... README.1ST ........................... TMi0SDGL(tm) Companion Document ...
Document no.: T-0018.94.95M01.04
*** A T T E N T I O N ***
Please read this document before you proceed with the rest of the library.
Throughout this document
"this code" and "the code" ≡ "TMi0SDGL(tm) Version 1.15 dated 27/02/95".
How to contact author if you found a bug or have any questions/suggestions
about TMi0SDGL.
I can be reached at
2:5028/52.6@fidonet aka 2:5028/51.10@fidonet (Vladimir Zakharychev)
or
xor@cnit.uniyar.ac.ru (internet, ask to forward message to me).
For phone and paper mail address see the CPUTYPE.DOC file.
New features that haven't been tested yet.
TMi0SDGL 1.15 has one new feature that haven't been tested on all systems yet:
AMD Am386 detection. It uses the fact that on Intel's 386s LOCK prefix
doesn't function as documented with some instructions (partially, NOP).
As the documentation says, LOCK NOP sequence should generate an "invalid
opcode" exception while it actually doesn't. AMD's CPUs function properly in
this case. This "bug" was reported by several people found it on several
Intel's 386s. BUT I cannot guarantee that ALL Intel's 386s function this
way. This must be proved by more extensive testing. Because I can't perform
it by myself, I leave it up to you.
DPMI compatibility issues.
This code is fully DPMI compatible. Although only Borland Pascal 7 users
can use this code in protected mode programs without any handwork. Because
of many differences in different C/C++ compilers' protected mode memory
model definitions I do not provide MAKE script for making protected mode
applications using TMi0SDGL with C/C++. You should build protected mode
library manually:
1. compile CPU_HL.ASM and CPUSPEED.ASM with __DPMI__ define and add .OBJes
to library you will use with protected mode application (CPUTYPEX.LIB, for
example);
2. compile SMM.ASM and P5INFO.ASM and add them to the same library;
3. compile CPUTYPE.C with corresponding memory model (DOSX, etc.) and add
.OBJ to the library.
Now you should be able to build protected mode applications using TMi0SDGL
with your C/C++ compiler.
For those having problems with the code in certain environments.
This code haven't been extensively tested on all CPUs it theoretically should
recognize. I performed extensive tests only on systems available to me which
include:
1. AMD Am386DX-40/Intel 80387DX
running MS-DOS 5.0, QEMM 7.04 + DESQview 2.63, Windows 3.11
2. Intel i486DX2-66
running MS-DOS 6.2, QEMM 7.04, Personal NW, Stacker 4.0,
Windows 3.10 Russian
3. GenuineIntel i486SX-40/None - new generation (supporting CPUID)
running MS-DOS 6.2, QEMM 7.01, Windows 3.10
4. Intel 80286-10/Sun SPARCStation 1+ emulating 80286
5. Intel 80386SX-25/Intel 80387SX
running MS-DOS 6.2/MemMaker, Windows 3.10 Russian
6. AMD Am386DX-40/Cyrix Cx87SLC
running Novell DOS 7, Personal NW, Windows 3.10
7. Intel i486DX-50
running MS-DOS 6.2, Windows for Workgroups 3.11
8. Intel Pentium-S/60
running MS-DOS 6.2, Windows for Workgroups 3.11
9. Cyrix Cx486DX-40
running MS-DOS 5.0, QEMM 7.5, Windows 3.11
or OS/2 V3
10. GenuineIntel i486DX-33 - new generation (supporting CPUID)
running MS-DOS 6.0/MemMaker, Windows 3.10
On all listed systems the code appeared to work fine giving correct results
under all listed environments except [1,6] when running Soft-ICE 2.62 -
incorrectly stated that CPU is 386SX - and [9] - FPU was identified as Cx3C87
while it is actually internal. I cannot guarantee that the code will run o.k.
on systems with other configurations/operating environments, though I hope it
will. Please don't bomb me with letters like "wow! this thingie crashes my PC
with such and such CPU/FPU under such and such env." - you got full sources,
and you should know how to use a debugger if you know how to program, so try
to find out the origin of your problem on YOUR system (and maybe a workaround)
before reporting it.
Thanx for yer attention. Now you can proceed with the rest of the library. See
HISTORY.DOC for modification history and CPUTYPE.DOC for license agreement and
contact info.
