If I boot from a DOS boot floppy with fdisk on it, and type fdisk, I get the error message "No fixed disks" (or something like that). My best thoughts are that DOS doesn't find the array at all. Or that the BIOS (or some other part) aren't remporting its existance. Yet booting from FreeBSD 3.3-Release disks (kern.flp and mfs.flp) allows me to install to the disk da0 and see the dpt0 controller. Why would FreeBSD see it and the BIOS (or other part) and MS-DOS not? > When the system boots, does it find the DPT controller first or the > Adaptec? The Netfinity boot messages list the built-in Adaptec SCSI subsystem and then the DPT card. > If it finds the adaptec first, what's cabled up to the adaptec? Originially, the hot-swap bays. Now, nothing at all. I unplugged the SCSI cables from the mother board and plugged them into the DPT card. > If it finds the adaptec first, does it say "No boot devices found, SCSI > BIOS not installed"? Yes. Unless I set the Netfinity's BIOS to ignore the "planar SCSI". (I've heard that IBM called the mother board a "palar". That appears to be how the BIOS name things, too.) > On the DPT when it boots, isn't there an option to hit a Ctrl-D, and > change a couple settings? If so, double check what they are set to... Yes there is. There's very little there that appears to matter. If I turn on EDBA, it causes the system to change its error message from something like "No disk found or disk reset failed" to something like "No boot sector found". What is EDBA?
