I have the same problem (i think) on a HP dc5850. In my test I've installed OpenBSD 4.7 on a USB drive and have sucessfully testet OpenBSD on several computers :) But when I try it on the dc5850:
Attempting Boot From USB Device Using drive 0, partition 3. Loading... probing: pc0 pci mem[ it hangs. I also tried to start it with the 4.7 CD's (I tried both i386 and the amd64 cd) with the same result. I tried setting the "Integrated Graphics Memory Size" to a fixed size (64 MB) because I noticed that it hangs on "mem[", but I really have no idea if this could possibly be related to IGM, I am troubleshooting blindly here :S Any pointers on what man pages to look at, bios settings, anything at all really, would be nice. If you need more information to be able to help, please let me know. Thanks! >Hello, > >I tried to install OpenBSD on an HP Compaq 6005 machine, but it's not >booting OpenBSD from a CD-ROM.
