Hello, I am trying to install windows home server using oem activation. I believe my problem is that my slp string is incorrect for the oem bios files I am using. My computer is an old HP Pavillion The DMI boot cd tells me my string is HP Pavillion 05. When I try to tatoo it with the Hewitt-Packard string I get an error "Invalid level 2 write access request". I haven't found oem bios files to match my string. Any help would be appreciated.
