Jump to: navigation, search

This example is fixing the dreaded BSOD 0x0000007B stop error on an HP (158A) HP Z620 Workstation using Intel iaStor SAS/AHCI/RAID/IDE, but same applies to anything else.

(This is using the drivers from, DP_MassStorage_wnt6-x64_12121.7z with specific driver path DPx/x64/All/M/Intel/4/ )

Critical Device Database

  • Note although this is in AHCI mode it identifies as RAID with this ClassGUID part e97b
Windows Registry Editor Version 5.00



Windows Registry Editor Version 5.00

"Group"="SCSI Miniport"


And finally copy the iaStorA.sys and iaStorF.sys to c:\Windows\System32\drivers

  • Note you can set the Imagepath as a text string and it still works (or it did in XP at any rate, I didn't try it this time) it is basically points to "system32/drivers/iaStorA.sys"
