I am trying to install FreeBSD but I am having a problem. My computer is a Thinkpad T400.

I followed the instructions to install so I have downloaded the file FreeBSD-8.3-RELEASE-amd64-dvd1.iso and burned the ISO image to disc.

When I boot with the disc it comes to the Welcome to FreeBSD screen. But when I choose option 1 for Boot FreeBSD [default] nothing happens - it just stays stuck at the welcome screen like it is frozen.

Like in the instructions I tried to disable ACPI in the BIOS but I cannot find any option to do this. The closest I found is CPU Power Management which I disabled anyway. I also tried selecting option 2 - Boot FreeBSD with ACPI disabled - but nothing happens. All it does is stay stuck on the welcome screen.

I know the install disk is OK because it boots on my desktop computer (I abort the install). How do I install it on my Thinkpad?

I've run into a similar situation, so you're you need to either turn off ACPI or switch to an integrated video card only so the installation can continue.

Also, there's compatibility list you may check, you may submit your own as well.

Switching to integrated video worked and I am able to continue the installation. Thank you very much. – JoeyR Aug 20 '12 at 21:01
