I can't be 100% sure on that, but it might be worth a try. > Yep, I have to set root_disk_unit=1 (I assume that's what you mean, I'm not setting rootdev) in my /boot/loader.rc, but the loader can't find the loader.rc file or the kernel until I set currdev=disk2s1a. Here's what I've got in /boot.config: 1:sd(0,a)/boot/loader and /boot/loader.rc: load /kernel load -t userconfig_script /kernel.config set root_disk_unit=1 When I let the machine autoboot, it goes through the primary and secondary boot phases just fine. In the third stage, I get the following: Booting [kernel] Can't load 'kernel' Type ? for a list of commands, 'help' for more detailed help. disk1s1a:> If I then run the following commands: disk1s1a:> set currdev=disk2s1a: disk2s1a:> include /boot/loader.rc disk2s1a:> boot The kernel and my config file load and the kernel boots successfully. So you're right about setting root_disk_unit, but I can't get that far in an autoboot. > > I've got a system with one IDE drive and two SCSI controllers, one Adaptec > > 1542 and one Adaptec 2940.
