- 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.

- 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.
