Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.89.1i X-Operating-System: FreeBSD 2.2.5-STABLE i386 Sender: owner-freebsd-hardware@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi all.. Here's a little SCSI dilemna that I'm hoping someone out there has solved. The short summary: I need to boot a disk that's hanging off my *second* SCSI controller. Is it possible? Details: I have a Digital PPro that has a built-in NCR53c810 SCSI controller. Normally, I have 1 disk for NT (ID0) and one for FreeBSD (ID1), and they both hang off the NCR controller. I use "bootpart" to copy the first 512 bytes of the 2nd disk into a file on C and then use the NT boot loader to pick between FreBSD and NT. Works great. Enter a second controller. I have a nice new Quantum Fireball 6.5GB disk for FreeBSD. Unfortunately, it doesn't perform as well as I'd like attached to the NCR controller. I came across a 2940UW controller and thought I'd plug it in and hang my disks of it instead. My plan was to keep the CDROM and ZIP drive on the NCR, but the hard drives on the 2940. WRONG! No matter what I tried, I could not get the drives (either of them) to boot off the adaptec. The adaptec picks them up fine and assignes then C: and D:, and says "BIOS installed successfully", but nothing happens after that. Hmmrff. So I switched to plan B, which was to keep everything including the 1st NT drive on the NCR, and just keep my FreeBSD disk on the 2940. NT boots fine, and the adaptec tools under NT find the 2940 and the Quantum drive just fine. Even bootpart sees the FreeBSD drive, and picks it up a a 386/BSD partition type like it always has.. But still, when I try to boot the thing from the NT loader it just won't go... so I'm assuming I have some sort of SCSI BIOS fighting going on that prevents me from booting off the second controller. I even tried disabling the NCR from the BIOS and unplugging any drives on it - still no go, the Adaptec won't let me boot from the drive. So if anyone has any tips on what I should try next, I'd be very happy. When using a floppy to acccess the FreeBSD drive, bonnie and iozone show that Adaptec to be writing over 1MB/s faster than the NCR could to the Quantum Fireball.... In other words, I've tasted the cake and now I don't want to go without it! :-) TIA, -Mark (P.S.
