Dma

[mill]

I was reading a little on dma settings and was wondering about why my new pc when i first got it and checked the dma settings before it ever had any crc errors started at ultra dma2 under primary ide and not ultra dma 5. Im under the understanding that 5 is the faster then 2 and as you get crc error's it drops down 5-4-3-2- and then finally pio mod which is the slowest and mainly uses the processor.

Your HD should be UDMA5 or 6. Perhaps your burner was connected to primary as slave? It would report UDMA 2.

mill you have serial hard drives and almost all optical atapi devices are dma2, which at 33MB/s is plenty fast enough

your real problem was the ide driver if I remember

Chaulk it up to nvidia and asus and the builder's not understanding the
interaction between xp sp2 and mobo driver disk cd!
When loading the computer always let windows use native drivers and be very cautious about using the ones from an often out of date installation cd.
And just because you get the latest from the mobo manufacturers web site doesn't mean they are safe, look at the dates.
On my nf2 asus mobo this driver hosed the ide for my burners and combo ripper.

2003/01/29update NForce2 all in one version 1.16 driver for WinXP

when I reloaded I let xp use it's own driver

Chewy, my motherboard is an ASUS A7N8X Deluxe (v2). Are you saying that there's no need to download and install the nvidia nforce 2 driver? That the native drivers that come with XP (and 2k?) are better for the motherboard? By the way, I use Windows 2k Pro as my OS.

not sure about W2k, it had lots of dma problems, but if it has native nf2 support use it.
