SUMMARY
When you install Windows on a new computer, or on a computer containing the latest SCSI or IDE controller technology, it may be necessary to use an OEM device driver to support the new mass storage controller in order to continue with the installation.

Windows Setup may stop with one of the following messages if the controller is not properly detected.

Booting from the Installation Floppy Disks or CD-ROM
Setup did not find any hard disk drives installed in your system

Upgrading Using Winnt32.exe or a New Installation Using Winnt.exe
Stop 0x0000007B Inaccessible_boot_device

NOTE: This behavior may also occur after you update the firmware or BIOS of a supported SCSI controller, which may make it incompatible with the small computer system interface (SCSI) driver included with Windows.



MORE INFORMATION
During text-mode Setup, Windows pauses briefly and prompts you to press F6. This is displayed in the status line, and allows you to use an OEM driver. This functionality for using an OEM driver is limited to installing a driver that is not natively supported or does not match one included with Windows.

If you use a newer version of an OEM device driver with the same name or Plug and Play identifier as a device driver that is included with Windows, Setup ignores the new OEM driver and uses the one included with Windows. This results in the same error message as noted above. If you require an updated OEM driver to support an existing controller that is natively supported by Windows but is not detected during Setup, you must replace the driver contained on one of the four Windows Setup disks or located in the temporary installation folder ($WIN_NT$.~BT) with the new OEM driver. This allows Windows to use the updated OEM driver during text-mode Setup, but you must copy the same updated OEM driver to the final Windows installation's System32\Drivers folder before you continue into graphic-mode Setup.

NOTE: If you choose to format the partition using the NTFS file system during Setup, you will not be able to copy the newer OEM driver into the System32\Drivers folder after text-mode Setup is finished. This behavior occurs because Windows Setup formats the partition with the NTFS file system before copying files. In this case, you can work around this behavior by installing into a FAT partition that is less than 2 GB in size, or a FAT32 partition that is less than 32 GB in size, which allows access using a Microsoft Windows 95 or Microsoft Windows 98 Startup disk. After Windows is finished installing, convert the FAT or FAT32 partition to NTFS using the following command:

convert c: /fs:ntfs
