Boot the disk1 CD and select the fixit disk. Then run dmesg and look through the output. You are looking for a device whose name looks something like either ad0 or da0 The number [0] on the end indicates which drive device. All of the disk drives on the machine should show up in dmesg. If you are using a raid controller, the names might be something like mfid0 but still include the da0, da1, ... identifiers for the drives used in the raid. In that case you only want to use the mfid[n] identifier and not the individual device names. Is there a reason you need to know the DIOS device numeric identifier? I have never had to use it for anything. ////jerry > Thanks. > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
