Failure to install on AMD64

Hi,

I tried to install NetBSD on my AMD64 system, an nForce 3 system from
Compaq.

I was able to boot from the CD and install to the HD ok.  However, on my
first boot, I get "Error Not a bootxx image."  I tried installboot, but
that did not help things.  I can boot from the CD, pass a kernel a
param, and give it /dev/wd0a and it appears to boot OK then.

However, it does not see my Ethernet, the nforce3 built-in one.  On
Linux, this is the heatdeth driver.

Any suggestions?

Thanks,
John
