Well, after having 0.7.something on this ol' Thinkpad for, well, since that version came out, I finally got off my kiester and I'm running 0.8.4 now.

What's perplexing me is this boot message:  Skipping DMA acceleration as requested on boot command line.

I can whup it up with hdparm because this IBM hd subsystem supports UDMA2.  0.7 supported that by default, so there's something a little bit different about 0.8.  Either that, or I botched something.  

So I'd like to get that boot command line thing changed.

Can some on point me to the file that needs to be tweaked?

Thanks!

lilo.conf might help (you must run lilo from xterm after editing or your pc may never boot again)
just look and see if the relavent is there, if so then ask for further help before editing.

Nope.  There doesn't seem to be anything in there to tweak unless there's something MISSING that needs to be added to turn on UDMA2.

I was also thinking of merely adding the hdparm thing in Linux's equivalent of autoexec.bat.  But, I forgot where and what that is.  I humbly seek a memory jog.

Thanks!

dma is turned off by default, do you really need it?

Did you place:

dsl dma


in the boot command line?
