Maybe LBA48 will work in PIO mode. ALi does support LBA48 in PIO mode. Right now the choice is DMA and 137Gb or no DMA and 200Gb, ideally it should be DMA and fall back to PIO for the top 70Gb, but not yet a while. I've actually not yet found a controller in my testing that cannot manage LBA48 PIO, including nailing a 160Gb drive to a Cyrix box with a VIA VP2. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
