The card is a NEC USB controller, which works with my Windows 98 PC, unlike the two VIA USB controllers I tried before (they crashed the PC). A PS/2 to USB adaptor is connected to the USB controller, and provides PS/2 connectivity, if the OS supports the USB controller. Because the PS/2 connection is made through the USB controller. PS/2 is not supported in native DOS or the BIOS, unless your BIOS has USB support. There is an unpopulated USB port on the board. It is shared with the top external USB port. Useful if you need internal USB connectivity. My card came with some very poor USB ports, the plastic was warped and broke easily and the connectors where not gold plated. I replaced them and got a 50% refund.

I've had one of these for several years and it works very well providing you do not want to enter the computer's bios. During the computer start-up the PCI bus and the keyboard is not recognized until AFTER the bios has loaded and you have missed your chance to get into the bios. That being said they are much more convenient and reliable than the cable type attachments that sometimes just cause my keyboard status lights to blink at start-up leaving you no choice but to reboot the computer. I've deducted two stars for its limited utility.
