My TX97-E bios starts up my QUANTUM FIREBALL ST2.1A as UDMA 2, but linux
2.1.66 sets DMA off. I have to turn it on with hdparm. I am not clear why
linux does this. How does linux make its decision?
OTOH linux and the bios both start my ST51270A on pio 4, which seems
clearly correct as turning on DMA gives occasional timing errors.
