Installation

Removed case front bezel to protect acrylic and removed both side panels.

Installed floppy disk drive into the topmost 3.5” bay using four black screws.

Connected floppy power lead from power supply and floppy ribbon cable between main board and drive. The red stripe on the ribbon cable is oriented towards pin 1 of the connectors on the main board (down) and the floppy drive (towards power header).

Later replaced the ribbon cable with a rounded floppy cable. The rounded cable has keyed connectors that only fit one way.

Power On – Booting The First Operating System From Floppy

To test the installation, inserted an old Windows 98 emergency boot disk into the floppy drive and turned the system on.

The POST messages are:

  • No IDE hard disk detected
  • System completed power on self test
  • Computer now booting from operating system

 

The floppy disk drive is recognized as drive “A:”

The Windows 98 startup menu is read from the floppy.

Success! The first operating system is running.
