Those are called "checked builds" and are freely available to students 
through Microsoft's DreamSpark program.
In addition to that you'll need another system running WinDbg (on 
Windows), and an EHCI USB debug or serial connection (no pci* serial 
card with mmio, it needs to use io ports).

Most of the issues I've seen so far were somewhat ACPI related (except 
for one due to a messed up Int10 handler, ie VGABIOS), and I collected 
some bits and pieces on http://coreboot.org/ACPI.
ACPI debugging is _much_ more powerful with checked builds than without, 
but for other issues the additional asserts, symbols and lower 
optimization level are useful, too.

However they're of limited use when trying to find issues in the 
installer, since that (at least up to Win8) is non-"checked" even on 
checked build media.
