USB Ports question

charlesc09

Hey guys! I dunno if this is an appropriate thread to put in. I am just curious to know. You know most motherboards these days, especially the proprietary ones. The motherboards that come from HP and Dell. There are no PS/2 ports. All USB. What happens if you disable all the USB ports from the BIOS, and you can't access your keyboard or mouse, which are also a USB keyboard and mouse. There are no PS/2 ports on the motherboard like I said. Is their a way you can access the bios and re-enable them?

Some motherboards allow control through a remote access controller (eg DRAG for Dell, iLO for HP). Some allow access through a serial cable. With almost any motherboard, resetting the CMOS will restore factory default BIOS settings and as a result give you back your USB ports.

In my experience, most motherboards still include PS/2 ports. Only small form factor systems have a strong tendency to lack them.

You can always use the clear CMOS jumper to revert back to default.

thanks guys! I was kinda thinking the same thing. Resetting the CMOS battery. I have a HP and Dell computer at home. Both don't have any PS/2 ports, just USB. But ya when I bought those computers at that time, they were on sale. I think around $450-500 CAD. It was better to buy the proprietary ones at that time instead of building my own. But good to know.

Like CyberGuypr mentioned, you could have to reset your BIOS.

You could always snag one of these,
