This stuff is mostly self explanatory, but: part takes one optional argument, which is the disk number with which to start (either 0 or 1. 0 is default). 286pd1.sys and 286pd2.sys are for driving partitions on your first and second disks, respectively. They will only work on 80186 or higher processors. For 8086/8088 computers, use pdisk1.sys, pdisk2.sys. They are just a *wee* bit slower.... fdins is for use when you're short of free space in "low menory" -- i.e. free interrupt vectors. fdintins, on the other hand, doesn't use up any application space memory. In either case, these programs don't do *anything* directly -- you run them in order to create a .COM program that does the dirty work. You get TBL1.com, TBL2.com, TBL1INT.com, or TBL2INT.com, depending on whether you run fdins, fdintins and specifiy disk 1 or 2 (== 0 or 1). pformat is for when you want to be particularly destructive with your new partition. You run "pformat :" where must be a valid pdisk. It's good for marking newly developed bad sectors, I guess. Be careful. According to tests I ran with the PC Magazine benchmark program, disk access to a pdisk is actually faster than the normal DOS driver (i.e. C: or a DOS 3.3/4.x extended DOS partition). (This may only be true using the 286 version, and may be affected by your usage. The main point is that you certainly do not take a performance *cut* by using my program.) I am not including most of the COPYING file that comes with stuff from the Free Software Foundation (Richard Stallman, et al.) because I don't know if I'm allowed, but that's what I intend for this software. Specifically, you can *give* away as many copies of this software as you like. You can charge a *reasonable* handling fee. You can even incorporate parts of it into other projects, as long as you distribute at least the source you got from pdisk. I don't want money or contributions, I want plaudits. I hope this software is helpful to you. When you find the inevitable bug (there are *none* in the driver, but I don't absolutely swear for the partitioning program), please try to fix it yourself and let me know the solution. Failing that, drop me a line describing the situation exactly, especially including DOS version and all hardware, including fixed disk and controller type. I don;t promise to do anything about it, but I might. One thing I recommend from experience: my boot code will only work on some IBM compatibles. It is best to use the manafacturer's (or generic) MSDOS fdisk to set up the initial partition, then use "format c: /s" to set up your bootable DOS partition. If you can get this working right with pdisk, that would be nice. have fun. Scott E.
