ok, this is a celeron 1.2mhz. pulled a slaved IDE hard drive from my old machine and a stick of ram and shoved it into the box can read the HD just fine, but now the cd r/w is gone. device manager says the driver was installed but can not locate the hardware. I disconnected the new hd, get the same thing. The HD's and the cd rom are on seperate IDE cables. this weekend going to get an exra cdrom and cable and do some troubleshooting. could this be a software/bios issue? something to do with the IRQ's?
