I want to provide an example file system driver for Windows NT/2000/XP. For some time I have worked on an implementation of RomFs. RomFs is a small filesystem originally implemented in Linux, because of its simple disk layout its a good choice for an example driver. The current status is a working read-only driver that supports caching of file data, the create functionallity still needs some work but I m releasing it due to the high public demand.

To review what a metaball is, and how to render them and to describe a new optimization I ve made for rendering metaballs. For complex scenes, it can render hundreds of times faster, though I m certain others have discovered this trick as well. It does very slightly change the characteristic shape of the blobs, but there is no loss in image quality whatsoever. (I actually developed all this about two years ago, but just now felt like writing it all down, and had the time!)

This is a program that I wrote many years ago. It is a floppy disk , disk copy,disk info,and format program. All written in masm assembler. There is also a small 252 byte driver that allows nonstandard floppy formats on dos systems below 7.0. Floppies can be formatted in any track and sector layout. 1.44M floppies can be formatted to 1.76 M. All source code,includes and libraries are included. Modify the bld.bat file to your own needs. There are many asm tricks in the source code. Have fun with this old code.
