prevent default OS driver from attaching to emulated ATA controller when Hyper-V

Disable both primary and secondary ATA controller prevent use CD-ROM device in 
VM ( guest)

Because "synthetic storage driver" not handle CD-ROM devices
( IMHO, even more: Hyper-V host work with CD-ROM only as "PCI bus" device)

Removing our ATA patches, on the other hand, results in a huge
performance loss. This is because the root file system is managed by the
ATA driver, which is emulated under Hyper-V.

Place on IDE disk only "\boot" ( and bootloader), other on SCSI .
