I finally borrowed a ps2 keyboard from a friend to try in the ps2 port and now his keyboard doesn't work! Same response, no functionality, same flickering lights. This tells me that the ports are not only fried, they are lethal. They have killed 3 keyboards.
I just got the SYBA ps2/usb2 PCI card, as previously mentioned. If the ps2 ports are lethal, do I dare install the PCI card? Could these ports destroy the card, if they are still powered?
Someone here asked if the ps2 ports were turned off in the BIOS. I was thinking it would be nice if this could be done to insure the installation of the card., but then again, how do I get into the BIOS without installing the card. What a vicious circle!
