Acpi — Genuineintel---intel64-family-6-model-58

Sample answer (concise, but must compile with iasl). Partial credit for syntactically consistent fragments.

While it looks like a chaotic mix of punctuation and numbers, this string is a precise, standardized shorthand that your operating system uses to communicate with your computer’s motherboard and processor.

This indicates that the identifier is being reported by the system's firmware (BIOS/UEFI) to the Operating System kernel. It is the standard interface used for power management and hardware discovery. acpi genuineintel---intel64-family-6-model-58

Structure

If you have ever dug deep into your Windows Device Manager or system logs and found the string ACPI\GenuineIntel_-_Intel64_Family_6_Model_58 Sample answer (concise, but must compile with iasl)

The problem is that Intel CPUs evolve rapidly, and each microarchitecture handles power transitions slightly differently. ACPI tables (the DSDT/SSDT) are written by the motherboard vendor (BIOS/UEFI) and are often generic. The Linux kernel, upon boot, reads the ACPI tables, then checks the actual CPUID. When it sees family=6, model=58 , it knows:

This is the specific identifier for the microarchitecture. In the context of Family 6, Model 58 (hexadecimal 3A) refers to the Ivy Bridge architecture. This indicates that the identifier is being reported

: Confirms the microprocessor supports the x86-64 long-mode instruction set. This allows the execution of 64-bit applications and addressing allocations beyond 4 Gigabytes of physical memory. 3. Family 6

Without the proper Intel Chipset Device Software, Windows may not recognize the specific power management features of the Ivy Bridge architecture.

To understand this specific string, we first need to understand ACPI. Introduced in the late 1990s, ACPI is an open standard that allows an operating system to communicate with and manage the power usage of its hardware. Before ACPI, power management was largely the BIOS's responsibility. ACPI shifted that control to the OS, enabling features like putting individual devices to sleep when not in use or waking the system on a timer.

Why does this string appear? It is often seen in system logs, Device Manager properties, or Linux dmesg outputs.
