I am attempting to install Windows Server 2012 R2 in EFI mode on an Intel S5520HC for a client. I have updated the BIOS, FRU, BMC and SDR. I have the BIOS set to EFI Optimized boot. I am booting from the optical media in UEFI. The OS sees the RAID Array, writes the partition information to the array and then locks up.
Things I have attempted:
I have pulled the RAID card and attempted to load the OS onto a single HDD plugged directly into the SATA 0 port in UEFI mode, same result.
I have run Memtest 4.20 for 3 days w/o errors.
I loaded the OS onto the array on an Intel S3420GP in EFI mode w/o a problem and then tried to move the array into the S5520HC. The system attempts to boot. It gets to the splash screen where it attempts to load the system drivers and then locks up.
I have attempted to load Server 2012 and 08R2 in hopes I could run 2012R2 as an upgrade once a stable OS was in place. Same lockup problem for those OS in EFI mode.
I have checked the approved OS table for this Mobo and I admit that the only EFI specific OS is Server 08 (not R2).
Is there anything I have not tried to achieve my ends?
Any constructive input is appreciated.
Thank you.
