Hi,
We are faceing one Problem in Qemu guest os winxp . The Qemu hbas been installed in Linux CentOs 4.4 . Guest os detected the Realtek Lan Adapter . BUt with is Adpeter we are unable get the IP from Our Dhcp Server. Could you suggest how to do this. Regards Manish On 12/6/06, Miroslav Novak <[EMAIL PROTECTED]> wrote:
I'm sending some more facts that should make clear why I think the functionality provided by the patch is relevant. (At least for the DOS emulation.) Making emulated CPU slower Some old DOS games runs too fast on modern CPUs, even the qemu-emulted ones. This patch can make these games playable. The problem was reported in http://qemu-forum.ipi.fi/viewtopic.php?t=1264 Energy saving MSDOS doesn't use HLT insn. Even if the dosidle can help in command prompt, it doesn't work in other programs such as games. This was reported in http://qemu-forum.ipi.fi/viewtopic.php?t=1372 The similar approach is used in dosbox by setting "CPU cycles". I think qemu is better than dosbox, so it makes sense to me to include such capability too. This patch doesn't try to emulate the task scheduler that was why Martin voted against it. I'm sorry if I wasnt't clear enough in my first post. Mirek.
