Description of problem: DMA not available for the stock IBM hard drive on DEC HiNote Ultra 2000. It IS available under e.g. Windows NT. Have to boot using ide=nodma or else enter /sbin/hdparm -d0 An early symptom, maybe, is a message saying "BIOS not fully configured" and "channel 00.08.00 unavailable" during boot. I am running the latest DEC release of the BIOS - v.1.07 Version-Release number of selected component (if applicable): Linux v.9 How reproducible: During installation - without entering "linux ide=nodma" installation is pathologically slow. Once installed - setting "/sbin/hdparm -d1" hangs the machine. Steps to Reproduce: 1. Either - try installing from CD with default procedure, 2. Or, try "/sbin/hdparm -d1" 3. Actual results: Pathologically slow performance Expected results: Faster performance than DMA disabled! Additional info: Latest BIOS from DEC (i.e. HP!) installed and hardware checked. DMA works under Windows NT. "hdparm -I" shows that even udma2 should be available for this disk.
