Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-aic7xxx@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I've had a Micropolis 3387NS Ultra/Narrow drive (drive chip: AIC8325M) working with my NCR-810 SCSI controller. However, I'm upgrading to an Intel Providence MB with an on-board AIC-7880P. It only had a wide (68 pin) connector so I had to get an adapter to my 50 pin (narrow) drive. I been trying to boot linux-2.1.107 using this setup and the drive always comes up with offset 15. I believe this means it thinks the drive is wide. Once it gets to examining the partitions the kernel crashes with a general protection 00. I believe this is because the software thinks it's a wide drive, but it's really narrow. I've tried hacking at the drive to force narrow to no avail and I was wonder if: (a) someone could help me tmp. force all my drives to narrow (since I have no wide drives at this time). and, (b) help me fix this problem "correctly" so this drive get detected by the aic7xxx driver in the proper manner. Also, could it be the Wide-to-Narrow adapter's fault? I was under the impression that this could be a dumb device that just dropped the extra lines. I got it a Micro-Center (i.e. I didn't make it myself), but... Also, I could be on the wrong track altogether. Also, I'm not yet on this mailing list so please cc: any response to: niles@axp745.gsfc.nasa.gov Thanks, Rick Niles.
