| Post subject: | Identify a ATA or SATA |
I am trying to identify if a ATA and SATA drives with the ECh command with the opcodes: Code: mov ax,00ECh out 1F7h,ax in 1F7h,ax but this code returns FFh in ax register and when I try to read 1F4h and 1F5h ports returns FFh in ax too. How can I identify if is a ATA or SATA drive using I/O ports? |
