Bootup Disaster (post-upgrade?)

["Alan E. Davis" <adavis@saipan.com>]

Updating sid.  A screen is presented at Lilo.  Did I want Lilo to
access the HDD as LBA?  This was mentioned as probably desireable.

Now I reboot.  The boot process begins.  After the BIOS readouts, up
comes Lilo.  But no!  THis is what I see:

    LIL

then a pause.  Then continuing:

   LILLinux02 ^^^

Now the machine goes berzerk.  The drive starts thrashing/clicking.

[A friend tells me there are now viruses that can attack the hard
drive this way.]
I will try to install a new boot record using install disks from
Testing.

Meanwhile, does this ring a  bell?
