Where can I find BIOS for my IBM motherboard? Motherboard: IBM 830336U Тип BIOS Phoenix Версия BIOS 24KT22AUS Chipset: Intel 2560 rev 1 Northbridge Intel i845G rev. A1 Southbridge Intel 82801DB (ICH4) rev. 01 Videocontroller does not work at all after reinstall WinXP, driver is not possible to install, so I need to renew BIOS. Can you please send me the files, or give links to the bios and programm file to install it?

Desktop Machines.

In desktop machines its very simple.
Just remove the BIOS Battery from the motherboard and place it back after 1mint.

Laptop Machines.

It is some what difficult in laptop machines. Because it is not an eassy job to remove BIOS battery from the mother board. So i'm just explaining some most commen methods.
1. Using a Backdoor BIOS Password

The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.

AMI Backdoor BIOS Passwords Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
Award Backdoor BIOS Passwords One reported Award backdoor BIOS password is eight spaces. Other reported Award backdoor BIOS passwords include 01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT, CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332, J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz, TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.
Phoenix Backdoor BIOS Passwords Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.
Backdoor BIOS Passwords from Other Manufacturers Reported BIOS backdoor passwords for other manufacturers include:
Manufacturer BIOS Password VOBIS & IBM merlin Dell Dell Biostar Biostar Compaq Compaq Enox xo11nE Epox central Freetech Posterie IWill iwill Jetway spooml Packard Bell bell9 QDI QDI Siemens SKY_FOX SOYO SY_MB TMC BIGO Toshiba Toshiba Remember that what you see listed may not be the actual backdoor BIOS password, this BIOS password may simply have the same checksum as the real backdoor BIOS password. For Award BIOS, this checksum is stored at F000:EC60.

2. Resetting the BIOS Password using Software :

!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.

CmosPwd will recover the BIOS password for the following BIOS versions:

• ACER/IBM BIOS

• Phoenix 4 release 6 (User)
• Gateway Solo - Phoenix 4.0 release 6
• Toshiba
• Zenith AMI

3. Resetting the BIOS Password using Hardware :

If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.
On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.
If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.
Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it.

There are two passwords in BIOS. One is start up password, the other isBIOS setting password. If you have forgotten the start up password thatmeans you cannot open computer at all. Then the first method is theonly thing you can do. Other methods can use to clear setting password.
==①:Motherboard Battery Discharge==
The common way toreset start up password is discharge Motherboard Battery. Most of thecurrent motherboard BIOS is using the button batteries to provideelectric power.That means if there is no electricity, the informationit contains will be lost. When it’s on power again, BIOS will set backto its original state, of course, there will be no BIOS passwords. Butyou will lose your setting at the same time.
What we need to dois to power off computer, open the computer box, and then unplug thepower plug of the computer to make sure that it is no electricity atall. Then locate the white silver button battery on the motherboard.Remove the battery carefully. Perhaps 30 seconds later, put back thebattery.
After put back the computer box then power on, thesystem will prompt “CMOS Checksum Error-Defaults Loaded”. That meansCMOS errors detected during inspections, had been included in thesystem default, BIOS password cracking success!
On somemotherboards, the battery is soldered to the motherboard, making itdifficult to remove. If this is the case, you have another alternative.Somewhere on the motherboard you should find a jumper that will clearthe BIOS password. If you have the motherboard documentation, you willknow where that jumper is. If not, the jumper may be labeled on themotherboard. If you are not fortunate enough for either of these to bethe case, you may be able to guess which jumper is the correct jumper.This jumper is usually standing alone near the battery. If you cannotlocate this jumper, you might short both of the points where thebattery connects to the motherboard.
==② : Backdoor BIOS Password==
Eachmotherboard manufacturer has set a backdoor password in order tofacilitate the provision of technical support. The backdoor password isa BIOS password that works, no matter what the user sets the BIOSpassword to. These passwords are typically used for testing andmaintenance. Manufacturers typically change the backdoor BIOS passwordsfrom time to time.

==③: Software Crack==
There are a lotsoftwares to test systems or start up password, but they need to run onWindows. So it is only used to reset BIOS setting password.
!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.
CmosPwd will recover the BIOS password for the following BIOS versions:
•ACER/IBM BIOS

Ifall else fails, you might be going to lose some money for technician.But they will use these same methods, try hard by yourself.
