2. Put the Windows NT 4.0 or Windows 2000 CD-ROM into the
CD-ROM drive on the target computer when prompted and
follow the prompts to complete the installation process.
Upgrading an Operating System
Installing to the Same Folder
Installing the new version of an operating system (such as
Windows 9x, Me, or 2000) to the same folder as the existing version
of Windows upgrades your current copy. You will not need to
reinstall applications to use them.
Installing to a Different Folder
Installing the new version of an operating system to a different
folder can enable you to dual-boot (select which operating system to
use at each system startup) your computer. If you want to use your
existing applications with the new operating system, you must
reinstall your applications to the new folder.
Note
If you are interested in building a computer with more than one
bootable operating system, I recommend picking up a copy of
The Multi-Boot Configuration Handbook, published by Que.
Installing to a Different Partition
Installing the new version of an operating system to a different partition
is similar to installing to a different folder, plus it enables
you to use a more efficient partitioning method than if you install
to the same folder or different folder on the same drive. See information
on FAT-32 and NTFS in Chapter 4, “SCSI and IDE Hard
Drives and Optical Drives,” for details.
Checking for IRQ, DMA, I/O, and
Memory Usage
MS-DOS Using MSD
Follow these steps:

1. Start MSD from the \DOS or \Windows folder, or from the
CD-ROM if you are using a version of Windows 9x that
includes it.
2. To see IRQ usage, select Q from the main menu.
