I have this problem "lsi_sas.sys couldn't be found" launching BartePe image. It works with all RAID-SCSI drivers i put only for lsi_sas.sys. I made several modification in the txtsetup.oem but still this message. I try another solution, i took another sys file from a raid drivers and i renamed it lsi_sas.sys then i don't have the message anymore (of course it doesn't work later) I try version 1.21.8.0 , 1.21.15.0 , 1.21.28.0 but i still have the "lsi_sas.sys couldn't be found" message. Could anyone help me ? EDIT : Finaly i found the problem, i was trying to integrate W2k3 drivers only. I found the Xp drivers and now all is ok !
