What sort of filesystem(s) do you have on da0? If you change $currdev to one of the slices there, can you see what's on them? > # dmesg | grep ahc > ahc0: <Adaptec aic7890/91 Ultra2 SCSI adapter> rev 0x00 int a irq 19 > on pci0.6.0 > ahc0: aic7890/91 Wide Channel A, SCSI Id=7, 16/255 SCBs > da0 at ahc0 bus 0 target 1 lun 0 > da1 at ahc0 bus 0 target 6 lun 0 > (da1:ahc0:0:6:0): tagged openings now 63 > (da0:ahc0:0:1:0): tagged openings now 63 > > The FBSD root is located on da1 (da1s3a) > > When booting, the boot-loader prompt (and hence the environment) > reports 'disk2s3a' which I presume is the equivalent of da1s3a.
