Vmware and create a Windows 98 virtual hard disk under the Linux File System. The disk size is 2 GB or 1 GB. This hard disk acts as the primary master of the virtual machine, that is, the C disk under Windows 98. Then install Windows 98, IE6.0, and Office2000 on the virtual machine, as well as some common tools such as Ultraedit, Flashget, and Winzip to avoid viruses. Then exit windows 98 from the VM.
