Here's my recipe for setting the primary hard drive to silent mode:
- Enter OpenFirmware by holding Command-Option-o-f at startup.
- Enter the following line:
0 0 0 here 428000 , ef , 4000 1 apply ata-command hd . - Hit return and check the output (if it prints 0, it went OK)
- To go on booting, type mac-boot and hit return.
The bad new is that Barracuda drives don't support AAM.
[robg adds: Take care when using open firmware; you can cause some bad things to happen if you mess something up. I have not tested this hint...]
