Can someone explain why the ATA command Identify Device (0xEC) has the
following test in the switch statement:
case 0xec: // identify device
if (p->sectors != 1 || ndp < 512)
return -1;
Given that the ATA spec says that the sector register is N/A (as are pretty
much all the rest) when making this command I don't know why the blade
server requires that submission of this command have AoE ATA command set
sector to 1?
I have my suspicions but I would like to hear from others...
