I have a KT600 chipset and the IDE drivers have 2 versions:




This one is part of VIA_IDE_MPD_V320b Viaide.vxd version 2.0.950.3020

^^^^^^real model ID^^^^^^^^

I can only obtain mode 4, but drives are identified.


This is from VIA4in1_v5.04 Vatapi.vxd version 2.0.950.120

^^^^^^type 47^^^^^^^

I get mode 6 but no drive identification


Viaide uses Viadsk.mpd
Vatapi uses esdi_506.pdr


So whats the deal, anyone mastered this one ?
I'd like to keep udma 6 and the drive identification, funny pcwizard knows what it is......

This is normal. With the 4in1 driver you don't install the IDE filterdriver. The windows default ( esdi_506.pdr) are used and that's why you only see type 47.
If this works better and in your case it certainly does, it's best to keep it like this.

Via claims that their own IDE filterdriver is faster. I tried it myself and it seemed a bit faster. But my Nero BurningRom didn't work anymore....
Problems with other software are also reported. I see that you have a DVD-RAM drive. I have a very similar one, the 4167B. I had problems with the DVD-ram software in combination with the VIA drivers (3.20B)

The Via drivers will give you your drivenames but in a strange way. All your drives will be recognized as a SCSI device.

Never those VIA drivers for me again!

Yes !
That's the problem, I used the 320 driver on my mode 4 and under days, the driver says it supports udma 6 but there must be a trick, I used to use the 2001 bus master with 2003 (320) primary and secondary on my 686b southbridge. The manual setting tools was bunk too so I updated from the unzipped folder.
Also if "synch data tranfer" on my harddisk's is scsi, then thats what it was, now it's dma and synch is greyed out.

The Via IDE Filter Driver adds support for those Maxtor ATA 133 speeds on Windows 9x. Windows XP includes support for that, so Via even removed the IDE filter driver from the latest Hyperion's.

I don't think you need it unless you use ATA133 hard drives.

What you should avoid it the Via IDE Miniport driver that they offer seperate from the 4-in-1's. That thing does fix parellel port Zip drives, but other than that it screws up cd drives and data transfer's.

I have a lot of Maxtor drives so I always installed the Via driver included in the Hyperion's or 4-in-1's. No problems with it here.

I can use the 320 driver in XP and it renames the mater UltraBusMaster and it has udma 6 but 9x seems to be limited to udma 4, so I'll have no choice but the 4in1 driver. I liked the non-type 47 ID's but oh well.
