You plan to upgrade your computer from Windows NT Workstation 4.0 to Windows 2000 Professional. You determine that the SCSI adapter is not included on the current Hardware Compatibility List (HCL) and that the original SCSI drivers that you used for Windows NT are not compatible with Windows 2000 Professional.You want to upgrade your computer to Windows 2000 Professional.

正确答案 ：B

Replace the SCSI adapter card with a Windows 2000 Professional compatible SCSI adapter. Start the installation from the Windows 2000 Professional CD-ROM. Add the new adapter card drivers when you are prompted.

解析：解析：Explanation: The hardware compatibility list (HCL) is a list of computers and peripherals that have been tested and have passed compatibility testing with the product for which the HCL is being developed. For example, the Windows 2000 HCL lists the products that have been tested and found to be compatible with Windows 2000. Before upgrading to Windows 2000, you should ensure that the computer hardware meets the minimum Windows 2000 hardware requirements. You must also check the Hardware Compatibility List or test the computers for hardware compatibility using the Windows 2000 Compatibility tool. Since the question mentions that the SCSI adapter is not included on the current HCL and that the original SCSI drivers, used for Windows NT is not compatible with Windows 2000, you should get a Windows 2000 Professional compatible SCSI adapter, start the installation of the Windows 2000 Professional CD-ROM and then add the new adapter card when prompted to do so.
