We could always eliminate lba48 max-sectors increase on VIA controllers...



Has Brad tried it with native SATA drives instead of bridges? Could be
VIA controllers incompatible with PATA->SATA bridges.....




Oh wait.  That's a damned good point.

I wonder if there is a problem with LBA48 large transfers (>256 sectors) and bridges. Is Brad definitely using a bridge? I may have missed that detail in a flurry of emails :)


Yep.. using a bridge!
How to detect the bridge though?

It's not terribly easy :/

If you can google for the datasheet, that would be helpful.

Sometimes bridges will modify the underlying 40-char ATA model name,

	WD123456                        ADDONICS68

where "WD123456" is the underlying ATA device, and "ADDONICS68" is the bridge identifier.
