My DZ77GA-70K with latest BIOS 0049 fails to boot to Windows 7 with any device connected to a non-RAID SATA add-on card.
I have tried both a PCI card and a PCIe x4 card, with exact same results. On startup the BIOS display for the add-on card shows whatever drive is connected to the card, but Windows 7 does not load and this mesage is displayed: "Reboot and select proper boot device or insert boot media in selected boot device and press a key".
If no drive is plugged in to the card, the system boots. Plugging in the drive after Windows has loaded, works with no problems.
The two cards I've tried are:
PCI - Promise SATA300 TX4, which worked without any problem on my DP55KG.
PCIe x4 - StarTech PEXSAT34 SATA - bought new in an attempt to solve this issue.
BIOS display code is '90' with a PS/2 keyboard attached. The BIOS display changes to 'Eb' if I use the same keyboard with a PS/2 to USB adapter (worked on my DP55KG and my wife's Samsung NC-10 netbook) and the PC reboots on its own.
Update: Intel released BIOS 0053 in mid-September. This allows my PEXSAT34 adapter to work, which is great, as it allows me to attach my DVD recorder and IoMega REV70 drive, which the SATA300 did not. Also, my Microsoft USB ForceFeedBack 2 is now working, albeit without the force feedback function. This, I understand, is due to Microsoft not supporting their own hardware under Windows 7.
It is a known issue, you should contact Intel about it. Intel will not offer any support or care about anything that is going on in this community. I've tested RocketRAID 2720SGL and LSI 9207-8i, both failed to boot, so I've contacted them directly, they said they simply don't care. Maybe there's not enough DZ77GA-70K owners to get their attention.
Same problem I have ... I want boot from 4 x SAS HDD RAID - 10
via LSI PCIe x4 AND/OR Adaptec SAS/SATA RAID controller ... NO WAY !
Please help or indicate a possible solution.
