bus master dma error when installing

[Heinrich Rebehn <rebehn_(_at_)_comm_(_dot_)_uni-bremen_(_dot_)_de>]

Hello,

I am unable to install OpenBSD 2.9 on our new server. After asking for 
the root disk and wether to use all of the disk, the kernel reports:

   pciide:0:0 bus-master DMA error, missing interrupt, status=0x20

and the install program then hangs.

This is a 1.33 GHz Athlon machine w/ a Gigabyte GA-7ZXR Rev. 3.X board 
and i am trying to install on a 20 GB IDE disk.

I searched the archives for this problem, but only found a message from 
someone who had this problem on first boot after install. But he didn't 
get any reply.

Can I use the kernel config option (boot -c) to switch to a lower DMA 
mode? How is this done?

Thanks for any help
