SYMPTOMS
During the Text-mode portion of Setup, some Integrated Device Electronics (IDE) drives are reported as being only 8 gigabytes (GB) in size. This behavior can occur with any IDE hard disk that is larger than 8.4 GB in size, but should occur only on models that report 15 heads.

If Windows 2000 Setup is upgrading Microsoft Windows 98, Setup may stop responding (hang) or display the following error message:

STOP 0x0000007B

INACCESSIBLE_BOOT_DEVICE



CAUSE
If the drive reports 15 heads, Windows 2000 uses the Cylinders, Heads, and Sectors (CHS) method to determine the drive size. Instead, Logical Block Addressing (LBA) should be used in most of these cases to determine the actual drive size. This does not occur with drives that report 16 heads. In this case, LBA is used.



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:

Instructions for Installing the Hotfix
NOTE: These instructions are for single-computer installations from a CD-ROM. This does not apply for upgrade scenarios (refer to the following "Upgrade" section).  Create the boot disks.For additional information about how to create boot disks, click the article number below to view the article in the Microsoft Knowledge Base:

197063 How to Create Setup Boot Disks for Windows 2000

 Replace the Atapi.sys file on disk 3 with the Atapi.sys file included in the hotfix. To extract the files, use the /x command-line switch with the program file. (This is the Q254769_2k_sp1_x86_en.exe file.) Start Setup by using the four boot disks. This should allow Setup to see the entire drive and complete successfully. Because WFP runs at the end of GUI-mode Setup, the Atapi.sys file is replaced. After Setup is finished, you need to reapply the hotfix again to make sure the correct file is in place.

For an Upgrade Scenario

 * 1) Start Setup by using Winnt32.exe.
 * 2) At the first reboot, you need to boot to a bootable disk and replace the Atapi.sys file in the C:\$win_nt$.~bt folder. To extract the file, use the /x command-line switch with the program file. (This is the Q254769_2k_sp1_x86_en.exe file.)
 * 3) Start Setup by using the four boot disks. This should allow Setup to see the entire drive and complete successfully.
 * 4) Because WFP runs at the end of GUI-mode Setup, the Atapi.sys file is replaced. After Setup is finished, you need to reapply the hotfix again to make sure the correct file is in place.

For an Operating System Deployment Share (Network Share Point)
 Copy the hotfix to the distribution share and rename the original file to Atapi.org.</li> Using a Cmdlines.txt file, add the following section:

[Commands]

"Hotfix.exe -m -q -z"

NOTE: Currently, this is Q254769_2k_sp1_x86_en.exe, rather than Hotfix.exe</li> Copy the Hotfix.exe file (Q254769_2k_sp1_x86_en.exe) and all related files to the $oem$ folder of your distribution share.</li> Make sure the following section is in your answer file:

'OemPreinstall = Yes'

</li> Run Setup from this share using your unattended answer file.</li></ol>
