Since you cannot boot with the doc2000 installed, I'd recommend trying the 
following, **very carefully**:

  1. Turn off system
  2. Remove DoC from board (I assume it's an ISA/PCI board with DoC socketed?)
  3. Install *empty* DoC board
  4. Boot into DOS
  5. Install latest M-Sys DOS utilities (if not already done)
  6. *** CAREFULLY *** install DoC into socket
  7. Run DFORMAT utility to replace grub firmware

*Disclaimer:  This procedure has worked for me, but it could do *bad things* 
to your DoC.  Use it only as a last resort.

If your machine supports "Network" boot, you may want to try configuring GRUB 
with the "--enable-diskonchip-biosnetboot" option.  This will allow you to 
selectively boot from the DoC, returning to booting from a hard drive or 
floppy when needed.
