I've recently installed a Ultra133 TX2 (PDC 20269) in a box, and it also only does UDMA33 in 2.4.20-pre11. 2.5.44 with the PDC driver for "new" chips does UDMA100, however. (The disk is only UDMA100.) The latest 2.4.20-pre-ac is supposed to have new IDE drivers, but I haven't had time to test it myself. > So I have come to the conclusion there must be some rather bizarre > incompatibility between the PDCs and this motherboard.
