When IBM launched the Personal System/2 (PS/2) line of computers, they introduced two major changes:
The 101-key layout added a separate numeric keypad, dedicated arrow keys, and function keys grouped in rows of 12 across the top. This layout became the industry standard. Shortly after, the 102-key layout emerged (common in Europe and other international markets), replacing the right-side Alt key with an Alt Gr key and adding the <>| key next to the left Shift key. pc at enhanced ps 2 keyboard -101 102-key- drivers download
The original IBM Personal Computer/AT (Advanced Technology) introduced the 84-key keyboard with a new 5-pin DIN connector. This was the "AT" keyboard.
Before discussing software, let’s clarify the hardware. The "PC AT" (Personal Computer Advanced Technology) keyboard was introduced by IBM in 1984. Last Updated: [Current Date] Operating Systems: Windows 11,
Both function identically from a driver perspective.
A standard 101/102-key keyboard has no Play, Volume, or Browser keys. If you do have these (common on later "Internet" keyboards), the extra keys will require a driver. However, a true vintage AT/PS/2 101-key board lacks those keys, so you are safe. The 101-key layout added a separate numeric keypad,
The PC/AT Enhanced PS/2 Keyboard (101/102-Key) refers to the standard internal driver used by Windows operating systems to communicate with keyboards connected via the PS/2 port (the round, 6-pin port typically colored purple on the back of desktop PCs).
Unlike USB devices, which often require specific vendor drivers, PS/2 keyboards utilize a generic, low-level hardware interface. If your PS/2 keyboard has stopped working, is displaying a "Code 10" or "Code 19" error in Device Manager, or is behaving erratically, you may need to reinstall or update this driver.
The PC Manufacturer’s Driver Pack
If your PS/2 keyboard came with a prebuilt PC (e.g., a Dell Optiplex with a Dell-branded PS/2 keyboard), download the complete "Chipset Driver" or "Keyboard Driver Pack" from Dell’s support site for that specific model.
