I see that unmasking IRQs is disabled on my machine (I'm using the default settings, so only DMA it seems). Is unmasking IRQs dangerous at any time ? Is it dangerous when having 2 devices on the same IDE channel (both CD-Rom and HD are on the first channel on this machine) ? And if it's not dangerous at any time, why isn't it enabled by default ? ;) "We need some IDE experts here" ;) Cheers -- /Bastien Nocera http://hadess.net
