Anaconda used to insert it. I must agree, however, that "ide=nodma" is a bad idea as it will slow down disk access. If your CD requires it, I'd recommend "hdc=nodma" (replace "hdc" with the device name for your CD) to disable DMA for that device _only_. ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens@xxxxxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - Okay, who put a "stop payment" on my reality check? - ----------------------------------------------------------------------
