I said I'd never seen this (true), but it could happen if you were burning an audio CD using the ide-scsi or ATA: interface. In 2.6 the ATAPI: interface uses DMA. I don't know what the program does if you just say dev=/dev/hdx, I don't normally use it that way (I got into the habit of using ATAPI:). Given a fast burner and the interface using PIO, I guess you could slow the system down some! -- -bill davidsen (davidsen@tmr.com) "The secret to procrastination is to put things off until the last possible moment - but no longer" -me
