My installation kernel came with support for only 4 SCSI devices compiled, so simply adding devices wouldn't work for me. After installing my FreeBSD on a SCSI drive set to ID 3, I had to reconfigure kernel to enable support for all 7 devices, recompile it and rewrite some files related to system setup to tell my system to look at SCSI ID 5 for BSD. Then I had to shut down the system, change SCSI ID of the drive with BSD to 5 and boot up. Fortunately I kept my old copies of kernel, because actually I had to reconfigure things back and forth a few times :) Finally it turned out that BIOS on my SCSI card recognizes only the first two drives without additional drivers, so I ended up repartitioning my drive ID 0 to make space for root partition that loads kernel and drivers and then accesses drives ID 2..6. BSDI may come with support for all SCSI IDs precompiled, but if it doesn't you might find above helpful. ---------------------------------------------- -- Artur Jasowicz -- -- arturj@interaccess.com -- -- http://www.interaccess.com/users/arturj/ -- ----------------------------------------------
