The installation of two CD-ROM, can not be identified

Previously, only a DVD burner, and now a plus, but even the two red light can not be identified, how the matter ?????

light in the back look at the human body, jumpers, jump on the wrong found.If the jumper is not no line.spent a few lines of data? ago and if the hard disk with a line Plus the District of light on the use of the other slots, not at this time jumper, and if so, remove him.Two-set CD-ROM:
will drive one of the jumper cap MASTER inserted, and then in the next IDE at the end of the line, the drive to another jumper to cap the SLAVE, the IDE from the middle line (behind the drive marked C, M, SC is CABLE, automatic settings from the Lord, M is a MASTER, CD-ROM-based settings, S Is SLAVE, is set to drive from).In general, then you can use.

One or two-installed CD-ROM
the premise of the new equipment will be the first to have space.Hard drives are IDE interface with the equipment Now the computer normally have 2 EIDE interfaces, which can be accessed by 2 pairs of the largest of the 40 core plug hard line linked to 4 IDE-compatible devices.Therefore, if you have a computer with no increase in the other IDE interface device, There should be enough space left to a second hard disk or CD-ROM.

Second, we must be careful in case the size of power supply.Due to a number of old-fashioned machine provided by the power output is often only about 200W, together with Many people purchase their own and then fitted with a number of other new equipment, such as the type of VOODOO card, network card, the full capacity of the old power supply for the new drive is able to provide sufficient output power of the very questionable.Do not Look down on this issue, the consequences can range from death, then re-make you drive in advance of the glorious “retirement.” Therefore, it is best to replace your power supply 230W or more.

You should pay attention to the final The motherboard BIOS support Ultra DMA device.Because of the high-speed drives have been fully supports the Ultra
DMA standards.And if they play the speed advantage to be an effective board.Reason, Ultra
DMA standards have been out for more than two years, and now the board is not a problem.
Second, the installation of pre-planning and the correct jumper settings

?
the installation of the first Second optical drive:CD-ROM will allow new and the old one after another to share the other IDE drive interface, and DVD burner for the main disk, CD-ROM set from the old disk.(See concrete ways to set up panel on the drive that China and India Text or graphics)

three or installation of fixed
good jumper off the right set up a new hard drive or CD-ROM, plug the power cord and data-line.Mistake generally will not play because of power Lines are often part of the joint design for the special shape, it is wrong not to play into.And the data line on the side of colored markers (black or red), and digital interface or a small triangle logo, so as long as 2 pairs Will not be on the wrong plug.In addition, for users to install a second CD-ROM, CD-ROM and sound card to connect the line sources can be pulled down and replaced with a new drive.Even though these, the tight screws can be power-related projects for CMOS The set.
Four, after the installation of the operating system debugging
due to the WINDOWS plug-and-play support for new equipment, so generally speaking, the new equipment will be correct identification.The new drive, and often do not have to Another driver can be installed in the WINDOWS under normal use, of course, if the net ready to use it under DOS, you need to install the driver brought the original.But normally does not mean that the work has to play out the potential of new equipment.Therefore, it is necessary to carry out the set in WINDOWS.However, the motherboard does not support DMA-player mode, this could be the province of the following steps.

For WIN98 with the players, as a result has been WIN98 On the built-in Ultra
DMA support, so unusual setting up simple:enter as long as “the beginning” – “settings” – “Control Panel” – “system” – “Device Manager” to find the additional drive, Double-click to open, and then point “set up” in the “DMA” option to play on a hook, then prompted to restart the line.

For WIN95 OSR2 with the player, set up on the relative Some of the trouble.Because it must be installed on the motherboard manufacturers to provide Bus
Master driver to the WINDOWS to patch up the system, the system can provide a good Ultra
DMA support.(But before the operation to back up the registry and CONFIG.SYS and AUTOEXEC.BAT file to prevent any eventuality)
concrete steps are as follows:(TX430 to a joint inquiry board, for example)
? With the insertion of the board bring with Bus
Master driver floppy disk.Double-click SETUP or implementation of the INSTALL file (as a result of a specific site to another) and then prompted to delete AUTOEXEC.BAT and CONFIG.SYS all of the real-mode IDE device driver (CD-ROM driver for more), select YES after the copy paper, after the completion of the Restart.

? after the resumption of construction of the new hardware information.And in accordance with selected drivers will be prompted to store the path:C:\ WINDOWS \ SYSTEM \ IOSUBSYS, Kaoru process, followed by installation of “Primary
Bus Master IDE controller “,” Secondary Bus Master IDE
controller “, restart again, the system automatically constructed driver, the installation is complete.
following the work done in line with the WIN98, to find the corresponding “DMA” option and play hook, restart the computer to enjoy the DMA mode brings a sense of the speed upgrade.
Have to be careful:As the Bus Master driver to take over all the IDE interface device drivers, so Most likely cause was an old hard disk drive or older (do not support Ultra
DMA mode) not working properly and even “disappeared” by modifying the registry at this time can be to make use WINDOWS bring their own standard IDE driver to replace some of the Bus Master fell to the driver.As follows:

in the “start” menu, select “Run” dialog box, type in “REGEDIT” and return to start the Registry Editor.Window on the left click ” HKEY-LOCAL-MACHINE/SYSTEM/CURRENTCONTROLSET/SERVICES/CLASS/HDC “, each of the four branches to open its” 0000,0001,0002,0003 “,

old equipment in the vice-IDE interface (that is, No.Second IDE interface), then open the branch as a key “SECONDARY IDE
CONTROLLER” where the branches of the “0004”, in the same position to do the same changes.To determine, from the Registry Editor and restart the computer will All of the normal.
