So there *was* a problem after all! I saw the exact same things happening to my 1542C (not even using the exact IRQ and DRQ values in userconfig helped). Sounds like this was a real problem. Is somebody going to commit the changes that gfm@mira.net (Graham Menhennitt) provided? If so, will another "official" 3.0 boot floppy be rolled with this change? I ask only because I don't know if using a SNAP or CURRENT boot.flp with the 3.0 CD-ROMs (whenever they get to my door) would be a Bad Thing(tm) or not. Probably not? Right now, the 3.0-RELEASE boot.flp will not pick up Adaptec 154x cards at all. -Jr -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | John Reynolds CEG, CCE, Next Generation Flows, HLA | | Intel Corporation MS: CH6-210 Phone: 554-9092 pgr: 868-6512 | | jreynold@sedona.ch.intel.com http://www-aec.ch.intel.com/~jreynold/ | =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
