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, No, definitely don't commit my patch. All it does is remove the test. It was simply given as a workaround - not a fix!! It will probably break as many machines as it fixes. I'll do a bit more investigaing and try to come up with something a bit more robust. >will another "official" 3.0 boot floppy be rolled with this change?

Right now, the 3.0-RELEASE boot.flp will not pick up >Adaptec 154x cards at all. Strange, the 3.0-RELEASE boot.flp _did_ work for me. It was just the kernel.GENERIC from the bin tarball and my custom kernel that failed.
