DMA support for ibm DADA-26480

[radx 0]

I got a HP Omnibook 4150 with the IBM DADA-26480 6.4GB harddrive. Now when i look at hp's webpage there is a bios especially made for win2000, that is installed. After i did a clean installation of win2000. Now i cant get anyother transfer mode than pio mode from this disk. Question, does it support DMA mode?

 

Now i looked at IBMs webpage

http://www.storage.ibm.com/techsup/hddtech/dada/dadades.htm

It told me this:

 

Interface transfer rate (MB/sec) 33.3 MB/sec Ultra DMA mode-2

16.6 MB/sec PIO mode-4

 

Meaning? It does?

 

In win2k device manager it seams it does not. Its choosed to be dma if available but still it says PIO mode only..

 

Any ideas?

 

Thanks
