Hi all.

Would it be possible to add some DMI based quirks? I have a device and
in coreboot I have
some detection code for it:


Now it takes quite some time to load Grub in PIO mode even the device
could use DMA.

For the linux kernel I have added this patch:


What would be the best solution in seabios to use PIO for broken devices and DMA
for the others? The biggest problem is that the device supports DMA
but due a missing
resister I breaks in DMA.
