uniata: no AHCI support (UniATA/SATA crash)

The problem:

When I boot the cd using my AHCI bios and SATA drives, the setup crashes/freezes after the file copying part, instead of going to phase 2 of the setup.

I tried it over the last months with many trunk builds, but even rev 41183 of today still crashes.

When I choose for IDE emulation in BIOS, the setup does not crash, but cannot write the bootloader to disc at the end of the second phase.

So after several months I am still unable to install ReactOS to real hardware. I have read some people complaining about the same problem in the forums, and since I read that in the last trunk some uniata bugs were fixed, I wanted to report that this one was unfortunately not.
