FreeBSD 5.4/6.0 on Virtual PC 7?

[David Paul Zimmerman]

Hi, all.  Both FreeBSD 5.4 and 6.0 are giving me strange behavior when 
I try to install them in a Microsoft Virtual PC 7 virtual machine.  
They'll both happily boot from the ISO images, and I can get through 
much of the configuration process.  However, at the point that they 
want me to choose the installation media, I select "CD/DVD" to continue 
using the ISO image that I booted with, and I get:

	No CD/DVD devices found!  Please check that your system's
	configuration is correct and that the CD/DVD drive is of a supported
	type.  For more information, consult the hardware guide
	in the Doc menu.

This leads me to think that the BIOS and/or bootloader has a different 
view of the virtual machine than the booted kernel does.  Even more 
interesting is that FreeBSD 4.11 not only boots from the ISO image 
fine, but also recognizes it for use as installation media (that is, 
I'm able to do a completely off-the-network installation of FreeBSD 
4.11 in VPC7).

Here's the output from dmesg on FreeBSD 5.4 (booted from ISO image, but 
used FTP as the installation media, later cvsup'd to 5-STABLE):

Any thoughts?  The "PNP" errors look relevant, but I'm not enough of a 
device kinda guy to interpret them.
