My particular BIOS (and I'm not the OP) will allow disabling the first or second (pata) ide channel, and/or the on-board sata controller. In the boot order, it gives hd-0, hd-1, ... cdrom, lan, scsi, as options (no sata). With everything enabled, it starts counting disks from the PATA controller, then on-board SATA, then pci controllers, when OpenBSD re-mounts the root fs in rw mode, it counts disks from the outside of pci controllers, then on-board SATA, then on-board PATA. So the root fs that gets mounted rw is not necessarily the same root ro that it was booted from. // George -- George Georgalis, systems architect, administrator <IXOYE>< http://galis.org/ cell:646-331-2027 mailto:[EMAIL PROTECTED]
