emTeX and FreeDOS - some info

I made some testings.


emTeX INSTALL prog proceeds in 2 steps:
STEP 1. copying required files, patching emTeX BAT
files, updating autoexec.bat & config.sys
STEP 2. after rebooting, generating required formats
(plain, LaTeX), etc.


Platform: intel 486 DX 33, 8MB RAM, CD-ROM:4x (TORISAN)


Fast note to users without coprocessor (i.e. 486SX):
When Step 1 is done, and BEFORE Step 2 download and unpack
full emxrt.zip, because you will need coprocessor emulator:
(\emx\bin\emxfpemu). It's invoked by emx when needed.
emxrt.zip is available at: i.e:
ftp.lucky.net/pub/Os2/emx09d/




emTeX INSTALL: 0.2e, 09-Jul-1998
Source: TeXLive 4, CD, March 1999


Type of installation: full, default answers,
font: ljh (HP LJ, DJ: 600dpi),
install emx: YES
(emx is required to run tex386 - a version allowing
to typeset the largest *.TEX files)


1. FD Beta 8 Official Release
=============================


FreeDOS kernel version 1.1.26a (Build 2026a) [Apr 05 2002 18:13:06]
Kernel compability 5.0 - TURBOC


FreeCom version 0.83 Beta 32 [Dec 03 2001]


SHSUCDX Version 1.4b, October 2000


Results:
--------
1. Installing from HDD - no problems
2. Installing from CD - no problems


Info:
-----
Running tex386 that invokes emx requires to have
"device=himem.exe" in your config.sys.
Emx requires XMS-Driver to identify itself as version 2.06




2. FD Beta 8 with Kernel 2027test
=================================


FreeDOS kernel version 1.1.27 (Build 2027test) [Aug 04 2002 11:32:10]
Kernel compability 5.0 - WATCOMC


FreeCom version 0.83 Beta 40 XMS_Swap [May 11 2002 23:55:25]


SHSUCDX Version 1.4b, October 2000


Results:
--------
1. Installing from HDD
Remove "device=himem.exe", if any, from your config.sys
Otherwise you will get after emTeX INSTALL prog message:
"Installing some files of emxrsx.zip" another message:
c:\emtex\install\install.tmp: string table corrupt
and INSTALL will exit.


XMS support is built (?) into kernel/command.com (??)
- emx will run without additional XMS Driver.


2. Installing from CD
(It doesn't matter if there is or not himem.exe in config.sys)


I can't do it with SHSUCDX Version 1.4b, October 2000.
I get after "Installing some files of emxrsx.zip"
c:\emtex\install\install.tmp: string table corrupt
and INSTALL exits. :(


What may sound interesting, even if SHSUCDX is in memory
(proper line in autoexec.bat, cdrom device in config.sys)
I CAN install emTeX from HDD. I CAN'T do it from CD-ROM.
(CD-ROM itself is OK: fast SYS C: from FD Beta8 Official
Release, and I can install emTeX from CD).




What's more, try to run Dos Navigator 1.51 
(free Norton Commander clone), just after INSTALL exits.
(when failed).
I get message in inf loop:
"Invalid Opcode at 013F 0629 0046 0000 0000 0001
0000 0000 0000 0000 0000 0000 0000"


Address is always the same.


After 2-3 min. inf loop is:
"Invalid Opcode at"




Ctrl-Alt-Del works. Break works, too.
