Bios Ripped, useful Tips on BIOS
Basic BIOS countersign able - works 9.9 times out of ten
This is a countersign drudge but it clears the BIOS such that the abutting time you alpha the PC, the CMOS does not ask for any password. Now if you are able to accompany the DOS alert up, again you will be able to change the BIOS ambience to the default. To bright the CMOS do the following:
Get DOS alert and type:
DEBUG hit enter
-o 70 2e hit enter
-o 71 ff hit enter
-q hit enter
exit hit enter
Restart the computer. It works on best versions of the AWARD BIOS.
Accessing advice on the adamantine disk
When you about-face on the host machine, admission the CMOS bureaucracy card (usually you accept to columnist F2, or DEL, or CTRL+ALT+S during the cossack sequence) and go to STANDARD CMOS SETUP, and set the approach to which you accept put the adamantine deejay as TYPE=Auto, MODE=AUTO, again SAVE & EXIT SETUP. Now you accept admission to the adamantine disk.
Standard BIOS backdoor passwords
The first, beneath invasive, attack to bypass a BIOS countersign is to try on of these accepted 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, %????? ?p??????%, %?????? ?p??????%
AMI BIOS
AMI, A.M.I., AMI SW, AMI_SW, BIOS, PASSWORD, HEWITT RAND, Oder
Other passwords you may try (for AMI/AWARD or added BIOSes)
LKWPETER, lkwpeter, BIOSTAR, biostar, BIOSSTAR, biosstar, ALFAROME, Syxz, Wodj
Note that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards (like Italian & German ones), so -- for archetype -- you should blazon AWARD?SW back application those keyboards. Also bethink that passwords are Case Sensitive. The aftermost two passwords in the AWARD BIOS account are in Russian.
Flashing BIOS via software
If you accept admission to the computer back it's angry on, you could try one of those programs that abolish the countersign from the BIOS, by abandoning its memory.
However, it ability appear you don't accept one of those programs back you accept admission to the computer, so you'd more good apprentice how to do manually what they do. You can displace the BIOS to its absence ethics application the MS-DOS apparatus DEBUG (type DEBUG at the command prompt. You'd more good do it in authentic MS-DOS mode, not from a MS-DOS carapace window in Windows). Once you are in the alter ambiance admission the afterward 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 assignment on all AT motherboards
(XT motherboards don't accept CMOS)
O 70 2E
O 71 FF
Q
Note that the aboriginal letter is a "O" not the cardinal "0". The numbers which chase are two bytes in hex format.
Flashing BIOS via hardware
If you can't admission the computer back it's on, and the accepted backdoor passwords didn't work, you'll accept to beam the BIOS via hardware. Please apprehend the important addendum at the end of this area afore to try any of these methods.
Using the jumpers
The approved way to beam the BIOS via accouterments is to plug, unplug, or about-face a jumper on the motherboard (for "switching a jumper" I beggarly that you acquisition a jumper that joins the axial pin and a ancillary pin of a accumulation of three pins, you should again unplug the jumper and again bung it to the axial pin and to the pin on the adverse side, so if the jumper is commonly on position 1-2, you accept to put it on position 2-3, or carnality versa). This jumper is not consistently amid abreast to the BIOS, but could be anywhere on the motherboard.
