So far, it's not clear to me that anyone has demonstrated how this is

about rom loading, then there's really no impact to users.
Fix (v2) is on the list already.
PXE booting might have security impact. You do not want to
do this if you are on a hostile network.
Option rom loaded doesn't imply pxe boot will be tried. It only means
PXE boot can be selected, either via
-boot order=[something with 'n' here]
or via
-boot menu=on + F12 + picking menu entry
By default qemu doesn't try to PXE-boot, even if no other bootable
device is available.

I guess so. But then, why are we loading it in BIOS
and wasting memory? Let's only shadow the ROM
when PXE is selected?
Some DOS-based software might need the UMA (RAM UMB).
