   Will have to do more digging to figure out the Read/Write Sector Buffer   
   structure (and yes the commands are in a reversed order compared to the   
   other read/write ops - the RD bit confirms this.)   
      
   Not sure what the cmd. 12h is, but it's definitely implemented. The   
   ESDI-era Int 13 AH=1Ch iface may reveal more context.   
      
   Will have to czech the refdisk/diag utils too, as these are more likely   
   to use undocumented SCSI SCB commands.
