Table  129 Write DMA Ext Command (35h)   
The Write DMA Ext command transfers one or more sectors of data from the host to the device, 
then the data is written to the disk media.  
The sectors of data are transferred through the Data Register 16 bits at a time.  
The host initializes a slave-DMA channel prior to issuing the command. Data transfers are 
qualified by DMARQ and are performed by the slave-DMA channel. The device issues only one 
interrupt per command to indicate that data transfer has terminated and status is available.  
If an uncorrectable error occurs, the write will be terminated at the failing sector  
Output Parameters To The Device  
Sector Count Current 
The number of continuous sect ors to be transferred low order, bits (7:0).   
Sector Count Previous

the Sector Count register is specified, then 65,536 sectors will be transferred.
