md1200 disk shelf

I had a lot of problems getting the fans to spin down. To start with I had to buy a special cable, use these serial settings: RS232, 38400-8-n-1, and update the firmware, replace the EMMs after a failed _boot command.

The most useful commands have been:

_boot > File Transfer > xmodem > send
set_temp <#> <c>
set_speed <%> | _shutup <%>
