OpenBSD and DMA
I recently tried installing OpenBSD 2.5 (release) on a 500 meg HDD (IDE)
on an i386, and halfway through the base25.tgz download, the computer
rebooted. I am almost positive it has to do with DMA, and how the HDD
can't handle it. I had the same problem with Slackware 3.6 a while ago,
because it was using kernel 2.0.36, which has DMA enabled by default
(plus the timeout messages clued me in). My question:
is there a way to disable HDD DMA before loading the kernel, or maybe
another way? I have UDMA disabled in my BIOS for all hard disks as
well. Also, there's an option for IDE PIO, and I'm not sure what this
does. It's set on AUTO as of right now, should I set it to something
else? Thanks for all your help.
