2.0 on a bootcd
compilation, finally i found the possibly bug is in vfatfs.sys i
modified some lines but is not my code.....it seems to install Firefox.
Also, testing firefox i found problems with gdi and also done some
modifications, still testing them..
Here is my patch..NO WARRANTY he he..

The TEB can't be NULL, and why did you re-enable James' disabled code?
He disabled it for a reason. How is this related to VFAT?

This almost look like a robot-generated patch of completely random,
useless and broken code changes. How is any of this useful to FireFox
and VFAT?
Best regards,
