amdprophet Posted June 1, 2006 Share Posted June 1, 2006 I've read through most of the forum searching for a fix, but I just can't find one. I've got a DFI LanParty UT nF4 Ultra-D and my PS/2 keyboard will not work. I've got a USB keyboard that does work, but I hate it and I'd rather use my PS/2 keyboard. It didn't work during the setup when I tried to install OS X natively either. I had to install through VMWare, then reboot to find out it wouldn't work after OS X was installed. Anyone have the same board as me and have PS/2 devices working? Link to comment https://www.insanelymac.com/forum/topic/18817-solved-ps2-keyboard/ Share on other sites More sharing options...
gee Posted June 1, 2006 Share Posted June 1, 2006 You can't use a PS/2 keyboard with a USB mouse. Plug your mouse into a PS/2 socket (USB->PS/2 adaptor) or stick with your USB keyboard.

amdprophet Posted June 1, 2006 Author Share Posted June 1, 2006 I used to have a PS/2 mouse with my PS/2 keyboard and that didn't work either. Link to comment https://www.insanelymac.com/forum/topic/18817-solved-ps2-keyboard/#findComment-123198 Share on other sites More sharing options...
bluedragon1971 Posted June 1, 2006 Share Posted June 1, 2006 Then buy one of those adapters that allows you to use a PS/2 mouse and keyboard on a USB port. They are usually less than $10 or so. Problem solved. I'm using one right now. Link to comment https://www.insanelymac.com/forum/topic/18817-solved-ps2-keyboard/#findComment-123271 Share on other sites More sharing options...

amdprophet Posted June 2, 2006 Author Share Posted June 2, 2006 I think it matters on the chipset you are using. What kind of motherboard do you have Rhinox?

pip11 Posted June 2, 2006 Share Posted June 2, 2006 At least for me (Shuttle ST20G5, weird ATi/ULi chipset), you need to have both a PS/2 mouse and keyboard connected at boot, or no PS/2 devices will work. Just having a PS/2 keyboard plugged in but with a mouse on USB will result in no keyboard.

gee Posted June 2, 2006 Share Posted June 2, 2006 PS/2 Microsoft Internet keyboard + USB Logitech mouse = didn't work for me PS/2 .... + PS/2 Logitech mouse (adaptor) = worked It's been noted at least one other time on this forum, whence my mistaken belief. Seems to be a motherboard-specific issue. Intel 875P.

amdprophet Posted June 14, 2006 Author Share Posted June 14, 2006 I fixed it. I just did the /etc/rc edit which I found in another post. To fix it, just do the following: Open Terminal sudo su root nano /etc/rc Keep hitting ctrl + v untill you get to the bottom of the page insert this before the fi and the exit: kextunload /System/Library/Extensions/ApplePS2Controller.kext/Contents/PlugIns/ApplePS2Keyboard.kext kextload /System/Library/Extensions/ApplePS2Controller.kext/Contents/PlugIns/ApplePS2Keyboard.kext After you do that just reboot and your keyboard should be working.

This sounds great, but how do I get to a terminal? It is my first time running, and I get stuck at the registration screen, because I have no keyboard input.
