Ayant eu un retour du support ABIT, j’en fait profiter tout le monde :
[code]If your system is beeping like siren alarm.
There are two devices can cause the alarm. One is BIOS and the other one is AbitEQ or similar hardware monitor program i.e.Winbond Hardware DOC.
If the alarm happens before the Windows, then the alarm is caused by the BIOS. You should check BIOS/PC health status or uGuru setup for the readings and settings, usually relative to the CPU temperature, CPU fan speed or PWM temperature.
In some case, the alarm went off when the system is power on. Because CPU is cool, therefore the CPU fan is slow. But before Windows even completely boots up, the CPU is hot and the fan rpm increased. Then the alarm beeps disappeared.
If the alarm sounds after the Windows, then apart from the possibility of the BIOS, it could be also the hardware monitor program, i.e. Abit EQ.
If you are not able to determine which is caused the alarm, simply uninstall the hardware monitor program and see if alarm will went off.
If the system shuts down, please enter the BIOS and check the PC Health status or uGuru/Abit EQ for the monitoring. You may able to find out which item is causing the alarm and shut down. You can disable the alarm and shut down option in the BIOS. This should make the system stays long enough for a BIOS upgrade from floppy driver.
Above link has details of how to update the BIOS thru the floppy disk drive.
The AbitEQ can monitor much more item than BIOS, therefore, any abnormal reading or set up can cause the alarm.
You should double check all settings and readings, if necessary, please increase the range to include the reading that causes the alarm. This includes all of voltages, temperatures and fan speed readings.
However, there are upper and lower limits, i.e. the CPU fan so slow that lower than the lower limit. Then the alarm will went off whenever the EQ is running. You can not lower the limit to include the slow fan speed since it is already on the limit.
If you have a case fan connected to the mainboard. The easiest way to sort this problem is to connect the CPU to the case fan header and connect the case fan header to the CPU fan header. By doing so, the CPU fan detection will be the case fan speed and usually the case fan has higher rpm.
This is also an option for the water cooler system, since there is no CPU fan.
If you have PWM temperature issue, it is best to add a case fan right behind the CPU and taking the air in.
Please note that if you are using the Intel Prescott P4 CPUs, please use the Intel recommendation heatsink and fan. Prescott CPUs request mush more power than Northwood P4, therefore, generate higher temperature at the CPU and the mainboard PWM circuit. Please visit the links below for the details.
We also found that the quality of PSU will affect the temperatures as well. Please check the BIOS voltage monitoring for the voltages, in particular, the ATX+12V. The voltages should not be fluctuating too much and ATX+12V should be between +11.9V to +12.1V. Otherwise, the temperature will increase.
Please note that you can always go to www.abit.com.tw to download the latest version of Guru or EQ utility and update the to the latest BIOS.
In some cases, the Abit EQ or BIOS is misreading the temperature and this can be because the BIOS or EQ itself. Or a new model of CPU needed to be supported.
And to install this utility, you must be the administrator of the Windows.
