Not sure exactly how/where to place this, but it ought to be added in some form.

[edit] Error 19
[edit] the background
- (from a FreeBSD forum post)
In any event, booting to FreeBSD from Grub now leads to
Code:
Mounting from ufs:/dev/ad4s3a failed with error 19
and thereafter to a mountroot prompt. Typing '?' at the mountroot prompt provides no GEOM managed disk devices whatsoever.
At this stage, I created a re-install CD of FreeBSD 9.0-RELEASE and booted from it. However, the boot ended with
Code:
Mounting from cd9660:/dev/iso9660/FREEBSD_INSTALL failed with error 19
and then the mountroot prompt. Once again, typing a '?' at the prompt showed no GEOM managed disk devices.
[edit] the solution
- (from a blog post)
Here's where I found it and all that is need is to open the loader prompt during the CD/DVD/USB boot (by pressing 2 or ESC) and adding the following line:
set debug.acpi.disabled ="hostres"
and then booting with
boot
Once the USB key has booted you can add the line
debug.acpi.disabled ="hostres"
to /boot/loader.conf, if you intend to use the key again. In any event, once you have installed FreeBSD 9.0-RELEASE, you still need to add this line to /boot/loader.conf.
