CA 92069 AOL: ........ adeptsolns ---------------------------------------------------------------------
