Please read the Readme. The bios in this system is not fully ACPI compliant. Please contact your system vendor for an updated bios. If you are unable to obtain an updated bios or the latest bios supplied by your vendor is not ACPI compliant, you can turn off ACPI mode during text mode setup.
To do this, simply press the F7 key when you are prompted to install storage drivers. The system will not notify you windows 7 error code 0x00000a5 free download the F7 key was pressed--it will windows 7 error code 0x00000a5 free download disable ACPI and allow you to continue your installation. The parameters Parameter1Parameter2Parameter3and Parameter4 vary from computer to computer.
There is nothing that you can fix at the level of the operating system. This Stop message can occur at other times. For example, you could receive this Stop error after you install Windows XP and later make a hardware change, such as adding a device. Windows 98 may allow workarounds that Windows XP cannot use because of its more stringent requirements for system stability. The following information lists possible causes of the Stop 0xA5 error. To identify the cause of this Stop error, note Parameter1 and compare it to the numbers listed in the following paragraphs, to get a general idea of the problem.
The other parameters arguments are not discussed in this article. You can view these other arguments only by connecting the system to a kernel debugger.
This article provides a description of the issues that this Stop error can involve, without requiring more advanced debugging. For more information, refer to Acpidbg. SCI is a special interrupt type that provides a more efficient way to deal with problems that are normally handled by system management interrupts SMI.
This error occurs if the BIOS lacks a pointer to the list, or if the list is empty, or if the list contains errors or conflicts. Other arguments for this error reference the ACPI object that was being run and the name of the control method. One greatly simplified explanation which might not be completely accurate is that the system cannot find a way to get to the ACPI tables that define the Plug and Play and Power Management capabilities of the system.
For example, if you have an add-in adapter in a docking station and you attempt to eject the laptop computer, ACPI references this namespace to determine whether the dependent adapter in the docking station supports the ejection.
This can be because it is not properly defined or because there are duplicate services defined. Technically, these objects are optional, but they absolutely must be present to describe any device that is enumerated by an ACPI driver. These are anything other than a "device.
Resource descriptors describe the system resources that the computer is using, can use, or wants to use. Each descriptor entry has a predefined size, which must match the data returned. This error occurs if Power Resource maps to a nonexistent system-wide resource. You can use windows 7 error code 0x00000a5 free download kernel debugger to view the specifics of this error, including the system power state that windows 7 error code 0x00000a5 free download causing the problem.
There are many reasons for this, including:. ACPI is a hierarchical arrangement of tables, each one building upon the next to define the complete capabilities of the system and of every device in the system.
ACPI starts by looking for the Root System Description table, windows 7 error code 0x00000a5 free download points to the next table, which points to the next table, and so on. Usually, the 0x error occurs because these tables are damaged or missing.
You can view the error through a kernel debugger to see what the exact object is. This error is usually due to a damaged interrupt routing table. To prevent ambiguity, the device number must be specified in the table but the function number must not. To this end, the function field must be set to all F's. This error occurs when a function number is not all F's. This error occurs if ACPI cannot disable a link node. Need more help? Expand your skills. Get new features first.
