- I had a misfortune to train thourougly booting from other devices than
- a default sd0 :-).
- The following procedure works consistently for me (assuming here that
- sd2a, say, contains all files necessary for booting in a multi-user
- mode). Some steps are obviously for situations when you cannot boot
- from sd0a and changing ID's is not an option for some reasons.
- a) Boot from floppy (you have boot floppy, don't you?) in a single
- user mode and modify /etc/fstab on your intended boot device
- to mount the proper file system and not sd0a. In our sample
- resulting line will be:
- /dev/sd2a / 4.3 rw,noquota,noauto 0 1
- instead of an original
- /dev/sd0a / 4.3 rw,noquota,noauto 0 1
- To get an access to this file you will have to mount
- ( say '/usr/etc/mount /dev/sd0a /tmp/hd') manually.
- Use -n option and writable directory if you are booting
- from CD-ROM or from floopy which starts CD-ROM.
- BTW - can somebody tell me how to use 'remount' option.
- Is not documented on 'man-page' and always barfs on me.
- b) Go back to monitor and 'halt'.
- c) At 'NeXT>' prompt type 'bsd(2,0,0)-a'. This means 'ask
- for root device'. An option 'rootdev=sd2' never worked for me.
- d) When asked for root device type 'sd2' and hopefuly you are
- back in business.
- e) Restore /etc/fstab to a pristine state. You will likely
- forget that later and in that case you may start the whole
- procedure once again from scratch. :-)
-
- Lets hope that you will never have to use that knowledge.
