Tip 1: Find Commonalities.

People like people who are like them. And people believe and trust people they like. Try to discover attitudes, likes, dislikes, family backgrounds, experiences, personality virtues or quirks, careers, goals, or values that you have in common with others; then emphasize those commonalities. People reason that if you’re like them in some ways, you’re probably like them in other ways. Therefore, they begin to transfer trust as friend to friend.

Tip 2: Show Concern and Compassion.

People tend to trust people who show concern for them. When they bleed, they want to know others bleed with them. Even companies have to show concern over self-interest in times of crisis. During the Pepsi needle syringe-tampering reports, you may recall the criticism some expressed in the company’s handling of that crisis. When the public asked about the possibility of recalls, Pepsi officials embraced logic: the cans were bottled at different plants in different parts of the country; there was no logical patterns for the alleged tampering incidents. No recalls: logical decisions. But Pepsi received criticism not for what they said, but for what they didn’t say. The absence of what some believed to be concern about public safety. The same is true on an individual level. People have to feel your concern before they hear your words.

Tip 3: Demonstrate Cooperation with Good Intentions.

To be credible, you must demonstrate that you are acting in good faith to the best of your knowledge and ability. People must believe that you want to cooperate to help them achieve their personal and career goals. People will forgive you for poor judgment, but rarely for poor intentions.

Tip 4: Be Consistent.

We communicate by actions as well as words. We communicate by what we say and what we don’t say; by which policies we enforce and which policies we don’t enforce; by what we allow work time for and what we don’t allow work time for; by what we fund and what we don’t fund; by behavior we reward and behavior we punish; by what we do and what we criticize others for doing; by what we ask for and what we’re willing to give in return. To be credible, our words have to match our policies, performance, and plans.

Tip 5: Demonstrate Competence.

People flock to experts, star performers, wise decision makers, and winners. People don’t intentionally invest their money in poorly performing stock; neither do they want to invest trust in people they doubt can achieve what they claim. To be led, either by words or actions, followers need to have faith in your competence to perform. They want to know you can win the game. They want to know you can finish the project successfully. They want to know you can turn the company around.

So how do leaders inspire confidence in their abilities while seeming modest and likable as people? They as leaders have to acknowledge accomplishments but avoid arrogance. Difficult, but not impossible. How? The attitude behind the talk turns the tables.

Tip 6: Be Correct.

Few people set out to be incorrect; it’s just that when they have missing information, they make assumptions or reason wrongly. Instead of informing, they misinform unintentionally. Whether or not people routinely ask for the source of your information or conclusions, be ready to provide it. If they ask for sources, rather than be offended, welcome such testing questions as credibility checkers.

Why would people want sources for relatively insignificant information? Because we test validity on all important matters by considering the source. How do we test the source of important information? By checking the credibility of all information coming from that same source. Credibility is circular. Credibility in the insignificant breeds credibility for the significant. Once you’re caught in an error, credibility creeps back ever so slowly.

Tip 7: Be Complete.

Are you telling all you know? Recognize the difference between lies, half-truths, omissions, and cover-ups. True, but incomplete, statements can lead to false conclusions; literal truths, when offered without complete explanations, can lead to literal lies. Knowing smiles accompanied by long silences can elicit wrong conclusions. Lying happens in numerous ways. Intentions stand center stage here. Ultimately, questionable intentions cast doubt about character.

Tip 8: Be Current.

Give up outdated data, opinions, and stereotypes. With information overload, data more than two or three years old can’t support your decisions. Correct, but outdated, statistics soon become incorrect. Recollect.

Tip 9: Be Clear.

Sometimes the better we understand something the worse job we do of explaining it; our familiarity makes us careless in describing it. It’s difficult to remember when we didn’t know something that has become second nature. Ambiguity creeps in when we least expect it. Meaning depends on context, tone, timing, personal experience, and reference points.

Back in the days when copier equipment was said to “burn copies,” an Army colonel hand-carried an important document to his new assistant and asked her to burn a copy. When the paper did not resurface on his desk in a few days, he discovered that the assistant had recently transferred from a high-security division. She had had the document incinerated. Are you clear? Are you sure? The best test of clarity is the result you see.

Tip 10: Avoid Exaggeration.

