I updated drivers of the Primary and Secondary IDE Channels, and information
about DMA mode disappeared from the Channels Properties. How to know the DMA
modes for the IDE Channels?
 
Hi,

Control Panel/system/hardware tab/device manager, click view-->"resource by
type", expand the IRQ branch, double-click the controller in question. On
the Advanced Settings tab, it will indicate the DMA mode in use for each
drive attached.

If you installed "enhanced" IDE drivers (also available for my Asus A7N8X
M/B), the IDE ports will show up as SCSI devices. It is "assumed" that all
are in UDMA mode 5 (by default).
 
I don't know what was installed. I just chose default options in the Update
Driver Wizard. My motherboard is Asus too.
 
Hi,
The Advanced Settings tab disappeared after updating drivers of the IDE
Channels.
 
Rollback to the previous versions.

Are your HDD's DMA compliant? Are you using a DMA IDE cable (80
channel) between the board and drive?

Yes. The HDD's are DMA compliant. Yes. I'm using a DMA IDE cable (80
channel) between the board and the drives.
 
Why should I use 80 wire cables for a upto UDMA 33 motherboard? They
supplied 40 wire cables with the mainboard.

The previous versions set PIO mode although "DMA if available" was

selected.

Those will be the standard drivers, and if they go into PIO like that it
indicates that for some reason there has been a error rate that was
found unacceptable, so it has fallen back, and stuck. In the
circumstance this may be spurious. Check cabling and so on; especially
that you are using 80 wire cables for devices at UDMA 33 or faster, then
highlight the top level controller in Dev Manager (just above 'Primary')
and Action - Uninstall. OK and reboot for PnP to start afresh
