If the system can not find the drive, first to observe the POST detects the CD-ROM drive, if the self-test failed to find, because the CD-ROM itself a serious fault is not installed correctly or there is a problem with the data cable, you can "substitution" to confirm. If the optical drive in the process of self can find, but after entering the operating system but can not find reasons for the general software-related. Under normal circumstances, drive under Windows do not need to install the driver. However, in some cases, such as infection with a virus or not correctly installed the motherboard drivers are likely to lead to the phenomenon of optical drive is lost, killing the virus, and reinstall the onboard drive.
Can not find the CD-ROM may also be the IDE controller ports are occupied by lead, you can enter safe mode to remove the IDE controller, after restart, you may retrieve your CD-ROM. Still have questions, together with CONFIG.SYS and AUTOEXEC.BAT real mode CD-ROM driver can be a temporary emergency.
CD-ROM is basically all support DMA mode, but a lot of CD-ROM on DMA support is not good, can not open or does not work properly after opening. To open the drive DMA mode, the best CD-ROM separately connected to an IDE port, IDE port DMA in the BIOS is set to "AUTO", the last to select the DMA option in the "Device Manager" drive properties. The DMA option can reduce CPU utilization when the CD-ROM drive to open the CD-ROM, this point is particularly important to DVDROM and burner, if not open the DMA option will have a significant impact on a DVD player or disc-burning effect . However, individual CD-ROM drive after the opening DMA option may be some compatibility issues, such as can not play the CD, or ripping noise, encountered such problems, please upgrade the motherboard drivers, and update the drive firmware.
