Thanks.

However it showed dma  on hdc already on...

2K4 *ROOT* /home/brevard/DVD/videolan.org (99)>hdparm -d /dev/hdc

/dev/hdc:
  using_dma    =  1 (on)

... and a re-check of /proc/ide/hdc/settings also showed DMA ON!

2K4 *ROOT* /home/brevard/DVD/videolan.org (100)>cat 
/proc/ide/hdc/settings

SO, maybe my earlier ...

     echo using_dma:1 > /proc/ide/hdc/settings

... actually worked.
