Upon further experimentation, it seems that if I remove the CF disk from the system, then the PATA drive boots and runs with DMA enabled. The CF card I'm using is marked externally as a "PNY" 512MB CF card. It probes as "TOSHIBA THNCF512MMG 3.10" at boot time. With it running in UDMA100 mode, I get about 4MB/s of transfer rate, about twice the PIO4 rate, and of course with a lot less system time! I have some UDMA-cable CF cards on the way that I'll try next to see if there's something toxic with the PNY card I have now. Though I did just see phk's note regarding the Sandisk Extreme IV cards, so I wonder what new and interesting things I will find next? louie _______________________________________________ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