Was the score 50 to zip or 30 to 10? Did you have to wait half an hour or half a minute? Did the caller slam down the phone or hesitate to talk? Did the supplier raise the prices on your raw materials 10 percent or 2 percent? Exaggeration makes great humor but destroys credibility.

Tip 11: Evaluate Criticism and Objections.

If you reject or refute criticisms and objections out of hand, without hearing them out and giving yourself time to consider them fully, you lose credibility. People identify you as a reactor rather than a reflective, credible thinker. The more thorough your consideration of contradictory information the more credible your final opinion or decision.

Tip 12: Keep Confidences.

When people know you share personal, confidential matters about others with them, they’ll fear you’ll do the same thing where they’re concerned. Keeping confidences when “nobody would know you told” speaks volumes about character. Those who observe your discretion in deciding to keep quiet about hurtful or personal information involving others bridge to other favorable conclusions about your credibility in times of stress.

Tip 13: Avoid Lying “Offstage.”

When you lie to a third person in front of a second person and that second person knows you’re lying—for whatever reason—you lose credibility with the second person. Once observers have recognized your willingness to lie to others, they will doubt your truth-telling to them in a tight spot.

Tip 14: Be Sincere and Genuine.

Sincerity is easy to fake and hard to make. That is, people who pretend to be sincere can pitch an earnest plea, look at you with pleading eyes and straight face, and promise plums that dance in your head. But genuineness comes from character and is therefore harder to make. You either are or you aren’t. What you experience is what you share. What you value is what you give. What you say is what you believe.

Tip 15: Make Your Appearance Work for You.

Picture yourself lying on the operating table in a hospital emergency room. A guy in sweats and Nikes jogs toward your bedside and says, “I’m Kelly, the brain surgeon. I’ll be ready to operate in a moment. Just let me give you this shot first.” Would you have a few second thoughts? Appearance counts. Physical appearance, dress, grooming, posture, presence, and poise either underscore credibility or damage it. Look at the part you want to play so others will believe and applaud your lines.

Basic BIOS password crack - works 9.9 times out of ten
This is a password hack but it clears de BIOS such that de next time you start de PC, de CMOS does not ask for any password. Now if you are able to brin’ de DOS prompt up, den you will be able to change de BIOS settin’ to de default. To clear de CMOS do de followin’:
Get DOS prompt and type:

DEBUG hit enter
-o 70 2e hit enter
-o 71 ff hit enter
-q hit enter
exit hit enter

Restart de computer. It works on most versions of de AWARD BIOS.

Accessin’ information on de hard disk
When you turn on de host machine, enter de CMOS setup menu (usually you have to press F2, or DEL, or CTRL+ALT+S durin’ de boot sequence) and go to STANDARD CMOS SETUP, and set de channel to which you have put de hard disk as TYPE=Auto, MODE=AUTO, den SAVE & EXIT SETUP. Now you have access to de hard disk.

Standard BIOS backdoor passwords
The first, less invasive, attempt to bypass a BIOS password is to try on of dese standard manufacturer’s backdoor passwords:

AWARD BIOS
AWARD SW, AWARD_SW, Award SW, AWARD PW, _award, awkward, J64, j256, j262, j332, j322, 01322222, 589589, 589721, 595595, 598598, HLT, SER, SKY_FOX, aLLy, aLLY, Condo, CONCAT, TTPTHA, aPAf, HLT, KDD, ZBAAACA, ZAAADA, ZJAAADC, djonet

AMI BIOS
AMI, A.M.I., AMI SW, AMI_SW, BIOS, PASSWORD, HEWITT RAND, Oder

Oder passwords you may try (for AMI/AWARD or oder BIOSes)
LKWPETER, lkwpeter, BIOSTAR, biostar, BIOSSTAR, biosstar, ALFAROME, Syxz, Wodj

Note that de key associated to “_” in de US keyboard corresponds to “?” in some European keyboards (such as Italian and German ones), so — for example — you should type AWARD_SW when usin’ those keyboards. Also remember that passwords are Case Sensitive. The last two passwords in de AWARD BIOS list are in Russian.

