Vendor Specific Registers
This register contains the output bits associated with the two SATA drives and Vendor
Specific Message when operating in the AHCI mode. The bits associated with the drives
are intended to control LEDs (e.g., activity, fault, and locate LEDs). It is the
responsibility of software to write data into this register. Three data bits are allocated
per drive.
