I have searched and read lots (if not all) threads containing the faint mention of BSD in them and did not find the advice or answer I am searhcing for, so thus this thread. I am at this moment running FreeBSD 5.1 and I am trying to install OpenBSD 3.3 (Orig. CD not downloaded) and it's just not getting past the boot sequence. This is the maschine I am trying to install upon:

P4 2.66 GHz
512 DDR
2x80GB HDs
Megatrends Board
CD-ROM/CD-RW + DVD Player
all aother stuff is not worth the mention.

Now this is the error msg I am getting
wd0(pciide0:0: timeout
type: ata
C_bcount: 512
C_skip: 0
pciide0:0:0: bus-master DMA error: missing Interrupt, status=0x61

I have tried lots(not everything) and searched, read(even outdated literature) and nothing turned up a possible answer to get around this. I have also tried deacvtivating pcibios by entering "boot -c" and then "UKC" this did not help. I know someone out there has an answer, atleast a logical/feasable one that may help.

Ohh: Megatrends bios does not allow deactivating DMA, you can only switch betwenn PnP/ISA.