Flashin’ BIOS via software
If you have access to de computer when it’s turned on, you could try one of those programs that remove de password from de BIOS, by invalidatin’ its memory. However, it might happen you don’t have one of those programs when you have access to de computer, so you’d better learn how to do manually what dey do. You can reset de BIOS to its default values usin’ de MS-DOS tool DEBUG (type DEBUG at de command prompt. You’d better do it in pure MS-DOS mode, not from a MS-DOS shell window in Windows). Once you are in de debug environment enter de followin’ commands:

AMI/AWARD BIOS
O 70 17
O 71 17
Q

PHOENIX BIOS
O 70 FF
O 71 17
Q

GENERIC
Invalidates CMOS RAM.
Should work on all AT moderboards
(XT moderboards don’t have CMOS)
O 70 2E
O 71 FF
Q
Note that de first letter is a “O” not de number “0″. The numbers which follow are two bytes in hex format.

Flashin’ BIOS via hardware
If you can’t access de computer when it’s on, and de standard backdoor passwords didn’t work, you’ll have to flash de BIOS via hardware. Please read de important notes at de end of this section before to try any of dese methods.

Usin’ de jumpers
The canonical way to flash de BIOS via hardware is to plug, unplug, or switch a jumper on de moderboard (for “switchin’ a jumper” I mean that you find a jumper that joins de central pin and a side pin of a group of three pins, you should den unplug de jumper and den plug it to de central pin and to de pin on de opposite side, so if de jumper is normally on position 1-2, you have to put it on position 2-3, or vice versa). This jumper is not always located near to de BIOS, but could be anywhere on de moderboard. To find de correct jumper you should read de moderboard’s manual. Once you’ve located de correct jumper, switch it (or plug or unplug it, dependin’ from what de manual says) while de computer is turned OFF. Wait a couple of seconds den put de jumper back to its original position. In some moderboards it may happen that de computer will automatically turn itself on, after flashin’ de BIOS. In this case, turn it off, and put de jumper back to its original position, den turn it on again. Oder moderboards require you turn de computer on for a few seconds to flash de BIOS. If you don’t have de moderboard’s manual, you’ll have to “brute force” it… tryin’ out all de jumpers. In this case, try first de isolated ones (not in a group), de ones near to de BIOS, and de ones you can switch (as I explained before). If all them fail, try all de oders. However, you must modify de status of only one jumper per attempt, oderwise you could damage de moderboard (since you don’t know what de jumper you modified is actually meant for). If de password request screen still appear, try anoder one. If after flashin’ de BIOS, de computer won’t boot when you turn it on, turn it off, and wait some seconds before to retry.

Removin’ de battery
If you can’t find de jumper to flash de BIOS or if such jumper doesn’t exist, you can remove de battery that keeps de BIOS memory alive. It’s a button-size battery somewhere on de moderboard (on elder computers de battery could be a small, typically blue, cylinder soldered to de moderboard, but usually has a jumper on its side to disconnect it, oderwise you’ll have to unsolder it and den solder it back). Take it away for 15-30 minutes or more, den put it back and de data contained into de BIOS memory should be volatilized. I’d suggest you to remove it for about one hour to be sure, because if you put it back when de data aren’t erased yet you’ll have to wait more time, as you’ve never removed it. If at first it doesn’t work, try to remove de battery overnight.

Important note: in laptop and notebooks you don’t have to remove de computer’s power batteries (which would be useless), but you should open your computer and remove de CMOS battery from de moderboard.

Short-circuitin’ de chip
Anoder way to clear de CMOS RAM is to reset it by short circuitin’ two pins of de BIOS chip for a few seconds. You can do that with a small piece of electric wire or with a bent paper clip. Always make sure that de computer is turned OFF before to try this operation.

Here is a list of EPROM chips that are commonly used in de BIOS industry. You may find similar chips with different names if dey are compatible chips made by anoder brand. If you find de BIOS chip you are workin’ on matches with one of de followin’ you can try to short-circuit de appropriate pins. Be careful, because this operation may damage de chip.

CHIPS P82C206 (square)
Short togeder pins 12 and 32 (de first and de last pins on de bottom edge of de chip) or pins 74 and 75 (de two pins on de upper left corner).

Dallas DS1287, DS1287A
Benchmarq bp3287MT, bq3287AMT
The Dallas DS1287, DS1287A and Benchmarq bp3287MT, bq3287AMT chips have a built-in battery. This battery should last up to ten years. Any moderboard usin’ dese chips should not have an additional battery (this means you can’t flash de BIOS by removin’ a battery). When de battery fails, de RTC chip would be replaced. CMOS RAM can be cleared on de 1287A and 3287AMT chips by shortin’ pins 12 and 21. The 1287 (and 3287MT) differ from de 1287A in that de CMOS RAM can’t be cleared. If dere is a problem such as a forgotten password, de chip must be replaced. (In this case it is recommended to replace de 1287 with a 1287A). Also de Dallas 12887 and 12887A are similar but contain twice as much CMOS RAM storage.

