Hi
I have a problem that is somewhat similar in that I also have a computer with Intel integrated graphic. It's a Zotac ZBOX with Intel Celeron N3050 and Intel Graphics with PCI Id 8086:22B1.
I can confirm that text output in real mode during booting is really slow, although that is not the problem.
I did a fresh install of Windows 7. When I start any program that needs DOS mode, NTVDM starts and uses 100% of one CPU core. It happens with every program, like command.com. This is not just a 10 second delay, I waited for more that 45 minutes and nothing happens. This happens in window mode and even with remote desktop. When I try to switch to fullscreen, I get the message that fullscreen is not supported by the system. It also happened before and after I installed the driver for the Intel graphics.
I tried the utilities from this thread, but without success. conhost_pat says "cannot open file for writing", but Process Monitor doesn't show that it tries to open any file. The others seem fine but don't change anything.
Do you have and additional hints what I can try?
