ReactOS Boot CD doesn't boot to stage 3 with atapi.sys and pciidex.sys from Windows 2003

Tested on 0.4.15-dev-2534-geba00d1.

Steps to reproduce:

• Apply patch: ide_port_enable.patch
• Replace atapi.sys and pciidex.sys from Windows Server 2003 in the output directory
• Rebuild bootcd.iso (make sure reactos.cab is rebuilt too, by touching hdc.inf for example)

Observations:

• Stage 1 pass without problems - stage1-0.4.15-dev-2534-geba00d1.log
• Stage 2 pass without problems - stage2-0.4.15-dev-2534-geba00d1.log
• Stage 3 bugcheck 0x0000007B - stage3-0.4.15-dev-2534-geba00d1.log

Notable difference: atapi.sys takes some time to load on 1st and 2nd stages, however on 3rd stage it loads too quick, maybe it skips something, thus failing.

It's possible to get rid of this debug spam by adding registry key at 2nd stage:

(ntoskrnl/io/pnpmgr/pnpmgr.c:2302) IoOpenDeviceRegistryKey(\Registry\Machine\System\CurrentControlSet\Hardware Profiles\Current\System\CurrentControlSet\Control\Class\{4d36e96a-e325-11ce-bfc1-08002be10318}\0000): Base key doesn't exist, exiting... (Status 0xc0000034)

However it does not fix the boot.
