I suppose it is the same for HD 4400?

Any idea if this is present in Yosemite? I might just try and upgrade.

I have a 7537 and I followed this guide and installed Mavericks successfully. When booting though, the apple screen flashes repeatedly. When I log into the desktop, I see no graphics issues and everything appears to be working properly. Is there any way to stop this flashing as it is very annoying during boot?
