Table 130 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 sectors to be transferred low order, bits (7:0).   
Sector Count Previous  The number of continuous sectors to be transferred high order bits (15:8). If 
0000h in the Sector Count register is specified, then 65,536 sectors will be 
transferred.
