- This program implements a Video Fossil (VFOSSIL) as outlined in the
- document FSC-0021.DOC available from 1:105/6.
-
- There are three programs included in this archive:
-
- VFOS_IBM.COM - VFOSSIL that uses direct screen writes.
- VFOS_BIO.COM - VFOSSIL that uses BIOS int 10h.
- VFOS_DEL.COM - Removes a VFOSSIL from memory.
-
- To use either VFOS_IBM or VFOS_BIO, just make sure that Opus!Comm
- 5.00 or higher is installed first, then run the program you wish to
- use. I understand that at the current time X00 does not support the
- hook necessary to use a VFOSSIL (Ray is working on it now that he
- knows about the problem). If you wish to remove the VFOSSIL, use
- VFOS_DEL. Make sure you remove the VFOSSIL before removing Opus!Comm
- (if you do things like that). Otherwise you will fragment memory.
-
- If you can use VFOS_IBM (using a video adapter that does not cause
- "snow"), you should use it. It is VERY fast. If not, try using
- VFOS_BIO which should work with multi-taskers as well as cga's that
- have "snow" problems.
-
- VFOS_IBM will automagically detect the presence of a monochrome
- adapter and write directly to the proper memory locations.
-
- Neither program is a complete VFOSSIL. There are several functions
- missing out of each version, or routines that function incorrectly at
- this point. The functions that are used by BinkleyTerm are known to
- be working in both versions. Other functions will be fixed and/or
- added to make a complete VFOSSIL as time permits (right now I am too
- busy with work and trying to get BinkleyTerm ready for release).
-
- I think this version of VFOS_IBM will find the "shadow buffer" under
- DESQview. It might even work under DoubleDOS, but I'm not sure. Let
- me know what happens.
