|According to info on the web your XENIX keyboard first came out circa 2004 and it has a PS/2 connector on the end of it's cord|
(It's possible that it was also available with a USB connector on the end of it's cord but I found NO mentions of that.)
If your keyboard's cord has a PS/2 connector on the end of it's cord........
I found a post on the web that indicates it's probably NOT a "combo" keyboard that is wired up so that it can be used with either a PS/2 port, or a USB port when you use a simple PS/2 to USB gender adapter.
He got an unrecognized USB device message when he tried using a simple PS/2 (female) to USB (male) gender adapter with it.
If you've had the keyboard since it was new, if it didn't come with a simple PS/2 to USB gender adapter, it's NOT a "combo" keyboard.
If it DID come with a simple PS/2 to USB gender adapter, it was probably purple. A green gender adapter for a "combo" mouse will probably NOT work with the keyboard.
Keyboards do NOT require drivers for their standard key functions. Windows installs generic drivers for the keyboard for those functions automatically.
If there are drivers for them, they're only for the functions of their non-standard keys and buttons - installing those is always optional.
In your case, it came with a floppy disk which contained drivers for Windows 95, 98 and NT. The NT drivers probably work fine in 2000 and XP.
If your computer has a PS/2 port and your keyboard's cord has a PS/2 connector on the end of it's cord, the keyboard should be recognized fine if you plug it into the purple PS/2 port, or if it has only 1 PS/2 port, into the combo PS/2 port (if you need to plug in both a mouse and a keyboard, use a standard Y adapter meant for laptops with the port - two female PS/2 connectors to one male PS/2 connector.

If it has no PS/2 ports, you COULD use the purple USB port in a two PS/2 (female) connectors to one USB (male) connector adapter that has circuitry between the connectors plugged into a USB port.
