DiskOnChip 16M part OK?

Has anyone used the 16MB DOC (8MB is discontinued) on the PCCHIPS
M810LMR board with the default pcchips config? Or is there anything I
need to change & recompile for the larger part?

Thanks,

As was noted earlier on this list, that keyboard controller part is
"seriously fucked up" on that board.

for now, turn off the keyboard, there's something wrong on that mobo we 
have not worked out. 

Second, write user-mode linux programs to try to get that stupid part to

work, and see what is wrong.

p.s. note I am back, but under really bizarre circumstances, as you can
tell by the line at the end of this note.
