- I recall when I was trying to put as many 3.0 goodies as I could on
- my storage-space-challenged (250 meg) NeXTSTATION Turbo, and I didn't know
- what the hell I was doing. I just got my NeXT a while before and had borrowed
- a CDROM drive to perform the deed, since the 3.0 installation on my hard drive
- was totally minimal. I ended up corrupting the hard disk's file system
- somehow so that it wouldn't boot. After much freaking, weeping, and gnashing
- of teeth, I realised all I had to do was to boot from the CDROM. So I booted
- from the 3.0 CD in single user mode, then completely rebuilt the hard drive.
-
- Now the thing is that I only borrowed the CDROM, and no longer have it.
- So if I do a Bad Thing (tm) that screws up my file system on my hard disk, I
- want to be able to fix it. I am also not connected to an ethernet, so I cannot
- boot from that either. So I want to construct a boot floppy, but I don't know
- how. I couldn't find it in the Sysadmin book or the Sysadmin online docs.
-
- Ok, so I noticed that I had an odmach (Optical) and sdmach (scsi), but
- no fdmach for floppy. I also noticed that odmach was exactly the same as
- sdmach (that is what diff said anyway) and mach which is some weird link to
- something called $BOOTFILE (what is that?)
-
- So I forked one of these on a ED floppy and booted from it. I
- mounted the file system from the hard disk. How do I mount the file system
- on the floppy? (just in case the hard disk's fs is hosed) What files does
- it need? Can I bring it up in single user mode from a sole floppy? Multiuser
- mode? can I fit the necessary utilities to fix the hard disk's file system
- all on one ED floppy?
-
- Oh, and if one forgets the Hardware password, what has to be done?
- I think this might come in useful one day.

- PS. Respond to this group please. I don't get NeXTMail.
- This will hopefully also stop 100 people from answering my question.

- PPS. THANKS in advance to anyone who provides info...
