A POST error code of 6xx indicates an issue with which device?

A POST (Power-On Self-Test) error code in the 6xx range typically indicates a problem related to the floppy drive. During the POST process, the computer performs diagnostics on various hardware components, including drives. If there is an issue detected with a floppy drive, such as failure to initialize or communication errors, the POST will generate a specific error code to signal this problem.

Floppy drives, while not as common today, were an essential part of early computing and the POST codes associated with them often helped users troubleshoot issues with these devices. Understanding this association with floppy drives is critical for recognizing the functionality of older hardware and how to diagnose it appropriately.

In contrast, error codes for keyboards, hard drives, and video adapters fall under different POST code ranges, emphasizing the need for familiarity with specific codes related to various components of a computer system.
