**        ata标准定义。
**        primary host adapter at I/O address 1FX/3FX 
**        secondary host adapter at I/O adress 17X/37X
**        Each host adapter can have up to two hard drives MASTER/SLAVED off it.
**        1FX  0001 1111 XXXX  Primary Command Registers
**        3FX  0011 1111 XXXX  Primary Control Registers
**
**        17X  0001 0111 XXXX  Alternate Command Registers
**        37X  0011 0111 XXXX  Alternate Control Registers
**
**        I/O Ports //
**        1FX and 17X use same command so we'll use they as a base port + command offset
**
**        For a very complete documentation of these ports and all commands you
**        must read T13 Documentation for ATA 1-2-3-4 etc. etc.,(for example you
**        can read (www.T13.org) d1153r18.pdf (330pag. all on ATA-4)
