Over the past few weeks, some readers have come across a bug that causes xp safe mode to hang on mup.sys. This problem can occur for several reasons. We will review them now.
What Is MUP For Windows Sys XP?
Mup. sys is a Windows driver. A driver is a small piece of software that allows your computer to communicate with the Universal Serial Bus or connected devices. This means that each driver has direct access to all the internals of the operating system, hardware, etc.
XP Friends Will Not Boot
Using qemu and vmplayer, I created a vmdk file (and the exact same vmx) containing a complete Windows installation. Now I’m trying to go directly to Virtualbox, but the machine I created with the specified vmdk file won’t start. When booting in safe mode, it blocked agp440 on .sys. I found this page http://www:.virtualbox.org/wiki/Migrate_Windows, also went into system files and corrected the agp440.sys.backup name. Now Mup on.sys crashes on startup. Just to test, I also renamed mup.sys to mup.sys.backup if that’s the case, but it was hanging on NDIS.sys. I don’t know what is the reason as the application worked fine in VMPlayer and Vmware Server.
