==================================================

Installing Windows NT 3.51 (Diskette install only)

To install Windows NT 3.51 on a system that has an LS-120 floppy drive as the only floppy drive, do the following:

1. Boot the machine to DOS and copy the Compaq LS-120 Software Support diskette to your hard drive into a temporary directory (i.e. xcopy a:\*.* c:\120 /s).
2. Make a backup copy of your Microsoft Windows NT Workstation 3.51 Boot Disk 1.
3. Place the copy of your Microsoft Windows NT Workstation 3.51 Boot Disk 1 into the floppy drive (i.e. a:). Make an i386 directory on this floppy disk (i.e. md a:\i386). Copy the following files from the temporary directory created in step 1 to the specified target directories on the Microsoft Windows NT Workstation Boot Disk 1:
   • copy c:\120\winnt\ntdetect.com a:\ntdetect.com
   • copy c:\120\winnt\txtsetup.sif a:\txtsetup.sif
   • copy c:\120\winnt\atapidkt.sys a:\atapidkt.sys
   • copy c:\120\winnt\scsiflop.sys a:\scsiflop.sys
   • copy c:\120\winnt\atapidkt.sys a:\i386\atapidkt.sys
   • copy c:\120\winnt\scsiflop.sys a:\i386\scsiflop.sys
   • copy c:\120\winnt\ntdetect.com a:\i386\ntdetect.com
4. Boot the Microsoft Windows NT Workstation 3.51 Boot Disk 1. Press the F6 key when the "Setup is inspecting your computer's hardware configuration..." message appears on your screen. (This is before the blue Welcome screen.)
5. When you are asked if you want to specify a storage device, press S to specify and choose the "LS-120 MB Drive" option from the list.
6. Follow the rest of the installation procedures as outlined in the documentation that comes with Microsoft Windows NT 3.51.
7. When the installation is complete and Microsoft Windows NT is running on your system, open a DOS box and change directory to the temporary directory you made in step 1 (i.e. cd 120).
8. Run CPQINST from this directory (i.e. type CPQINST at the DOS prompt). The software will be installed.
9. Shutdown and power off your computer. When you restart, you will be ble to access the LS-120 Drive normally.
