UDMA settings for HTP366

[zeflash 0]

Hi everyone

 

I've recently installed RC3 with the new 1.20 HTP366 drivers & BIOS 1.21 on a BE6.

 

I've got a pioneer A03S DVD drive connected to one of the ATA66 IDE.

 

I was trying to understand why the DVD playback was SO crappy when I thought of the DMA settings we usually find in the primary & secondary IDE channel (as you all know, the default for CD drives is PIO only, you have to change that by hand).

 

Well, this "Use DMA if available" is not there on the Mass storage controller, corresponding to the ATA66 channels.

And I'm positive that this crappy DVD playback is a DMA pb as my DVD on a normal IDE channel with DMA activated works just fine.

 

Furthermore, if I try to keep my config like this & put my ASUS cdrom on one of the ATA66 channel, it freezes w2000 everytime I put a CD in it !

 

Anyone has a solution for this DMA setting pb ? some registry hack perhaps ?

 

thanx

so what software dvd player are you using? and you say it actually works in RC3 ? do you have the latest version of that HTP366 ?

I don;t think u can enable DMA for HPA66, I belive it is enabled by default. THough I haven't tryed hooking up my DVD on to it. But HD works fine.

Give the HPT366 a BIG miss...

 

I have played around with the HPT366 ATA66 IDE controller vs Intel IDE controller on an Abit BP6 with Windows 98 and Windows 2000 RC2.

 

CPU usage was ALWAYS higher using the HPT366 controller compared to using the standard (and very good) Intel IDE controller performing tasks such as defrag, searching for files and loading games.

 

Also, I noticed NO performance increase either. So why bother?

I need to use the HPT366 because I've got 3 HD, 1 cdrom, 1 dvd & 1 burner.

 

As you should have noticed, the DMA settings on the IDE channels under 2000 are NOT checked by default when it's a CD or DVD that is connected.

 

Therefore I'm quite positive (I've TESTED my DVD on the normal IDE & it worked) that the same thing happens on the HTP366, only pb is that you cannot set these settings.

 

About my DVD player, the only one that works under 2000 is WinDVD, either the one that ends with 99 (sorry I don't remember the name), or winDVD 2000. PowerDVD worked once, but now crashes. Cinemaster never worked.
