The file you attached works just fine....

you need a zip program such as winzip or (I use) 7zip to extract the files.

First you will need 4 floppy disks to copy the files to when ready.

Download the program and save it to desktop.
create a new folder on your desktop and name it 2000 boot disk
Now right click on the downloaded file and choose to open with (7zip is named if you use it) the zip program you use. choose to extract files and in the window browse to the desktop folder 2000 boot disk and select ok.
In the folder will be the "make disk" program icon....double click it and follow the directions. There must be one of the 4 floppy disks inserted in the floppy drive when you do this!
