bytes in size. If this is not the case, the function will round the size down to the
nearest four bytes, and remaining bytes will not be sent to the DSP.

DSP.
pProgress Pointer to a structure that will obtain progress reports
during the download. If this value is zero, no progress is
reported.

Prototype
void IFHw::CoffLoad( const char *pcszFilename,
const char *timtype,
PrgssInd *pProgress = 0 )
Parameters
pcszFilename The filename of the COFF file to be downloaded into the
Root DSP.
timtype The type of TIM as define in the file - Sundance.tim.
pProgress Optional pointer to a progress indication object.
14 Mailboxes
The mailboxes provided by the PCI bridge chip allow the host and the Root DSP
to signal each other with information.
Note that mailboxes are intended as a signalling mechanism and not as a way of
passing large amounts of data.
The V3 bridge chip provides 16 x 8-bit mailboxes. These mailboxes are
combined to form two independent 32-bit, bi-directional mailboxes. These
mailboxes are numbered 0 and 1.
