The BIOS information is typically found at or near the top of the POST screen for a very short time
ALR PC non / PCI =CTRL+ALT+ESC
AMD advanced micro devices=BIOS = DEL
Award BIOS = DEL
Dtk Datatech Enterprises Co. BIOS = ESC
Phoenix BIOS = CTRL+ALT+S
Phoenix BIOS = CTRL+ALT+INS
Restart your computer during the boot process you will see on the screen to press a certain key usually Delete or F2 to enter setup this will differ depending on which bios you have Press and hold that key during the boot up process to enter BIOS if you have changed any of the BIOS settings by mistake you can load failsafe or optimised defaultsusing the arrow keys you can after you make any changes in BIOS press Esc then press the F10 button save to cmos to restart CMOS is an on-board semiconductor chip powered by a CMOS battery inside computers that stores information such as the system time and date and the system hardware settings for your computer.. hope this helps
Computer POST and beep codes The computer power on self test (POST) will test your computer to make sure it can boot properly(test hardware and sys requirements), once it does the computer will then finish the boot process. Normally, if your computer passes the POST test it will beep once or possibly twice. If the computer fails the POST then it will either not beep at all or generate a beep code.
The beep code you receive can indicate what may be wrong with your computer. The beep codes vary depending on your motherboard BIOS manufacturer(AMI, Award, Phoenix). You can find what BIOS you are using by paying attention to the BIOS screen when your computer boots up. It should tell you what brand BIOS.
Every system must store the BIOS password
information somewhere. If you are able to access the machine after it has been
booted successfully, you may be able to view the BIOS password. You must know
the memory address where the BIOS password is stored, and the format in which
the BIOS password is stored. Or, you must have a program that knows these
You can write your own program to read the
BIOS password from the CMOS memory on a PC by writing
the address of the byte of CMOS memory that you wish to read in port 0×370, and
then reading the contents of port 0×371.
!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
The solution will offer many approaches to resolving a BIOSpassword you need removed.
1. Using a Backdoor BIOS password Some BIOS manufacturers implement a backdoor password. The backdoor password isa BIOS password that works regardless of what any other user has set as a BIOSpassword. Although manufacturers change these passwords with newerreleases of hardware, it's worth trying these passwords first before employingmore time-intensive methods.
AMI:Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW ,AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
AWARD: One reported Award backdoor BIOS password is eight spaces. Other reported Awardbackdoor 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, andZJAAADC.
Phoenix:Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, andPHOENIX.

2.Using Software to Reset BIOS Password
Thereare two programs that can be used to reset the BIOS password: !BIOS andCmosPwd.
!BIOSwill recover the BIOS password for most common BIOS versions, including IBM,American Megatrends Inc, Award and Phoenix. You can download it here.Click on Download DOS executable.
CmosPwd will recover the BIOS password for the following BIOSversions:
You can download CmosPwd here. Scroll down andlook for Cmos password recoverytools 5.0 (October 2007) and click the zip that contains a hyperlink.
In order to use these two programs you will need toboot into DOS from a Windows 98 disk or create a DOS boot disk that you can burnto CD or copy to a flash drive. If you don't know how to do this, thenpost back and I can post further instructions.
sounds like you lost your BIOS, you may need to find a way to get the BIOS on a bootable disc, then re flash you BIOS. the only problem is you need to know the maker of your BIOS, i have an IBM and Phoenix Technologies made my BIOS, i just downloaded a new version from the IBM website and reflashed mine, but if you get the wrong version you can destroy your motherboard.
