I clean installed a copy of Windows Server 2012 Standard on a DL320S and all seems well except 3 drivers show that they need to be installed.
\VEN_0E11&DEV_B204&SUBSYS_3305103C&REV03\4&205E9EF1&0&22F0 (I may have a few digits wrong ... I believe its the iLO Management Interface Driver)
\VEN_103C&DEV_3302&SUBSY_3305103C&REV00\4&205E9EF1&0&26F0 (I believe this is the iLO2 Management Controller Driver)
\VEN_1000&DEV_0030&SUBSYS_332A103C&REV_C1\5&4C2C194&0&4000E4 (It indicates this is a SCSI Controller, although all drives appear to be working fine)
Are appropriate drivers available?
