I’m in the process of putting together a computer to give to someone. The system is an older Pentium II, 500MgHz, 512 RAM, IBM 300pl. Im trying to install my Sony DRU-510A DVD-RW into the system. The Bios won’t acknowledge the drive is there at all. Sony simply offers a firmware that runs within Windows that works from the drives your computer acknowledges. I don’t have the original disk to install (can’t seem to find it.) Any ideas of how to get the computer to recognize it and then install it? Would appreciate your help. Thanks in advance.
