You can get the cmos password finding program cmospwd,here (www.pcworld.com) If that doesnt work, then there is a nice wicked program called Killcmos, which will wipe it clean. Your AV will think it is a virus though because of the type of code written into it. It isnt :) |

| 238681 | 2004-05-23 10:37:00 | You are lucky the Dallas clock is plugged in. Many were soldered in and when the battery expires thats it ..kaput! Those batteries are supposed to have a life of up to 10 years ....so they say.... :) To replace may cost about $40-60. |

| 238682 | 2004-05-23 10:41:00 | i would use the cmos wipe program, but there is a problem. you see while the password is enabled the system wont actually get past the post, so no booting from harddive, floppy or anything it seems.... also, could you or someone please explain what the dallas thing actually is and does? |

| 238683 | 2004-05-23 10:49:00 | From an article on Dallas CMOS chips: Someone put a password in my Dallas Semiconductor DS12887 chip. Is there any way to remove it? Unfortunately, no. Dallas Semiconductor products without an "A" at the end of the model number can only be reset using a password. Our recommendation is to password protect all systems using this type of device with the same password and keep the password under lock and key in one or more places. Dallas Semiconductor devices that do have an "A" at the end of their model number can be completely erased even if they are password protected. This is usually accomplished with a jumper on the system board. It is also possible to use a device with an "A" at the end of the model number in systems that don't have this feature. To eliminate tampering on those systems that do not have a RAM clear jumper, we recommend that users password protect the device and tape a copy of the password INSIDE the computer case. |

| 238684 | 2004-05-23 10:57:00 | Looks like GF has put his finger on the problem. A Dallas 'clock' is a cmos chip and real time clock with internal battery all rolled into one, rather than 3 separate items as is more usual. |

| 238685 | 2004-05-23 10:59:00 | Well those dallas people are mighty clever aint they? my chip is a DS1387 - no A attached. |

| 238686 | 2004-05-23 11:13:00 | www.maxim-ic.com Confusing. It suggests only those with an A can be reset in this link. |

| 238688 | 2004-05-23 11:23:00 | There are some CMOS "backdoor" passwords, depending on CMOS type. Have a look here (www.elfqrin.com). | Pheonix (280) | ||
