Something really strange happened to me last night, and I'm hoping that
someone out there knows how to resolve my problem.

Background:  After removing the old Agnes chip and replacing it with the
new one, cutting the proper trace, and moving the jumper, I then
re-connected the disk drive cable and pluged-in the power supply and
turned everything on to see if it worked.  Nope.

Symptoms:  On power-up DF0:'s drive light turns on and the drive seems
to attempt to find what it needs.  The drive then turns off, and the
screen puts up a display I've never seen before.  The background is
black, there is a white border, and printed *UPSIDE DOWN* are the words
"Amiga Work Bench".  No hand, no color, no "Insert Workbench Disk"
message.  

After trying several different disks and making sure everything was
seated or pluged-in correctly, I decided to try one last item.  I turned
on my external hard drives to see if the system would boot off of them.
Yup.  Everything worked normally, except that the disk icons for both
disk drives either say DFX: BAD or DFX:(random garbage) (where X=drive
number).  Using the <info> command, it tells me that there is either no
disk in the drive, or that the disk is unreadable.  I can't format a
disk, or get the drive to do anything other than turn on for a few
seconds when I change disks.  The last major problem is that NONE of the
disk icons respond to being clicked on.  Even the icons for the hard
drives or ram: drive.

Well, that's my story.  Can anyone help me?  Any hints or suggestions on
what to test or try out before I'm forced to take my baby into the shop
where unfriendly/uncaring hands can molest her?

Thanks in advance for any and all help.
