This motherboard provides three USB ports to connect USB devices, such as mouse, keyboard, modem, printer, etc. There are
four connectors on the PC99 back panel. You can use proper cables to connect the onboard USB connector to the USB
modules or front panel of chassis. Please note that USB 2.0, with fancy speed up to 480Mbps, is 40 times faster than the
traditional ones. Except for the speed increase, USB 2.0 supports old USB 1.0/1.1 software and peripherals, offering impressive
and even better compatibility to customers.
Note: Please note that if you would like to use
USB devices (Example: keyboard, mouse etc.)
under DOS environment, you must install driver
that comes with the devices to make it work.
