by What is the cause of this message on a new, 2.5 GB, disk : ?

The filesystem superblock is corrupt. Try running e2fsck with an
alternate superblock using the -b option

fsck returned error code - REBOOT NOW!

LILO is not installed yet - the boot is done from a floppy.
The suggestion of running 'e2fsck' had no merit : when the system
re-booted, the superblock was still corrupt. If the message is ignored for
60 seconds, the filesystem mounts and everything seems all right.
Strangely enough, when a root filesystem from another, perfectly sane,
system replaced the troublesome filesystem, the superblock was found
corrupt on the borrowed filesystem - obviously wrong : returned to the sane
system, no complains were issued at boot time.
