DMA won't enable...

[SoulSe]

This one has me stumped! Thanks to chrisz, I now know more about hdparm and hd features, but still no success, here is the sad story of SoulSe the Geek....

 

I have an ASUS A7V600 MoBo that I am using with an old Maxtor 40GB hdd, 5400rpm.

 

When I boot Gentoo, I get an error saying that the DMA on my disk is not enabled and that this could seriously retard the fsck process.

 

So the first thing I did was try to enable the DMA using hdparm, this informs me that I do not have permission (yes, I did it as root... geek, remember?)

 

I am almost 100% sure that this is not a problem with my kernel compilation either.

 

hdparm -tT /dev/hda shows me a speed of around 4.8 MB/s - too slow IMO.

 

There must be a good reason why hdparm won't allow me to set DMA on

the drive? Can I add hdparm to my boot schedule with rc-update? Or is this the wrong way to do it?

 

I know I should do hdparm -d1 /dev/hda and then make it stick... but it won't do it...

 

The ASUS MoBo has RAID as well.

Do you have an option in the BIOS to "enable" DMA?

i think that's hdparms way of saying it won't or can't do what you're asking. I got it once, but can't remember the details. Will hdparm do -I

hdparm -I /dev/hda

 

and what does it show the hd settings are?

hdparm /dev/hda

 

Could simply not be happy about the raid or something.

 

What are the bios setting? Defualt? or User Defined? Make sure all settings are conservative for ide/hd's. Fixed my prob once when hdparm would actually cause worse settings than the default. When I set the hd to Auto in the bios and used hdparm, it worked.

Isnt their a module in webmin to test hdparm settings? Cant remember of hand (not at home). Still may not work but worth a look.

Thanks for the advice!

 

There does not seem to be anything in the BIOS that will relieve my pain, I also posted on the Gentoo forums and nobody seems to know.

 

So I reckon I'll compile a 2.6 kernel and see if I can iron it out. Has anybody used one of the boards? Would anyone be able to give me tips for the right modules I should compile? A full spec. sheet for the board can be viewed here: http://www.asus.com/prog/spec.asp?m=A7V600&langs=01

 

It has all the chipsets for the onboard LAN, etc. listed, perhaps somebody has the same chips?

 

That would be super-duper.

 

Thanks again ;)

w00t! ASUS have some Linux drivers for this board:

Can't install though, this is the error I get:

DMA is working. Compiled 2.6.1 and that sorted it out.
