Thx for reply. I tested it and I wonder how can I get so incredible low speed with /dma, just 46kB/s :-P It doesnt matter what dma mode I select and if uide is loaded or not. Here I teste bare DOS, see logs:

I don't know if usefull, here's output of DMACHK.COM:

DOS gives me freedom to unlimited HW access.
