When I go into device manager I have this problem.
Under Hard disk controller I have 2 exclamation marks. The top line says
CMD PCI-0646 Bus master pci to ide controller
The next 2 lines are the ones with the marks
Primary ide controller(single fifo)
secondary ide controller(single fifo)
I have somehow lost my cdrom. It won't show up in explorer or anywhere, although while loading up in the computer it says it's there along with the drivers. I am running windows 98 and have a pentium 200 computer.
