Bios password for foxconn h61mxe


open up the case and look at the mb, look for cmos reset, you need to turn off the computer use the jumper to short out the board, when the jumper is in place turn the computer on let the system boot up than shut the system down remove the jumper, restart the computer.
if that fails you could try removing the back up battery on the board.

maybe try removing the battery on the motherboard first before resetting the cmos.

DG31PR backdoor bios password


You can't. you need to read your manual, locate the cmos reset jumper, and open the case. There is no such thing as bios reset software as it's at the hardware level that bios operates.

Not deteck hdd & cdrom


Power down you're system and remove the power cable from the PS.
Open you're case. First clear the cmos jumper. See bottom of page 14 in manual. The GA-8VM533M-RZ motherboard was made Jan-1-2004. It is very likely that the cmos battery needs to be replaced. Average life span is 5 years or less. Pull the cmos battery and check its voltage with a voltmeter, it should read no less than 2.7volts DC.
I'm guessing it’s the bios that’s not seeing the CD-ROM drive and the hdd? Suggest you check both the data cables and their power cables.
Since the GA-8VM533M-RZ motherboard only supports ATA IDE hdd's, check the drives jumper. (It should be jumpered as a Master) and so should the jumper on the back of the cd-rom drive. See the link provided; http://www.easeus.com/resource/install-ide-hard-drive.htm
The link above helps but you're hdd may be different. See the sticker on
you're hdd for the correct jumper setting.
If you are using a single data cable to connect both cd-rom and hdd to the motherboard don't. Use an 80-pin data cable for the hard disk drive. You can use a 40-pin data cable for the cd-rom but if you have a spare
80-pin data cable connect the cd-rom drive to it.
Connect the hdd to IDE1 and connect the cd-rom to IDE2. See motherboard layout in the manual page 5. Need the manual? Download it from Gigabyte; http://www.giga-byte.com/Products/Motherboard/Products_Spec.aspx?ProductID=1766
To view the manual you will need to download and install Adobe reader;
http://www.adobe.com/products/reader/
Re-connect the power cable to the PS. You can leave the case opened for now. Power on the system and press the Delete key every 2 seconds until the bios menu opens. (Make sure the time and date are set current). See page 19. Than turn to page 23. Make the settings as follows;
First Boot Device [Floppy] - (if one is connected)
Second Boot Device [CD-ROM
Third Boot device [HHD-0]
Password Check [Not needed]

CPU Hyper-Threading [Enabled]
Check all settings while in the bios, save and exit. The system will auto re-boot. If after replacing the bios battery (If needed), and the bios still
does not see either drive than the problem is either the bios or the motherboard's controller. The bios can be flashed but the MB controller can not be repaired.

Cheers'
Mike

Dell D505 BIOS Reset


Generally, all you need to do is get on to Dell Support and get in a chat with one of their people and tell them that you are locked out by a BIOS password, and needed to get around it. After they verify that you are the owner of the laptop, they should give you a password that gets you through it.

PATA Harddisk connection


Hi Murtazasoni, if you have the manual for K8V-MX motherboard you shouldn't have any troubles. You can download it from this link, Win XP; http://support.asus.com/download/download.aspx?modelname=K8V-MX&SLanguage=en-us
The IDE data ribbon only connects to the PATA drive & motherboard in one direction. Please see the top of page 1-22 for instructions. Most data ribbons for IDE drives have three connectors. The connector farthest from the other two connectors (Two connectors very close to each other), is plugged directly to the motherboard as shown & explained on the top of page 1-22.
If you are only connecting 1 PATA drive to the data ribbon, connect it to the last connector on the ribbon, leaving the next connector for another PATA drive.
Setting the jumper on a PATA drive. Every hard disk drive has a large white sticker on it. This sticker includes information about the drive. Things like the model number of the drive. There is also information regarding how the drive is to be set. Example: if the drive is to be the only drive in the system its jumper should be set to (Master drive only). If there is another PATA drive in the system connected to the same ribbon cable than change the jumper on the drive to, (Master with a Slave). The second PATA drive's jumper must be set to, (Slave). Connect the power cable to the PATA drive ['s]. Re-check all connectors (internally) before closing the case. Boot the system & press the Delete key on the keyboard every two seconds until the main bios menu opens. Open your manual to the top of page 2-7. Here you'll learn how to move about while in the bios. At the main menu you should see your PATA drive. Listed to the right of Primary IDE Master you should see the model number of the PATA drive listed. If not than the drive was not connected correctly. Shut down the system. Unplug the power cord from the system, open the case & re-check the data ribbon for correct orientation, solid insertion & solid insertion of power cable to drive. Connect the power cord to the system & boot to the bios again. Once the drive is listed go to the title Boot, section 2.6, page 2-27 & follow the instruction through to page 2-28.
Open your CD-ROM drive & load your windows CD, close the CD drawl.
Save bios changes & exit. The system will auto restart.
The system should start loading windows if you set the boot device correctly as shown in the manual.
If you find this too difficult to follow, suggest you ask a friend with more PC knowledge for assistance.

Good luck!
Mike

PASSWORD PROBLEMS


Hi, To access or enter motherboard BIOS settings, on powerup either F2 or Del. If you just want to remove the password in your Dell Optiplex > The BIOS password may be cleared by removing the password jumper (PSWD) on the motherboard. This will also clear all CMOS settings: Open your casing, on your motherboard. find the CMOS password reset jumper (3-pin) on the motherboard; Remove the jumper from pins 1 and 2 and put it on pins 2 and 3 for about 5 seconds. Replace back the jumper on pins 1 and 2. Hope this be of help/idea. Good luck and kind regards.
