Here is my setup. I have two SCSI disks connected to an Adaptec 2940, the first is a Quantum 540MB (SCSI ID 0), containing Windows 95, the second is a NEC 1.5GB (SCSI ID 1) containing FreeBSD: da0 at ahc0 bus 0 target 0 lun 0 da0: <QUANTUM LPS540S 5900> Fixed Direct Access SCSI-2 device da0: 10.0MB/s transfers (10.0MHz, offset 8) da0: 516MB (1057616 512 byte sectors: 64H 32S/T 516C) da1 at ahc0 bus 0 target 1 lun 0 da1: <NEC D3847 0307> Fixed Direct Access SCSI-2 device da1: 10.0MB/s transfers (10.0MHz, offset 15) da1: 1547MB (3170160 512 byte sectors: 255H 63S/T 197C) /home/blaz> df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/da1s4a 31775 15447 13786 53% / /dev/da1s4f 1401271 923795 365375 72% /usr /dev/da1s4e 29727 24415 2934 89% /var /dev/da0s4 528208 162112 366096 31% /dos/c procfs 4 4 0 100% /proc Usually I have os-bs installed on the Quantum so that I can select between Win95 and FreeBSD and this works just fine with the new FreeBSD bootloader for quite some time now. Then I decided to dump Win95 and put some other stuff in, so I needed to boot off the FreeBSD disk directly, without using os-bs. I selected SCSI ID 1 as the boot drive in the Adaptec BIOS. After the kernel boots, I get a panic saying "cannot mount root". I cannot seem to find the right "set currdev" command. When I boot the usual way, currdev is set to disk2s4a, which I guess is right (i.e. it works). When I select the FreeBSD disk as the boot disk, it tries to boot from disk1s4a (which I guess is correct, as the FreeBSD disk is now BIOS drive C:), but the kernel fails to mount root. This is -current as of yesterday, with the latest boot code (installed with "disklabel -B da1" and empty /boot/boot.conf). FreeBSD disk was originally installed dangerously dedicated. Suggestions on how to fix this will be much appreciated.
