Hello, I just solved I problem I had for a while and wanted to share my experience, so it doesn't get lost. Situation: Debian CD writer (on hdc) kernel 2.4.20 devfs # hdparm /dev/hdc /dev/hdc: No such file or directory # hdparm /dev/sr0 /dev/sr0 not supported by hdparm Problem: How does one setup DMA in this case? Solution: You must create a /dev/hdc device node for hdparm, you cann't do it in /dev, because devfs wouldn't let you to. So: # cd /root # mknod hdc b 22 0 hdparm works now! # hdparm -d 1 -X 34 /root/hdc /root/hdc: setting using_dma to 1 (on) setting xfermode to 34 (multiword DMA mode2) using_dma = 1 (on) :))))))))))))))))) -- Best regards, Aigars Mahinovs mailto:aigarius@debian.org #--------------------------------------------------------------# | .''`. | | : :' : Debian GNU/Linux & LAKA | | `. `' http://www.debian.org http://www.laka.lv | | `- | #--------------------------------------------------------------#
