Hi all,

is it somehow possible to determine what is the fastest UDMA-Mode my IDE-Controller supports - independant of the chipset?

Thanks,
Michael

Not really. You have to know the specific device to know how to query the modes it supports (if indeed you can query and don't have the driver knowing by type)
