on all combinations (I hope)... Add DMA support for the AMD 756 chip (K7 chipset) this is actually the same as the VIA 82C686 chip (the ATA part that is). Treat the intel MX chipset PIIX as a PIIX4 Allow UDMA on all disks that say they can handle it. Cleanup probe printf's a bit Remove alot of the old #ifdef DEBUG crap.
