Using this parameter forces all CD like devices (CD, CD-writers and DVD drives) to use Polled I/O mode, which is definately 'slower' for most DASD (Hard drives), but may not appear slower for CD drives. If you use the ide=nodma parameter, you can see the effect of placing the entire IDE interface in PIO mode (it is much slower than DMA mode.) -- James McKenzie Running Fedora Core 3 on a Thinkpad A22p with Software Suspend 2 and ibm-acpi .1.
