Well, let's see if I can remember back that far...I think this is how I did it:

First, format drive C and set it to autoboot with the ICD software.  If it is 
already set to autoboot, then copy all files off of the drive because you are
about to erase everything.

Second, boot up pcditto and issue the command FORMAT C: /S
This will logically format the disk and write the system and boot sectors onto
the partition sector (0).  When  finished do the <CTL><ALT><DEL> thing and go
back to the title screen.  Reboot the IBM mode from the hard drive this time to
see if that works at least.  When you have the IBM system booting off the hard
drive then go back to ST mode.

Finally copy your ICDBOOT.SYS back to drive C and now boot the ST to make sure
that works.  Then run pcditto again and make sure that works.  If I remember
correctly, that is how I did it and it works on my system.

Once you can boot off both systems then you can put all your files back on drive
C and continue as normal. 

Oh, one thing...You cannot have a disk in drive A: when booting from the hard
drive in IBM mode, the program will lock up.  However, after the boot cycle is
over, it is wise to put a disk in drive A: and access it, otherwise the motor
will keep running (my drive light is not on, but the motor is running, this 
shuts it off).

If you have any questions feel free to send me mail:
