DMA not available for hard drive on DEC HiNote Ultra 2000
Last modified: 2007-04-18 12:58:46 EDT
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
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):
During installation - without entering "linux ide=nodma" installation is
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"
Pathologically slow performance
Faster performance than DMA disabled!
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.
