SATA receiver equalization margin determination/setting method and apparatus

摘要

Apparatuses, methods and storage medium associated with automatic SATA receiver equalization margin determination and setting, are disclosed. In embodiments, an apparatus may comprise a BIOS configured to determine, during POST, whether a device is attached to one of the SATA ports, and on determination that a device is attached to one of the SATA ports, further determine whether a receiver equalization margin has been set for the device. Additionally, the BIOS may be configured to perform a DTLE training to dynamically determine and set the receiver equalization margin for the device, on determination that a receiver equalization margin has not been set for the device. Other embodiments may be described and/or claimed.

主权项

1. An apparatus for computing, comprising:
one or more processors; one or more serial advance technology attachment (SATA) ports; and a basic input-output system (BIOS) to be operated by the one or more processors to:
determine, during a power on self test (POST) phase of boot up of the apparatus, whether a device is attached to a first of the one or more SATA ports;on determination that a device is attached to the first SATA port, further determine whether a receiver equalization margin has been set for the device; andon determination that a receiver equalization margin has not been set for the device, perform a discrete time linear equalization (DTLE) training to dynamically determine and set the receiver equalization margin for the device.
