- Short: Mathieeesingbas.library FPU patch 1.0
- Author: Jess Sosnoski (at the below address!!!)
- Uploader: starblaz@postoffice.ptd.net
- Version: 1.0beta
- Type: util/boot
- Requires: kick 2.04+, an 020+, and a 68881/2 FPU.
-
- Long:
-
- MSBpatch 1.0beta © 1997 Jess Sosnoski
-
- DESCRIPTION:
- -----------
- This is a program that patches some functions of the mathieeesingbas.library
- to use 68881/2 instructions, thus squeezing out a tad more speed.
- (at worst...it should run at the same speed as before)
-
- It also fixes that nasty bug with 040/060 cpu's on certain kickstart versions.
- (I think...someone with an 040/060 please test this!)
-
- This is also the second speedup patch I ever attempted to write! :)
-
- DISCLAIMER:
- ----------
- Use this program at your own risk!
- I assume no responsibility or liability for problem(s) and/or damage(s)
- that occur by the use, modification, and/or existence of this product,
- and/or its parts in any form.
-
- But if it don't work right, or slows things down, don't be afraid
- to send me email...or even send some email if it makes your system
- outprocess a cray (yeah, right)
-
-
- INSTALLATION:
- ------------
- Copy it to your c: directory or wherever you like.
- You can add the line run <>NIL: msbpatch to your startup-sequence, or
- user-startup. You can give it an icon and put it in WBstartup.
- You can basically put it anywhere :)
- (I have mine a little after setpatch in my startup-sequence)
-
- USAGE:
- -----
- run <>NIL: msbpatch
-
- OUTPUT:
- ------
- None...as I didn't feel like figuring out how to to text output
- in assembly.
- Although, if you don't have the right versions of the required libraries,
- it will exit with a returncode of 20.
-
- REMOVAL:
- -------
- sorry....once it's in...it stays in!
- (didn't I hear Al Bundy say that to Peg once...hmmm....)
-
- CAVEATS:
- -------
- This patch is experimental/beta, so, don't expect any miracles.
-
- Opens mathieeesingbas.library, and never closes it.
-
- NO SPEEDTEST PROGRAM (yet)
-
- VERY VERY FEW programs use mathieeesingbas.library.
- I have one program that will use it, and it's THOR software's
- DMandel program. It showed *slight* speed increases.
-
- There exists a 68881 card for 68000 owners, but, as I found out via
- email, does not access the FPU in the same way that an 020+ would.
- I did not include any special code to support this, so it is likely that
- this patch may not do anything at all on that type of setup.
- (Although, if someone would like to let me know if it does...email me!)
-
- NOTES:
- -----
- mathieeesingbas.library is in your Kickstart ROM...you won't find it in libs.
-
- HISTORY:
- -------
- 1.0b First Release
-
- FUTURE:
- ------
- Make this doc file a bit more presentable, and maybe leave it as plain
- text without Amigaguide OR HTML just for kicks.
- Write a more accurate test program, and maybe include it in the archive.
-
- Make a msbtest speedtest program. (in assembly)
-
- Make the patch exit, instead of hanging around.
-
- One word: APATCH (if this patch turns out to work as I'd like it to)
-
- THANKS TO:
- ---------
- Adam "DC1" Polosnik for ideas, help with sourcecode, and APATCH!
-
- Dave "Termy" Jones, for help, ideas and StreamLineOS 2!
-
- Everyone who sent me emails, praise, and complaints....your input
- was greatly appreciated!!!!
-
- BUGS:
- ----
- Hmmm...what would Tom say, ohyeah, um....possibly.
