Drive array driver (cpqarray.sys) doesn't start

[Ayman Altounji]

I'm trying to install NT4 server on a Proliant ML370, but the Drive Array driver doesn't start. I followed the Compaq's recommandations to install mass storage devices : firstly, Drive array driver, then IDE CD-Rom ATAPI, SCSI controllers and StorageWorks Integrated Smart Array/42xx/43xx controllers.
I did a diagnosis with Array Diagnostic Utility but no problem has been detected. My disks (2 x 9.1 Go) seems to work correctly ; I can use disk administrator like the Compaq Array Configuration Utility. All seems OK, except the events I receive when I start my server.
I tried to install latest driver version.
I stayed in Service Pack 1.
Thanks for your help.
