The ATA specification specifies the maximum response time for many commands to be 30 seconds.

Sounds like something that should be commented in the source code. IDE_TIMEOUT = 32; // 30 seconds per ATA specification +2 seconds thrown in for safety On Sat, Jun 1, 2013 at 3:21 PM, Kevin O'Connor ke...@koconnor.net wrote: On Fri, May 31, 2013 at 03:18:56AM +, Gonglei (Arei) wrote: IDE_TIMEOUT is defined 32s.

The problem I see with that approach is that coreboot would need to add all of these files for a family14 mainboard.

The method I proposed would have one family specific vendev-map.bin file. Yes, but it would be quite difficult to inspect vendev-map.bin. I think an ascii interface is preferable. One could go a level up and make a symbolic link type in cbfs (this is effectively what my patch did). The advantage would be that cbfstool could display it in a nicer format. -Kevin I agree with that, and marc made the same suggestion. I'll put together a new patch next week.
