Hello,Current QEMU-KVM VGA implementation have the following problem with legacy OS (e.g. DOS with INT10h calls): Performance is low on accessing A000:0
page and doing bank switching at the 64k page. Would a kernel mode VGA solve these problems? How complicated is it? Is it possible to have only some parts in kernel mode? Any further ideas or suggestions? Thnx. Ciao, Gerhard -- http://www.wiesinger.com/
