Recently I was trying to install Longhorn Beta Version on my PC (Athlon 64 3000+ & MSI RS482M-ILD). I tried to do a fresh installation of Longhorn on my existing XP with SP2 platform. After running the installation shield for few moments, the installation prompted me to restart. After restarting thesystem failed to recognize my keyboard as not a single key was working. To the horror I am not being able to enter into BIOS as delete key is non-functional. Also I can't boot from CD as again it requires any key to be pressed. Nor the longhorn installation continued. The bar is moving on the boot screen showing Longhorn but nothing follows. I tried different keyboards but no use. So either it is a Keyboard Port problem or my BIOS is corrupted I don't know. Can anybody help what the hell it is. I don't know whether it is a software problem or a hardware problem. So I posted this in both.
