Yes. And merge the bit which resets the PAM configuration in the i440FX on a hard reset. And make sure that suspend/resume, keyboard controller, etc., are *not* hard resets. > Or is the lack of big real mode at startup on non-unrestricted > mode boxes also a problem? No. > I never quite understood how the two related to each other in this thread. It's one or the other. If big real mode actually worked, we'd run from 0xfffffff0 after reset (*any* reset), and we wouldn't *care* what we get when we read from 0xffff0. Since big real mode is broken, we *do* care what's at 0xffff0. And thus we need to make sure that after a *hard* reset it's the ROM (OVMF), and after a *soft* reset it's still RAM (SeaBIOS after it's done its init, and can find the ACPI resume vector, etc.) -- dwmw2
