To be more complete : Bios will panic if it founds prefmem BARs in both 32bit and 64bit areasOn Thu, Dec 29, 2011 at 06:41:36PM +1300, Alexey Korolev wrote:Can't figure this out. What does this do?Bios will panic if it founds prefmem BARs in both 32bit and 64bit areas.That's not good, it's a legal configuration.
on the same secondary Bus.I agree about that this limitation is too strict at the moment. But this is just a limitation, there are
plenty of them in Seabios.To answer if it is a legal or not we need to have a look how real BIOS would behave in a such scenario. Unfortunately I have no chance to have this configuration on hand. If you have (may
have) this I would appreciate if you let us know how the Bios will behave?
