- Hardware Requirements
- ---------------------
-
- - emx requires an 80386 CPU (80386DX, 80386SX, i486)
-
- - emx requires an 80387 coprocessor (or i486 processor) if floating point
- math is to be used under DOS
-
-
- DOS Notes
- ---------
-
- - emx requires DOS 3.0 or later
-
- - emx does not support DPMI
-
- - emx does not support DESQview without VCPI (use QEMM-386 with DESQview)
-
- - If emx doesn't work under DESQview (especially if it displays the
- message `Nonmaskable interrupt (NMI)', either set the protection
- level to 0 or use the WATCHDOG=0 option of QEMM-386.
-
- - emx supports VCPI
-
- - emx supports XMS. Do not use emx with himem.sys 2.06 or earlier.
-
- - emx checks for XMS version number 2.00 or later and for
- XMS driver revision 2.06 or later, as older himem.sys drivers
- don't work correctly. You can override this check by giving
- the -O command line option (for drivers using a different
- revision numbering scheme), but emx may not work with your
- XMS driver, anyway. Actually, emx has not been tested with
- himem.sys 2.05; 2.04 fails, 2.06 works.
-
- - emx supports VDISK.SYS 3.3 and later and most other RAM disk drivers
-
- - emx uses (or tries to use) all available memory, whether
- conventional, extended, or expanded memory. But it does not use
- extended memory AND expanded memory at the same time. If there
- isn't enough memory, emx will swap to disk. The swap file will be
- created in the directory given by the EMXTMP environment variable.
- If EMXTMP is not set, TMP will be used. If both variables are not
- set, the swap file will be created in the root directory of the
- current drive.
-
- - Do not put BREAK=ON in your config.sys file. BREAK=ON causes
- problems with lots of other programs as well.
-
-
- OS/2 Notes
- ----------
-
- - emx requires OS/2 2.0
-
- - emx does not run in DOS mode of OS/2
-
-
- DOS Programs
- ------------
-
- emx.exe DOS extender
-
-
- OS/2 dynamic link libraries
- ---------------------------
-
- emx.dll emx run-time support for OS/2 2.0
- emxio.dll access to hardware ports for emx programs under OS/2 2.0
- emxlibc.dll emx C library
-
- These dynamic link libraries must be in a directory listed by the
- LIBPATH statement of config.sys. Either copy these files to such a
- directory or add to the LIBPATH statement the directory where these
- files have been installed. Note that LIBPATH is not an environment
- variable.
-
- You can't replace a dynamic link library while it is used by any
- program. If you can't install emx.dll, use `pstat /c' to find out
- about programs that use emx.dll.
-
-
- Usage (DOS)
- -----------
-
- Run a bound program by typing its name.
-
- Run an a.out file by typing
-
- emx [options] program [arguments]
-
- emx options (can also be used in EMXOPT):
-
- -c Disable core dumps caused by signals other than SIGKILL
-
- -d Don't use extended memory
-
- -e Don't check for 387 coprocessor. Assume no coprocessor is
- present
-
- -h# Set DOS file handle limit to #. The number # must be between
- 10 and 255. This option is ignored for DOS versions earlier
- than 3.30. This option does not change the emx limit for the
- number of files per process -- that limit is always 40
-
- -m1 Running on Fujitsu FMR70 (not implemented yet)
-
- -m2 Running on NEC PC-98 (not implemented yet)
-
- -m3 Running on Inboard 386/PC
-
- -o Send register dump (of exception) to stdout (instead of CON,
- for redirecting register dump)
-
- -r* Prepend drive letter * to absolute path names. If a path
- name starts with / but does not start with //, /dev/ or
- /pipe/, * followed by a colon will be prepended. If -rd has
- been given, the file name \mydir\abc will be translated to
- d:\mydir\abc. Note: this option can cause unexpected effects
-
- -t Truncate file names to 8.3
-
- -O Override XMS version check
-
- -V Display emx version
-
-
- Options can also be stored in the environment variable EMXOPT. emx
- first examines the options given in EMXOPT, then the options given on
- the command line.
-
-
- Usage (OS/2)
- ------------
-
- Run a bound program by typing its name. If you've got different
- versions of emx.dll, use the latest one. To get the revision number
- of an emx dynamic link library, use emxrev.cmd.
-
- You can use the following options in the EMXOPT environment variable:
-
- -c Disable core dumps caused by signals other than SIGKILL
-
- -h# Set OS/2 file handle limit to #. The number # must be
- between 10 and 255
-
- -r* Prepend drive letter * to absolute path names. If a path
- name starts with / but does not start with //, /dev/ or
- /pipe/, * followed by a colon will be prepended. If -rd has
- been given, the file name \mydir\abc will be translated to
- d:\mydir\abc. Note: this option can cause unexpected effects
-
- -t Truncate file names to 8.3
-
- -E Run debuggee in same session (window) as debugger
-
- If OS/2 says
-
- SYS1804: The system cannot find the file EMX.
-
- when running a program compiled for emx, you haven't correctly set the
- LIBPATH statement of config.sys. See above for details.
-
-
- Environment variables
- ---------------------
-
- INIT used by termcap
- TERM used by termcap
- EMXETC used by termcap
- EMXOPT emx options
- EMXPATH search path for programs
- PATH search path for program (used if EMXPATH fails)
- TERMCAP used by termcap
-
-
- Environment variables (DOS)
- ---------------------------
-
- EMX path name of emx.exe, used by programs which are bound
- with emxl.exe (the emx loader) instead of emx.exe.
- Set EMX to speed up loading of emx.exe or to load a
- specific version of emx.exe
-
- EMXTMP directory for swap file
-
- TMP used if EMXTMP is not set
-
- If the program name doesn't contain a drive and directory name, the
- current directory will be searched first, then all directories listed
- in EMXPATH and PATH.
