Document #001

This little trick will remove a Dynamic Disk Overlay from any hard drive.

WARNING:
Running the following Debug program will totally wipe your hard drive's partition away. 
You will LOSE EVERYTHING!

1. Backup all data from hard drive!
2. Obtain a Win98 boot disk.
3. Boot system with boot disk.
4. Run Debug. ( A:\>Debug )
5. Type the following program exactly as written below. Do not type what is in the brackets.

F 200 L200 0
a 100
mov ax,301
mov bx,200
mov cx,1
mov dx,0080 (Note: use 0081 for second fixed disk)
int 13
int 3
(enter a blank line here)
G=100
q

6. Run FDISK & make your new partition.
7. Reboot & Format the drive.
   

No more Dynamic Disk Overlay! Yeah!

I came across the debug program a couple of years ago. This works great.
