I have read a aritcle saying that :
"A computer must be configured to support BitLocker prior to installation of Window 2008. eg. Create a separate 1.5Gb partition, formatting it and making it active as the System partition prior to creating a larger partition, formatting it and then installing the Window Server 2008 operating system"
However, how does it work on a HP Proliant G5 server ? How can I create a 1.5Gb partition without a OS installled, and the RAID card driver couldn't be recgonized. I have installed the Window 2008 and it could install succesfully, but really don't know how to configure the partition without a Window 2008. Please advise further.
