Hardware: Tyan Tiger LE (with ServerWorks OSB4 _and_ Promise 20267 on-board) Kernel: 2.4.3 with ide.2.4.3-p8.all.03242001.patch by Andre Hedrick (or stock 2.4.3 with more or less same results) FastTrack config: only 1 drive, configured as a SPAN volume consisting of 1 drive I don't quite care about the Promise RAID features. I will use Linux software RAID. The problem is that I cannot seem to be able to get the controller into UDMA 4 (66 Mhz) mode! I have enabled all the relevant DMA related kernel options. I have also checked using the Seagate disk utility to make sure that the drive is recognized (and configured) as UDMA 66 capable. The following is from dmesg: PCI: Found IRQ 10 for device 00:03.0 PDC20267: chipset revision 2 PDC20267: not 100% native mode: will probe irqs later PDC20267: ROM enabled at 0xfeae0000 PDC20267: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER Mode.
