I just replied to another message like this. Here is how to set the
correct root device when you make a boot floppy. It's a shell script.
You use rdev to set the root device.
#
# Created 21-JAN-1995 Richard B. Johnson
#
cp /vmlinux /vmlinux.old
cp /usr/src/linux/System.map /
cp /usr/src/linux/arch/i386/boot/zImage /vmlinux
ROOTDEV=`df / | cut -d ' ' -f1 | sed -e1d`
echo -n 'Setting root device as ' ; echo ${ROOTDEV}
rdev -R /vmlinux 1
rdev /vmlinux ${ROOTDEV}
cp /vmlinux /dev/fd0
psupdate
If you don't want to overwrite your previous boot image do:
#
# Created 21-JAN-1995 Richard B. Johnson
#
cp /usr/src/linux/arch/i386/boot/zImage /tmp/vmlinux
ROOTDEV=`df / | cut -d ' ' -f1 | sed -e1d`
echo -n 'Setting root device as ' ; echo ${ROOTDEV}
rdev -R /tmp/vmlinux 1
rdev /tmp/vmlinux ${ROOTDEV}
cp /tmp/vmlinux /dev/fd0
Once you have tested your new kernel by booting from a floppy. You
might want to boot from your hard disk. It goes like this:
#
# If /etc/lilo.conf is set up right, this will update the bootable image
# on the hard disk presently mounted as the root filesystem.
# Created 21-JAN-1995 Richard B. Johnson
#
cp /vmlinux /vmlinux.old
cp /usr/src/linux/System.map /
cp /usr/src/linux/arch/i386/boot/zImage /vmlinux
ROOTDEV=`df / | cut -d ' ' -f1 | sed -e1d`
echo -n 'Setting root device as ' ; echo ${ROOTDEV}
rdev -R /vmlinux 1
rdev /vmlinux ${ROOTDEV}
lilo -C /etc/lilo.conf
psupdate
I suggest you __ALWAYS__ boot a new kernel from a floppy first. It would
be a bitch to put the wrong boot-image on your hard disk and lock yourself
out (I have several Linux machines so I can always recover... but). I
always boot a new kernel from a floppy first to make sure the machine is
"stable" before overwriting the last image on the Hard Disk.
Cheers,
DJ
