unix not found
If the system displays the
unix not found
message after the system starts to boot,
the unix file is missing. The unix
file contains the bootable image of the UNIX system kernel.
If unix is missing,
you can boot from another kernel file,
(such as unix.old
or unix.safe) by entering the alternate kernel name
If there are no other kernel files
on the system, boot the system from the emergency boot floppy disk set so
that you can restore the unix file:
Insert the boot floppy disk in the drive and reboot the machine.
Boot: prompt, enter:
fd(60)unix.Z root=hd(42) swap=hd(41)
This loads the kernel from the boot floppy disk
and mounts the root filesystem on the hard disk.
If you have changed the location of the swap device,
you should substitute it for hd(41).
Bring up the system in single-user mode
by entering the root password at the prompt.
Unmount the /stand filesystem
(where boot and the kernel are located):
The reason for this is that /stand is normally
mounted read-only and you must unmount it and mount it
again before you can replace the kernel.
Mount the boot floppy disk:
mount -r /dev/fd0 /mnt
While the floppy disk is in the drive, restore unix:
cp /mnt/unix.Z /stand
This copies the compressed unix kernel file from the boot
floppy disk to the hard disk. You do not need to uncompress the kernel.
Before you remove the floppy disk from the drive,
unmount the floppy disk (/dev/fd0):
Remove the floppy disk from the drive
and bring down the system with the
Reboot the system by pressing <Enter> at the
The kernel you loaded from the boot disk does not include any
changes you've made since creating your emergency boot floppy disk set.
You should immediately relink your kernel as described in
``Relinking the kernel''.
Whenever you make changes to your system configuration that add
drivers and relink your kernel, you should create a new emergency
boot floppy disk set.
