Disable both primary and secondary ATA controller prevent use CD-ROM

Because "synthetic storage driver" not handle CD-ROM devices
( IMHO, even more: Hyper-V host work with CD-ROM only as "PCI bus" device)
Then may be possibility of blocking/hiding specific ATA channels or
devices could be investigated.

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 .
May be instead of splitting filesystem it could be better to boot from
"SCSI" completely and forget about "ATA"? Or there is no option ROM for
SCSI boot in Hyper-V?