Replacin’ de chip
If nothin’ works, you could replace de existin’ BIOS chip with a new one you can buy from your specialized electronic shop or your computer supplier. It’s a quick operation if de chip is inserted on a base and not soldered to de moderboard, oderwise you’ll have to unsolder it and den put de new one. In this case would be more convenient to solder a base on which you’ll den plug de new chip, in de eventuality that you’ll have to change it again. If you can’t find de BIOS chip specifically made for your moderboard, you should buy one of de same type (probably one of de ones shown above) and look in your moderboard manufacturer’s website to see if dere’s de BIOS image to download. Then you should copy that image on de chip you bought with an EPROM programmer.

Important
Wheder is de method you use, when you flash de BIOS not only de password, but also all de oder configuration data will be reset to de factory defaults, so when you are bootin’ for de first time after a BIOS flash, you should enter de CMOS configuration menu (as explained before) and fix up some thin’s.
Also, when you boot Windows, it may happen that it finds some new device, because of de new configuration of de BIOS, in this case you’ll probably need de Windows installation CD because Windows may ask you for some external files. If Windows doesn’t see de CD-ROM try to eject and re-insert de CD-ROM again. If Windows can’t find de CD-ROM drive and you set it properly from de BIOS config, just reboot with de reset key, and in de next run Windows should find it. However most files needed by de system while installin’ new hardware could also be found in C:WINDOWS, C:WINDOWSSYSTEM, or C:WINDOWSINF .

Key Disk for Toshiba laptops
Some Toshiba notebooks allow to bypass BIOS by insertin’ a “key-disk” in de floppy disk drive while bootin’. To create a Toshiba Keydisk, take a 720Kb or 1.44Mb floppy disk, format it (if it’s not formatted yet), den use a hex editor such as Hex Workshop (***.bpsoft.com/downloads/index.html) to change de first five bytes of de second sector (de one after de boot sector) and set them to 4B 45 59 00 00 (note that de first three bytes are de ASCII for “KEY” followed by two zeroes). Once you have created de key disk put it into de notebook’s drive and turn it on, den push de reset button and when asked for password, press Enter. You will be asked to Set Password again. Press Y and Enter. You’ll enter de BIOS configuration where you can set a new password.

Key protected cases
A final note about those old computers (up to 486 and early Pentiums) protected with a key that prevented de use of de mouse and de keyboard or de power button. All you have to do with them is to follow de wires connected to de key hole, locate de jumper to which dey are connected and unplug it.

How to Bypass BIOS Passwords

BIOS passwords can add an extra layer of security for desktop and laptop computers. They are used to eider prevent a user from chan’in’ de BIOS settin’s or to prevent de PC from bootin’ without a password. Unfortunately, BIOS passwords can also be a liability if a user forgets deir password, or changes de password to intentionally lock out de corporate IT department. Sendin’ de unit back to de manufacturer to have de BIOS reset can be expensive and is usually not covered in de warranty. Never fear, all is not lost. There are a few known backdoors and oder tricks of de trade that can be used to bypass or reset de BIOS

DISCLAIMER
This article is intended for IT Professionals and systems administrators with experience servicin’ computer hardware. It is not intended for home users, hackers, or computer thieves attemptin’ to crack de password on a stolen PC. Please do not attempt any of dese procedures if you are unfamiliar with computer hardware, and please use this information responsibly. LabMice.net is not responsible for de use or misuse of this material, includin’ loss of data, damage to hardware, or personal injury.

Before attemptin’ to bypass de BIOS password on a computer, please take a minute to contact de hardware manufacturer support staff directly and ask for deir recommended methods of bypassin’ de BIOS security. In de event de manufacturer cannot (or will not) help you, dere are a number of methods that can be used to bypass or reset de BIOS password yourself. They include:

Usin’ a manufacturers backdoor password to access de BIOS

Use password crackin’ software

Reset de CMOS usin’ de jumpers or solder beads.

