When's the last time you saw a new PC that uses a PS2 connector for the
keyboard? Fifteen, twenty years? They didn't send anything wrong,
she's just confused or trolling.

Some do have them, although it's better to use USB. Use any port
(although you might want to avoid USB3, usually with blue plastic in the
connector).


For a while I thought that USB ports did't work until after Windows
started, but PS-2 ports and the larger round ports that preceded them
worked before Windows loaded. As soon as the BIOS ran.

Now I think I'm wrong, but was there ever some truth to this?

Since you can boot from a USB drive, I'd say the answer is a definite no.

It works if the BIOS supports it. That was certainly not forever. The
original machines with onboard USB 1 would support a mouse before the
drivers loaded but booting a USB drive came about the time of USB 2.
With Windows 98SE, you can use a mouse with no problem but you need
the driver to run a storage device. There may have been an update that
picked that up but it is not on my Latitude lap top.
