Dave,

Can you try this?

Look in the BIOS for the Option "AGP Aperture Size and change it to
128MB or smaller.

FreeBSD seems to have problems with Aperture Size greather than 256.

I could install freeBSD with 256 but not start it.

The installer fails with 512 MB with the same error message.

Let me know if that works, and we'll make an FAQ out of it.
