Hi, I have a compaq proliant and always the same problem. my mouse is not working. as it never worked on the builting ps/2-port i installed a usb -> ps/2-adaptor (HID) . this was working fine, until i had to reinstall my server. since then: doesn't work at all. i indicated also pci=bios-irq for a working mouse.... i have already uninstalled gpm as i heard it does somehow trouble some mices... i've tried already die Protocol PS/2....this makes typing ^A ^20 on the screen... with the config you see below, i can work without mouse without any prob lem. if i touch the mouse, this blocks my keyboard...