-
- If the program name contains a drive or directory name, no search
- will be done, only the given path name is tried.
-
-
- Messages (DOS)
- --------------
-
- Abnormal program termination
-
- The program received the SIGABRT signal. The abort() function was
- called or SIGABRT was raised.
-
- Cannot create swap file
-
- The swap file could not be created. Remedy: make sure the swap
- file can be created in the directory given by the EMXTMP (or TMP)
- environment variable. If EMXTMP and TMP are not set, emx will
- create the swap file in the root directory of the current drive.
-
- Cannot enable A20
-
- emx tried to enable address line A20 and failed. Remedy: contact
- the author.
-
- Cannot enable A20 via XMS
-
- emx tried to enable address line A20 by calling the XMS driver.
- Unfortunately, A20 couldn't be enabled. Remedy: unknown.
-
- Cannot open program file
-
- The program file given on the emx command line could not be found
- or opened. Remedy: type the correct file name. (This should not
- happen with bound programs.)
-
- Cannot read program file
-
- An error occured while reading the program file. Remedy: make
- sure the program file given on the emx command line is valid (this
- does not apply to bound programs). Maybe some other program
- accesses that file.
-
- DPMI not supported
-
- The current version of emx cannot use DPMI. Maybe some future
- version will do. Remedy: end the DPMI server (Windows 3.0).
-
- Exception ...
-
- The program run by emx did something illegal. Remedy: report to
- the supplier of the program.
-
- Illegal syscall function
- Illegal viocall function
-
- The program run by emx has called an invalid system function.
- Remedy: report to the supplier of the program.
-
- Invalid arguments for DOS function xx
-
- The program run by emx has used invalid arguments for a system
- function. Remedy: report to the supplier of the program.
-
- Invalid program file
-
- The program file given on the emx command line (or bound to emx)
- is corrupt. Remedy: reload the program from diskette. If this
- doesn't help you should contact the supplier of the program.
-
- Invalid special function code: xx
-
- The program run by emx has called an invalid system function.
- Remedy: report to the supplier of the program.
-
- Linear address space exhausted
-
- The program run by emx uses far too much memory. remedy: complain
- to the author.
-
- Nonmaskable interrupt (NMI) at xxxx:yyyyyyyy
-
- A nonmaskable interrupt occured. Maybe this is due to a memory
- error. Remedy: if you're using DESQview, either set the
- protection level to 0 or use the WATCHDOG=0 option of QEMM-386.
- Otherwise, run a program for testing memory.
-
- Out of memory
- Out of memory (RM)
-
- There isn't enough memory for running emx. Remedy: remove some
- drivers and/or resident programs. Or add memory to your machine.
-
- Out of stacks
-
- emx run out of local stacks. Remedy: complain to the author.
-
- Out of memory or swap space
- Out of swap space
-
- emx cannot write to the swap file because the disk is full.
- Remedy: make sure there is enough space on the drive used for the
- swap file. Use the EMXTMP (or TMP) environment variable to tell
- emx where to create the swap file. If neither EMXTMP nor TMP is
- set, emx will create the swap file in the root directory of the
- current drive.
-
- Process terminated by SIGINT
- Process terminated by SIGBREAK
-
- You've stopped the program by hitting Ctrl-C or Ctrl-Break.
-
- Program aborted
-
- You've aborted the program by answering `Abort' after a critical
- error had occured.
-
- Swap file I/O error
-
- emx couldn't read or write the swap file.
-
- This program does not run in DOS mode of OS/2
-
- DOS emulation of OS/2 doesn't support emx. Remedy: boot DOS or
- use OS/2 2.0.
-
- This program requires an 80386 CPU
-
- You need an 80386DX, 80386SX, or i486 CPU for running emx.
- Remedy: get another computer.
-
- This program requires DOS 3.0 or later
-
- If emx is bound with an application program into one executable,
- DOS 3.0 or later is required for execution.
-
- Too many processes
-
- emx supports up to 4 processes. You've tried to start 5 or more
- processes.
-
- Unexpected interrupt
-
- This cannot happen. Remedy: report to the author.
-
- Unsupported VDISK.SYS version
-
- emx doesn't support the VDISK.SYS device driver you're using.
- Remedy: remove VDISK.SYS or use a different version. emx should
- work with VDISK.SYS 3.3 or later.
-
- Unsupported XMS version
-
- emx requires himem.sys 2.06 or later (older versions are too
- buggy). Remedy: get a newer himem.sys. If you're not using
- himem.sys, use the -O option of emx and tell the author whether
- this works or not.
-
- Unusable interrupt vector mappings set by VCPI server
-
- The configuration of the VCPI server (EMS driver) is illegal.
- Remedy: read the manual of the EMS driver.
-
- Virtual mode not supported without VCPI
-
- A VCPI server is required to run emx if the CPU is in virtual
- mode. You'll get this message if you're using an EMS driver (EMS
- emulator) which doesn't support VCPI or if you've disabled EMS.
- Remedy: remove the EMS driver, use an EMS driver which supports
- VCPI or enable EMS if it has been disabled (for instance, remove
- the NOEMS keyword from the command line of the EMS driver).
-
- Wrong emx version
-
- The version of emx.exe does not match the version the program was
- compiled for. Remedy: use the copy of emx.exe that comes with the
- program. If you're using different programs which need different
- versions of emx.exe, use the EMX environment variable to set the
- path name of the correct version of emx.exe before running a
- program which requires a version different from the default
- emx.exe. You can also use the emxbind utility of the emx package
- to put the correct version of emx.exe into the executable files.
-
-
- Obtaining the complete emx package
- ----------------------------------
