How did you make 'grub.exb'? I haven't written any tool to produce EXB 
files from the Grub images - I only write them to the flash with my own 
doc_loadbios utility.

Load the docprobe and doc2000 modules under Linux - it'll probe all the 
possibilities and tell you where it's mapped in your particular board.

The DiskOnChip firmware is at the beginning of the first flash chip in the 
DiskOnChip. As it's NAND flash, it's not memory-mapped directly.

You _have_ read the NAND flash datasheets, haven't you?
