Can A DVD Burner Be Connected To A DMA100 Channel???

[Robert Nurse]

Hi All,

I just bought a new DVD Burner: Plextor PX-708A. My motherboard, an
Asus A7V (don't laugh), has two Promise Ultra DMA 100 channels and two
Ultra DMA 66 channels. The primary DMA100 channel is taken by an
Ultra DMA HD. The primary DMA66 channel connects an Ultra DMA 66 HD.
The secondary connects a CDROM drive (master) and an LS-120 (slave).
Now, my question is, will the Plextor PX-708A function on the free
DMA100 channel? I don't want this drive to be a slave and I don't
want my two HD's to be slaves. I was thinking of making the Plextor a
master and the CDROM a slave to it and removing the LS-120. But won't
performance suffer when copying CD's from the CDROM? I've heard of
problems making burners and CDROM drives master/slaves to one another.

It could go on the free DMA100 channel if you want.

an LS-120 (slave). Now, my question is, will the Plextor

Yep.

I don't want this drive to be a slave

It'll work fine like that.

and I don't want my two HD's to be slaves.

You got something against slavery ?

I was thinking of making the Plextor a master and the CDROM
a slave to it and removing the LS-120. But won't performance
suffer when copying CD's from the CDROM?

Nope. Most modern burner software automatically
caches the contents of the CD to the hard drive.

I've heard of problems making burners and
CDROM drives master/slaves to one another.

Those problems are long gone with burnproof burners.

According to the Intel Application Accelerator on my computer, the PX-
708A only supports up to UDMA2 (UDMA33). Drives and controller will search
for the highest setting common between the two. You can put a modern 200+G
UDMA100 drive on an ancient 386 with a PIO IDE controller if you wanted
to. You could put an ancient 20M IDE drive on a modern UDMA100 controller,
and it should work.

Go ahead and put it on the free UDMA100 channel. It's the easiest
connection (if you don't mind even more cables snaking around your case)
and will give the best overall performance.
