I've done quite a bit of searching but was not able to find any issues that I have been experiencing while trying to install Server 2008 R2. From everything I've gathered, it is possible to install 2008 R2 on a PE 2850 but I am running into issues.
I have updated all firmware on the system, Bios, BMC, Backplane and raid card controller. Have successfully configured the raid and initialized the drives.
Now when I try to boot from the 2008 r2 installation CD, I receive the following message:
Status: 0xc00000e9
Info: An unexpected I/O error has occurred.
Note that I was able to install server 2003 and boot into the OS. Anyone have any ideas?
