Hi, I am using ATEN KVM switch CS1394, which is a usb keyboard /mouse version. The keyboard can be used in bios setup, but after entering windows, sometimes the switch/keyboard/mouse cannot be detected, but even they can be detected, they cannot be used... Does anyone know the solution? The problem seems does not occur in linux FC4 Thanks. P.S. my computer config: a64 3000+, MSI K8N neo 2 platinum, 2G ram, and aten kvm cs1394 switch. Thanks!!
