Hi, I was monitoring this thread since I have a similar problem with my Compaq 1260 Laptop. DMA worked until I upgraded to SuSE 8.2. DMA still works under Windows. Did you ever find a solution to the problem, if yes, what was it?
Thanks, Richard
No solution, as yet. Seems DMA can be enable, somehow, upon bootup but I have yet to spend much time looking to see where that might be.
Yast>Hardware>IDE DMA Mode
My IDE interface is an OPTI 82C825. No matter what I put in the IDE Setup for IDE DMA Mode I get the same error message " Error occurred while activating changes." I've gone into Grubb and entered the supposedly correct info but no joy from there either! The lack of DMA makes the laptop almost unuseably slow!
So far I havent found out enough to let me look into the innards of the mode.
thanks for the response. Richard
I just found the following message from Alan Cox in the Linux kernel Archives which may tell the tale:
I checked my logs and found that the 2.4.21 kernel use E-IDE version 7.00beta[34]-.2.4 and the 2.4.20 one use version 6.31.
Looks like something went wrong in the IDE code regarding DMA settings ?
Here is the output from 'lspci' for my IDE controler (Toshiba Satellite 2540CDT):
It used to be caught by the generic DMA driver that would just run with BIOS settings. This approach unfortunately also tended to grab devices that didn't work with just BIOS settings so I took it out and just left a table of known OK devices. I'll add the toshiba one back and I've also pinged Toshiba to see if they will give me the docs to support it properly. Alan I guess we should be talking to Alan to get the support back for our respective controllers. RA -
