  1. Hi All, I can't get Windows 7 to boot from my SSD connected to the onboard SATA ports (ODD ports) on my Early 2008 Mac Pro. Here are my specs: Mac Pro 3,1 - Early 2008 2x Quad Core XEON 16 GB RAM Intel 120GB 510 Series SSD Intel 120GB 320 Series SSD (I've disconnected all other drives, including the IDE SuperDrive) Lion 10.7.1 is installed on the 510 Series Intel SSD, which is connected to one of the onboard SATA connectors, i.e. the connectors directly on the mainboard under the fan assembly. The drive is physically installed in the empty ODD 5.25" bay. Windows 7 64-bit (SP1) installed on the 320 Series SSD, which is connected to one of the onboard SATA connectors, i.e. the connectors directly on the mainboard under the fan assembly. The drive is physically installed in the empty ODD 5.25" bay. AHCI activated as per Ludachris/Johnsock approach, i.e. registry hack/MBR modification/Intel RST 10.1... installed with no error messages. Device manager indicates that AHCI is operating normally. Thanks to Ludachris and Johnsocks for their time and effort!!! Problem: Windows 7 will only boot when the SSD is connected to one of the four drive bay SATA connectors. When connected to one of the onboard SATA connectors, I can select the Windows drive during boot up (when holding alt key), but after selecting it, after a few seconds, I get the "flashing folder" symbol on a grey screen. When connected to a drive bay SATA connector, booting to Windows (and AHCI) works fine. I want to use the 4 drive bay SATA connectors for storage and a time machine drive and the two onboard SATA connectors for the two boot drives, Lion and Windows 7. Things I've tried: - Booting from on an onboard port using the standard MS AHCI 1.0 driver, i.e. prior to installing Intel RST application - Swapping the Lion and Window drives connected to the two onboard ports I'd read on various forums that it's not possible to boot to Windows from the onboard SATA connectors on an Early 2008 MP, but I thought that installing AHCI would have addressed that issue. Of course, the other option would be to install the Windows 7 SSD to a drive bay (using an adapter sled) and install the Lion SSD and a 3.5" HDD together into the unused ODD 5.25" bay (I still plan on using the SuperDrive). Would that even work? Is anyone aware of an adapter for installing a 2.5" SSD and a 3.5" HDD together in a 5.25" bay? Thanks in advance for any help!
