Short for Advanced Configuration & Power Interface, ACPI defines a flexible and abstract hardware interface. It provides a standard way to integrate power management features throughout a PC system, including the hardware, operating system and application software. ACPI allows a computer to turn on peripherals such as CD-ROMs, network cards, hard drives, and printers, and other ACPI compatible products. With this technology, peripherals can also activate the PC. For example, inserting a tape into a VCR could turn on a PC that would activate a large-screen television and high-fidelity sound system.
If you see a red or blue screen with an ACPI error code in Windows 98, you may have a hardware or software issue. The red screen indicates that an ACPI issue with hardware or the computer BIOS, we recommend making sure you have the latest hardware drivers and BIOS updates. The blue screen indicates a software ACPI or another hidden problem, make sure you have all the latest software patches for your programs and operating system.
