It's also useful to try modes other than PIO4 when using the finer-grained mode= control. We've been disabling dma completely on SBCs with CF sockets for years due to the kind of lockup you mention, but I recently discovered that some units run just fine with mode=WDMA2 (but not any dma modes faster than that). -- Ian ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
Disable DMA.
Hi, In FreeBSD 8 i used the loader-variable hw.ata.ata_dma=0 to get my computer boot on a CF card. But in FreeBSD 9.0 it doesn't seem to work. Could it be another variable or is it something else that doesn't work in 9? The machine boots up the installer when the CF-card is not present but when it is present it stops right after the Timecounter stuff. -- Peter Ankerstål pe...@pean.org http://www.pean.org/ ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

Disable DMA without loader.conf or sysctl.conf.
Hey guys; I'm back to using FreeBSD, after my major hardware upgrade seriously broke everything (teach me to optimise...) I've stuck it on my xbox for now, and it runs like a charm, of course, except it complains then dies on boot about the HDD having problems with DMA. It's only using a 40-conductor cable, and 80 works fine, but the cable is a special length; I need to use the provided one to shut the case! Is there _any_ way to disable ata DMA at kernel compile time? Remembering that Cromwell won't support loader Thanks a lot Chris -- One of the main causes of the fall of the Roman Empire was that, lacking zero, they had no way to indicate successful termination of their C Programs.
