IAA and different devices on ide channel.

[alfonso]

The latest version of Intel app. acc. claims that different transfer modes are available for both devices on an ide channel. Does this mean that an UDMA-2 cd or dvd writer (as shown in IAA tool) set as slave doesn't slow down the master UDMA-5 (as shown) hd?

I would like to have dvd burner without removing my great plextor cd burner, so I should put it as slave on the 2nd ide channel, where my audio hd is master...of course it would not work when making audio, but.......who knows better?

Thanks in advance

Chipsets have been in existence since 1997 that support <A HREF="http://www.pcguide.com/ref/hdd/if/ide/confTiming-c.html" target="_new">Independent Device Timing</A>. But you shouldn't mix and match PIO mode-only devices and those that are DMA.

Preferably, to avoid any issues such as CRC errors, or an optical device slowing down a faster device, such as a hard drive, it is best to keep EIDE devices on one channel, and ATAPI devices on the other, due to the differences in the command set structure, even if the chipset does support IDT.
