Detailed description:
|
||||
The bochs-executable does not follow typical
|
||||
unix-conventions for command-line arguments. The
|
||||
included script Bochs.sh is a wrapper for bochs.
|
||||
|
||||
Patch was created with:
|
||||
diff -u
|
||||
Apply patch to what version:
|
||||
release version 1.4.1
|
||||
Instructions:
|
||||
To patch, go to main bochs directory.
|
||||
Type "patch -p0 < THIS_PATCH_FILE".
