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 driverpacks.net, 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

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\pci#ven_8086&dev_2826]
"Service"="iaStorA"
"ClassGUID"="{4d36e97b-e325-11ce-bfc1-08002be10318}"

Services

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStorA]
"Type"=dword:00000001
"Start"=dword:00000000
"ErrorControl"=dword:00000001
"Tag"=dword:00000041
"ImagePath"=hex(2):73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,44,00,\
  52,00,49,00,56,00,45,00,52,00,53,00,5c,00,69,00,61,00,53,00,74,00,6f,00,72,\
  00,41,00,2e,00,73,00,79,00,73,00,00,00
"Group"="SCSI Miniport"

Driver

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"
