You need to download the two ZIP files from the links below. Then, extract them to an easily accessible location, such as your Desktop. Finally, you will need to copy the SCOSW_A.SYS and SCOSW_B.SYS into the C:\SC directory.
You will also need to run the following commands from the run line (Start, Run):
c:\sc\console.exe INSERT=C:\SC\SCOSW_A.SYS,C:\SCOSW_A.SYS
and
c:\sc\console.exe INSERT=C:\SC\SCOSW_B.SYS,C:\SCOSW_B.SYS
Both commands must indicate that the insertions were successful.
