IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:
256986 Description of the Microsoft Windows Registry
SYMPTOMS
If you install a SCSI adapter driver by pressing the F6 key during Setup, and if your computer supports hotplugging or if you insert devices that cause PCI bus numbers to change (such as a PCI adapter with a PCI bridge), Windows 2000 may not be able to gain access to the SCSI adapter, which causes an "INACCESSIBLE_BOOT_DEVICE" message.
CAUSE
If you install a third-party driver by pressing the F6 key, Windows 2000 treats the SCSI adapter as a legacy device; Windows 2000 cannot then handle PCI bus and slot number changes.
RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
260910 How to Obtain the Latest Windows 2000 Service Pack
The English version of this fix should have the following file attributes or later:
Date Time Version Size File name
--------------------------------------------------------
03-Jul-2001 18:26 5.0.2195.3815 380,752 Setupdd.sys
20-Jul-2001 18:51 229,792 Setupldr.bin
20-Jul-2001 18:51 211,216 Setupldr.exe
If you must start Windows 2000 Setup from boot disks, use the following procedure.
NOTE: If you have a Windows 2000 Service Pack 3 Slipstream CD-ROM, you do not need to follow these steps. You can instead boot from the disc to start Windows 2000 Setup.

- Replace Setupldr.bin on Disk 1 with the Setupldr.bin file that is in the hotfix that is provided through this article.
- Replace Setupdd.sys on Disk 2 with the Setupdd.sys file that is in the hotfix that is provided through this article.
- Copy your Windows 2000 CD-ROM to you hard drive (for example, copy it to C:\w2kcd).
- Rename the Setupldr.exe file that is provided in the hotfix as Setupldr.ex_.
- Replace Setupldr.ex_ in the i386 folder (in the Windows 2000 copy that you made to your hard drive in step 4) with the file that you renamed in step 5.
- Create a new Windows 2000 CD-ROM from the version that you copied to your hard drive.
WORKAROUND
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To work around this issue, delete the following registry values:
Key:
HKEY_LOCAL_MACHINE\System\CurrentControlset\Enum\PCI\Plug and Play device ID\Instance\DeviceParameter\Scsiport
Values:
BusNumber
SlotNumber
LegacyInterfaceType
- Shut down the computer.
- Remove the system disk and attach it to a second computer running Windows NT 4.0 or later.
- Start the second computer and log on as Administrator.
- Start Regedt32, navigate to the HKEY_LOCAL_MACHINE hive, and then click to select the root object.
- Click to select Registry\Load Hive.
- Navigate to the System32\Config folder of the installation that experiences the problem. It should be on a drive of the newly attached hard disk.
- Click to select, and then open, the System file in this directory.
- In the next dialog box, type a name for the loaded hive. For example, type SYS.
- Open the following registry subkey:
HKEY_LOCAL_MACHINE\SYS\Select
- Look at the value labeled "Current". This will tell you which control set to use. It should be "1" in most cases, so the control set would be:
HKEY_LOCAL_MACHINE\SYS\ControlSet001
- In this control set, open the subkey:
Replace
Enum\PCI\
Plug and Play device ID\Instance\DeviceParameter\ScsiportPlug and Play device IDwith the actual device ID of the SCSI adapter. - In this key, delete the following registry values:
BusNumber
SlotNumber
LegacyInterfaceType - Shut down the system.
- Reattach the hard disk to the original system.
Since this problem only happens because the number and/or arrangement of PCI adapters has changed since Setup was started, undoing these changes will prevent the problem from happening. After Setup has completed, you can delete the registry entries mentioned in step 12 below. But you should use the following as the base key in the machine registry:
HKEY_LOCAL_MACHINE\CurrentControlSet
There is no need to load a hive in this case.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 3.
