This motherboard provides six
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 other USB connectors 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.
