how this parameter works?


ihave a weird cdrom taht requires me to append parameter "ide=nodma" at boot.
what does that mean?

to be or not to be, i somewhat feel a slight performance hit each time i use that parameter to boot..

does it actually can cause a slowdown?

thx

Well yes it will slow things down, as you're not going to be usig dma on your ide channels. not sure how relevant that would be... shouldn't ever need to disable it on ALL drives... how does it not work if you don't do that? try hdc=nodma (assuming the drive is on hdc - secondary master)

ah thank you... i'll try that 1.. is that mean only the hdc will be turned off its dma mode, and my harddisk will continue to use dma?

that parameter is required so that the cdrom can mount cds....

thx
