There are operating systems that simple conflict with some assumptions

Rembember that the PC memory map changed to include the PCI
configuration space and so on, space that can be expected to contain
other data, or not at all, and could be used in ISA/EISA/VLB/MCA
systems by PCI-unaware operating systems or applications.
But practically speaking, given the devices that we emulate, is there
any workload that works with -M isapc but not -M pc?
Having to support an ISA and PCI system in the BIOS is a bit of a
burden. If we can eliminate that without regressing any guest
workloads, I think it would be a net win.
