DOS ain't dead

VXD/LE file modification - unknown bytes in header (Developers)

posted by RayeR , CZ, 01.12.2020, 00:11

I'm trying to port some patch from one VXD to another VXD (a different driver version). I started with comparing patched and original file. At the beginning there are 3 different bytes at offset 144-146h - what is its meaning?
The file starts with MZ signature and common DOS stub.
LE header start with LE signature at offset 80h. I guessed that bytes are LE checksum but not, it's 0. I found some LE description but it didn't went too further to describe offset bytes at 144h - 80h. Any idea?

DOS gives me freedom to unlimited HW access.
