i just bought a KVM switch today which is a cool thing because itll let me use both my Mac and Windows Destop at the same time but heres the problem. Its a VGA and PS/2 only KVM my G4 will have ADC/DVI so heres where 2 problems will come in. I have found this PS/2 Card this is just one option as i like the idea i get 2 extra USB 2 ports with it. It uses the NEC Chipset for USB (Which ive been told NEC chipset works in macs) and the PS/2 uses the Chesen Chipset. My second issue is my KVM is also VGA is there a VGA to ADC adaptor? i really dont want to give up my DVI connector for a VGA adaptor because i use DVI on my monitor but i am not sure if i can use a Keyboard/Mouse through the KVM with no video connected.
