The is a driver for a specific family of Intel I/O Controllers that manage the connection between the motherboard's storage controller (ATA, SATA) and storage devices like hard drives, CD/DVD drives, or solid-state drives (SSDs). The Intel 82801EB chipset is commonly found in older Intel motherboards, typically from the early 2000s.

The Ultra ATA designation refers to the ATA (Advanced Technology Attachment) interface, which was used for connecting storage devices before the introduction of SATA (Serial ATA) technology. Ultra ATA was a faster version of the older ATA standard and was commonly used for hard drives and optical drives in the pre-SATA era.
