This is kind of off-topic for this list, but I've been working on reverse 
engineering the Windows driver for the MyHD, based on the TL880 chip from 
Oak/Teralogic.  Software that comes in handy: SoftICE (WinDBG might be an 
okay substitute, but doesn't support local debugging and I've never tried 
hard enough to get it running over network, serial, or firewire) and IDA 
(interactive disassembler).  It also helps that MyHD drivers up through 1.54 
have debug symbols enabled, but it's possible to figure out what various 
subroutines do by the functions in the import table (i.e. a good candidate 
for a register write function would be one that calls WRITE_REGISTER_ULONG).  
There's a page on the DXR3 site at SourceForge that talks about reverse 
engineering as well.  If you are lucky enough to find a Windows driver that 
has debug symbols enabled, you can take a higher level approach to reverse 
engineering by reading the disassembly to determine the card's function 
rather than just dumping all register reads and writes.
