To install,

Download the latest BIOS file from HP.

Link: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=15351&prodSeriesId=4248009&swItem=MTX-5f1ea852aba841bc8a9b03e298&prodNameId=4310887&swEnvOID=4064&swLang=8&taskId=135&mode=3

Run installer and follow all steps using a USB flash drive.

Extract my file "AHCI BIOS O41 TheBay.rar" to a folder, copy O41072911.ROM from that folder to the root of your 
USB flash drive.

Overwrite/Replace the existing file on the USB flash drive (should get a warning, if you don't you are doing it wrong).

Eject USB flash drive.

Power down Microserver, put pen drive in and boot up, it should automatically update the BIOS. If it doesn't boot up from it
then you might need to change boot order in the BIOS to the USB flash drive.

Once installed to check whether you are running this BIOS the POST screen should display the following.

-AHCI AVF TheBay.


Instructions on AHCI and other functionality will be details in this thread.
