Unzip Version 6.0 hangs when booting to a commandline

However, when I called the "unzip.exe" version 6.00 that is installed via YUM, the bootup commandline would hang and the unzip help screen would never show up.
When I instead used the "unzip.exe" version 5.52 that is still in my ECS\BIN subdirectory, it would properly work without such a problem. I am sure it is not a DLL loading problem as the LIBPATH setting is the same as for the regular boot, but of course, the newer UNZIP uses different DLLs (gcc, libcn0) than the older version (which directly uses the OS/2 API).

Anyone knows what's going on or how to fix that ?

When using the commandline boot with Alt+F1  --> F2, the system boots using ?:\os2\boot\config.x instead of ?:\config.sys .
I would compare config.x and config.sys .

Is there an entry in \popuplog.os2 ?
Unfortunately it is not possible to use PMDLL when booted to a commandline, and I don't know about an existing VIO-equivalent.

I just wanted to test it too. Indeed on the VM (ArcaOS 5.0.7 ), the unzip.exe hangs when you boot with Alt+F1 and F2 for command line.
(It also fails here)

I don't recall which was the config.sys for that F2 boot. config.1 or config.x ?

For what I see on the F2 boot the %LIBPATH% is not recognized, but the config files looks fine. Is there any elegant way to see full the enviroment variables on the command line (image LIBPATH_F2.png )?

For a F2-boot ?:\os2\boot\config.x is used (read the description on the line that starts with F2 when you have used Alt+F1).

LIBPATH is not an environment variable (in config.sys there is a line that starts with LIBPATH=..., but not a line that starts with SET LIBPATH=...).
So trying to use %LIBPATH% does not work.

Seeing all environment variables is easy: on a commandline type

SET | more

(or pipe the output of SET to a file: SET > somefile.name)

Dave Yeo:
Also the env command will list all variables. env | less

chkdll32.exe. Not tested if it works from ALT-F1.
