The following entries are not clear to me, i.e. risk vs. benefit. I have UDMA33/66/100 devices, and am considering enabling ATA_ENABLE_ATAPI_DMA on a pci bus. While I could send this query to -questions, I'd like the response to be reflected in the Handbook. http://www.FreeBSD.org/handbook/kernelconfig-config.html options ATA_STATIC_ID #Static device numbering This makes the controller number static (like the old driver) or else the device numbers are dynamically allocated. #options ATA_ENABLE_ATAPI_DMA #Enable DMA on ATAPI devices This enables DMA on the ATAPI device. Since many ATAPI devices claim to support DMA, but it does not actually work, this is turned off by default. -- Randy Primeaux randy@cloudfactory.org FreeBSD - the power to serve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-doc" in the body of the message
