Bios problem my bios settings was set to default by mistake.after that my computer cannot detect any IDE devices.how can i solve that problem.

Restart your computer during the boot process you will a certain key to press to enter set up usually the Delete or F2 key this will vary depending on your operating system and computer Press and hold that key during the boot up process to enter BIOS using the arrow keys navigate to Advanced Bios features press enter you will see the boot order Change the first boot device to your hard drive.
The BIOS is AMI. Under ADVANCED SETUP:
The options listed for 1st,2nd ,3rd Boot device include:

IDE-0 means Pri master ?
IDE-1 means Pri slave ?


IDE-2 means Sec master ?
IDE-3 means Sec slave ? If you are unsure or have made mistakes you can load optimised or failsafe defaults this will automatically set the boot order Hope this helps.

Once your powered on the CMOS battery is no longer an issue. If it isn't reading the IDE or SATA channels it could be because they are not set in the BIOS. Check your BIOS setting and double check your cable connections. You also need to make sure, for IDE devices, that one of the drives is set to Master and the other to Slave otherwise they confuse the board and cancel each other out.

Each PATA device (disk-drive or CD/DVD) drive has some small jumpers.

For the two devices connected via the one ribbon-cable,
set the jumpers on one device to the MA(ster) setting,
and set the other device to the SL(ave) setting.

Or, set both devices on the one cable to the C(able)S(elect) setting.

When properly set, both devices will be quickly and properly detected.

Be sure that your BIOS SETUP has been configured to allow SATA devices,
i.e., not set to "disabled" mode.

set your computer's BIO settings to default through the F2 button then connect the IDE fast and make sure its the master with an Operating system on it then connect the SATA after the IDE has been detected.

check whether the powe plug has been inserted properly and the power plug is working fine. Even though if the power plug inserted is working fine and CD ROM not detecting means CD ROM was damaged.

Shut down the computer.Disconnect the ide cable from hdd .Just connect using primary hdd and boot the computer. Shut down the computer. Connect the secondary hdd both IDE and power cable. Restart the system and go to bios . Check if the both hdd are detected in bios. If detected boot to desktop. If not detected reset bios settings to default.Restart computer and check. IF still not detected shutdown computer.Disconnected secondary hdd and primary hdd,connected secondary hdd to primary ide connecter and check in bios. If still not detected try connecting secondard hdd on different computer and check.

Once you reset the bios everything goes to manufactures default settings. You will need to make some changes within the bios. You'll need the help of the manual. See page 3-20.
If your operating system is loaded on to the ATA IDE drive make sure you set bios settings as follows:
Connect the ATA IDE to MB primary master IDE port.
Connect the ATA SATA drive to the MB's first SATA port.

ATA Configuration
Set as, [P-ATA+S-ATA]
S-ATA Keep [Enabled] Set to [Yes] This enables the SATA controller.
P-ATA Keep [Enabled] Set to [Yes] This enables the IDE controller.
On-chip IDE configuration, "ATA Configuration = [P-ATA+S-ATA]".
Next go to Boot menu. Make sure the ATA IDE drive is chosen as boot device three.
First boot device [Floppy] (If you have a floppy disk drive connected.)
Second boot device would be [DVD/CD-ROM] drive. This should be connected to the MB's secondary IDE port & the DVD/CD-ROM drives Master/Slave jumper, set to Master.
Third boot device [ATA IDE drive]
If your boot drive is the SATA drive than set: third boot device to the SATA drive.
(Hard disk drive with operating system loaded on it).
Save your changes & exit the bios.
Keep in mind all ATA SATA drives are seen as Master drives. SATA drives are seen by the SATA controller & in order by their connection to the SATA port number.
Save & exit the bios. The system will auto restart. Windows should start.

after pressing f2.....bios setup was opened.....go to drivers.....and than open diskette driver.....select off .....your problam is solve 1000%

BIOS Try setting the BIOS settings to Auto detect any IDE Devices. POWER Try using a spare Molex Power Connector IDE CABLE Try using a space IDE\SATA Cable. Make sure all are properly locked down into the sockets. (Mobo and HDD) SOUNDS and VIBRATION Since all HDD's are mechanical devices they produce sounds and vibration. Make sure they have this else its a powre problem or your HDD is defective. ====================== If you are having trouble with Newly bought items save your self from headaches by returning them and demand a replacement or a refund!
