Jumper setting - LG GDR-8164B DVD Drive

Warning: Incorrect settings may produce undesirable results. Please research thoroughly before making any changes.

You can set the jumper as follows:

Clearing the BIOS settings
CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
This motherboard has jumpers to clear the Real Time Clock (RTC) RAM in CMOS.

Clearing CMOS

To clear CMOS, follow these steps:

1. Temporarily set jumper Clear CMOS (CLRTC) to pins 1-2.
2. Wait 5-10 seconds and then return the jumper to pins 2-3.

When you startup the PC you will need to enter BIOS setup to reset any custom BIOS settings.

Clearing the BIOS password

The BIOS password is used to protect BIOS settings from unwanted changes. If you have forgotten your password you may disable password checking.
To erase the BIOS password follow these steps:

1. Turn OFF the computer and unplug the power cord.
2. Locate the jumper labeled Clear P.W. The jumper is found at the lower right edge of the motherboard.
3. Move the jumper on jumper Clear P.W. to pins 1-2.
4. Plug the power cord and turn ON the computer.

Hold down the F10 key during the startup process and enter BIOS setup to change or clear the password.

After changing or clearing the BIOS passwords, remember to reset the jumper to pins 2-3.

Product information

SP = Spare (Slave)

Hope it helps.

If this is an IDE/PATA hard drive then the jumper settings are marked on the circuit board.
MA = master
SL = slave
CS = cable select
If this hard drive is the one installed on the Primary IDE controller the the jumper has to be set to Master. If it won't boot up then the jumper needs to be set to Cable select.

If this hard drive is a second hard drive and is connected to the 2nd connector on the IDE data cable that is connected to the primary IDE controller then the jumper must be set to Slave.

If this hard drive is a second hard drive and is connected to the secondary IDE controller and there is no other drive on the IDE data cable other than this hard disk the the jumper can be set to either Master or Slave.
If there is a CD drive on this cable too then the drives on this data cable then the jumpers on each drive must be set differently, they cannot be set the same jumper setting.

hello

go to this link.. it will illustrate jumper setting

http://sysdoc.doors.ch/MAXTOR/diamondmax_30_vl_ultra_ata_66_quick_specs.pdf

if you want to boot from this drive, please set the jumper to the master position.

if this drive is for additional storage, please set the jumper to slave. and make sure 1st hard drive is set to master.

if this is the only drive in the system, please set the jumper to single or remove the jumper.

there will be a chart telling you which pins are for which setting in the jumper area, which is between the data plug and the power plug on the back of your HDD.

main thing that will cause drives to not work is 2 jumpers on the same cable and they both are set to the same thng.. i.e. master/master or slave/slave. also, if one is set to single drive it will likely bypass the slave drive.

here is a poster of Maxtors jumper settings for each kind of drive.

Please look on top of your HD and u will see a table that show u the HD jumper setting (Master, Slave or Cable Select).
Then look again the rear side of the HD and u will see some pin that locate beside the power input of the HD, that is the jumper pin.

Now set the jumper according to your requirement refer to the jumper setting table just now. To set it just unplug the jumper (look like a U shape contactor covered with plastic) and plug it back according to the requirement. Sometime u may lost the jumper contactor, nevermind just use what ever conductor cable to roll between the two pin and make sure the pin is connected that all.

For use as slave there is no jumper connected. (Master on/slave off0

why are u trying to set the jumpers ? i should have thank u if u add some more details. all the jumpers onboard have their own purpose. look carefully on ur mainboard, u'll see the jumpers with their distinct labels.