Removin’ de CMOS battery for at least 10 minutes

Overloadin’ de keyboard buffer

Usin’ a professional service

Please remember that most BIOS passwords do not protect de hard drive, so if you need to recover de data, simply remove de hard drive and install it in an identical system, or configure it as a slave drive in an existin’ system. The exception to this are laptops, especially IBM Thinkpads, which silently lock de hard drive if de supervisor password is enabled. If de supervisor password is reset without resettin’ de and hard drive as well, you will be unable to access de data on de drive.

——————————————————————————–

Backdoor passwords

Many BIOS manufacturers have provided backdoor passwords that can be used to access de BIOS setup in de event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that de key associated to “_” in de US keyboard corresponds to “?” in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.

WARNING: Some BIOS configurations will lock you out of de system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for de BIOS settin’ before you begin typin’ in passwords

Usin’ de Moderboard “Clear CMOS” Jumper or Dipswitch settin’s

Many moderboards feature a set of jumpers or dipswitches that will clear de CMOS and wipe all of de custom settin’s includin’ BIOS passwords. The locations of dese jumpers / dipswitches will vary dependin’ on de moderboard manufacturer and ideally you should always refer to de moderboard or computer manufacturers documentation. If de documentation is unavailable, de jumpers/dipswitches can sometimes be found alon’ de edge of de moderboard, next to de CMOS battery, or near de processor. Some manufacturers may label de jumper / dipswitch CLEAR - CLEAR CMOS - CLR - CLRPWD - PASSWD - PASSWORD - PWD. On laptop computers, de dipswitches are usually found under de keyboard or within a compartment at de bottom of de laptop.
Please remember to unplug your PC and use a groundin’ strip before reachin’ into your PC and touchin’ de moderboard. Once you locate and rest de jumper switches, turn de computer on and check if de password has been cleared. If it has, turn de computer off and return de jumpers or dipswitches to its original position.

Removin’ de CMOS Battery

The CMOS settin’s on most systems are buffered by a small battery that is attached to de moderboard. (It looks like a small watch battery). If you unplug de PC and remove de battery for 10-15 minutes, de CMOS may reset itself and de password should be blank. (Alon’ with any oder machine specific settin’s, so be sure you are familiar with manually reconfigurin’ de BIOS settin’s before you do this.) Some manufacturers backup de power to de CMOS chipset by usin’ a capacitor, so if your first attempt fails, leave de battery out (with de system unplugged) for at least 24 hours. Some batteries are actually soldered onto de moderboard makin’ this task more difficult. Unsolderin’ de battery incorrectly may damage your moderboard and oder components, so please don’t attempt this if you are inexperienced. Anoder option may be to remove de CMOS chip from de moderboard for a period of time.

Note: Removin’ de battery to reset de CMOS will not work for all PC’s, and almost all of de newer laptops store deir BIOS passwords in a manner which does not require continuous power, so removin’ de CMOS battery may not work at all. IBM Thinkpad laptops lock de hard drive as well as de BIOS when de supervisor password is set. If you reset de BIOS password, but cannot reset de hard drive password, you may not be able to access de drive and it will remain locked, even if you place it in a new laptop. IBM Thinkpads have special jumper switches on de moderboard, and dese should be used to reset de system.

Overloadin’ de KeyBoard Buffer

On some older computer systems, you can force de CMOS to enter its setup screen on boot by overloadin’ de keyboard buffer. This can be done by bootin’ with de keyboard or mouse unattached to de systems, or on some systems by hittin’ de ESC key over 100 times in rapid succession.

Jumpin’ de Solder Beads on de CMOS

It is also possible to reset de CMOS by connectin’ or “jumpin’” specific solder beads on de chipset. There are too many chipsets to do a breakdown of which points to jump on individual chipsets, and de location of dese solder beads can vary by manufacturer, so please check your computer and moderboard documentation for details. This technique is not recommended for de inexperienced and should be only be used as a “last ditch” effort.

Usin’ a professional service

If de manufacturer of de laptop or desktop PC can’t or won’t reset de BIOS password, you still have de option of usin’ a professional service. Password Crackers, Inc., offers a variety of services for desktop and laptop computers for between $100 and $400. For most of dese services, you’ll need to provide some type of legitimate proof of ownership. This may be difficult if you’ve acquired de computer second hand or from an online auction.
