Hi,

Using system commander, I cannot boot the 2nd disk, which is
originally as a master disk in another compuetr. The system commander
can recognize the disk. But, when I want to boot the linux on the 2nd
disk. System commander tells me that:
"The partition appears to have a defective boot record or OS has not
been installed yet, and it has been marked as a choice to boot. The
normal boot signature is missing."

So I boot the linux in the 1st disk. Mount the 2nd disk and modified
the liolo.conf. But the problem is still the same. It happens before
the lilo.

The following partition information is get using "fdisk -l". The odd
thing is that the type of the root partition of linux (/dev/hdb2) is
Amoeba (93), instead of Linux (83), while in system commander, the
type of this partition is ext2. Is it the reason that boot record is
not recognized by system commander?

#/sbin/fdisk -l

Disk /dev/hda: 255 heads, 63 sectors, 7299 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System

Are you sure /dev/hdb2 is your Linux boot on the second drive?  You
mentioned that drive #2 was the primary on another machine before
you started this transplant process.. the fdisk output you have here
looks a LOT like that system was a dual boot between Linux and
Amoeba (an experimental OS by Andrew Tanembaum w/similar filesystems
to ext2).  It also makes no sense to me that a root partition would
be on hdb2 rather than hdb1, but to each his own.

I assume you've manually mounted the two partitions to see what's
there.  What's sitting on /dev/hdb1?  You may be making this more
complicated than it needs to be.

Yes. /dev/hdb2 is root (include boot) of the linux OS because I mount
the /dev/hdb1 and /dev/hdb2 with the type "ext2". The directories in
the /dev/hdb1 is not root or boot. It includes something like
application, sorry, I don't remember now.

If you didn't make a boot disk when the second disk was working, remount
it in a machine where it works and make a boot disk.  When you try to
boot off the floppy in the new machine, the only problem is that the
root partition is in the wrong place, a problem that can be fixed by
typing "linux root=/dev/hdb1" at the boot prompt.  Then you can make a
boot floppy with the right boot partition encoded on it.
