After a decade, I powered up my old Sony Vaio desktop and got the XP media center edition logon screen. But I can't type my password as my USB keyboard isn't recognized. PS2 to USB adapter isn't working. PS2 mouse is working, but I discarded the original PS2 keyboard a while ago. Wonder what my options are. My goal is to get the old desktop to repurpose as a Linux workstation for kids. Without a working keyboard, how can I boot and wipe out the disk and do anything? Thanks for any help.
