You are the network administrator for Ezonexam. The network includes a Microsoft Windows NT Server 4.0 member server computer that has a non-Plug and Play ISA network adapter.
You want to upgrade this computer to Microsoft Windows 2000 Server. You also want to ensure that you maintain the current device configuration during the upgrade.
What should you do? (Each correct answer presents part of the solution. Choose two)
A. Install the latest driver for the network adapter.
B. Disable the network adapter.
C. Start the upgrade process by using Winnt32.exe
D. Start the upgrade process by booting from the Windows 2000 Server compact disc.
E. Configure BIOS to reserve the IRQ currently in use by the network adapter.
F. Press F6 at the beginning of the text mode setup to specify an additional driver.
C,D 解析：Explanation: WINNT32 is used for upgrades from 32-bit Windows operating systems. You can invoke the program WINNT32.EXE, which is found on the CD-ROM in the I386 folder. This should comply with the requirements of the question since the Winnt32 command will not make changes to the Active Directory configuration or to an application directory partition.
Incorrect answers:
A: Installing the latest network adapter driver would be changing the current device configuration. This is contradictory to what the question asks for.
B: Disabling the network adapter is not what is desired.
E: Reserving IRQs would involve a change in the current configuration which is contradictory to what the question asks for.
F: To install the customized hardware abstraction layer (HAL) designed for the computer that the manufacturer has provided we must press F6 when the Windows 2000 setup prompts us to do so. Thus making use of F6 is necessarily a change in hardware configuration.
