Using PC Cards (continued)
Problem
You are trying to format a flash PC
card with the MCFORMAT utility
and you see the message "You must
erase G: before creating a new
partition."
After you load your Novell network
software, you are using a network PC
card and run an application that does
not work properly after making a
system call.

Solution
If a flash card has been formatted before, you must first erase
the card before you can format it. Use the MCFORMAT utility
and select Option 3 from the MCFORMAT main menu to erase
a flash card.
If you erase the flash card and still see this message when you
try to format the card or the card will not format, check the
JANUS 2050 CONFIG.SYS file. Make sure you have the flash
card drivers installed. Once the flash card drivers are active in
the CONFIG.SYS file, try erasing the flash card. Then format the
card.
If you notice a problem with an application trying to execute a
system call, your Novell network software may have modified
the COMSPEC environment variable to add a drive specifier to
the path. DOS uses the COMSPEC environment variable to find
the COMMAND.COM file, and COMMAND.COM must be
loaded in order for DOS to execute a system command. The
JANUS 2050 uses ROM DOS 5.0, which expects COMSPEC to
be set to:
comspec=command
To eliminate this problem, you must run a special utility named
INITENV.EXE before you log in your JANUS 2050 to a NetWare
server. Use the INITENV.EXE application on the JANUS 2050
drive C and create a login batch file similar to the following
generic example:
@echo off
c:\initenv
f:\login %1 %2
set comspec=command
Use the new login file instead of your Novell login file when
you log in your JANUS 2050 to the server. If you do not run
INITENV.EXE before you log in, your DOS environment table
will be corrupted and it may cause your JANUS application to
fail. You can set COMSPEC correctly to fix part of the problem,
however you need to reboot the JANUS 2050 to clear embedded
garbage characters from the environment table.
To check the COMSPEC environment variable, type set and
press e . All the environment variables are displayed. If
COMSPEC is set to anything other than COMMAND, it has
been changed by the login process.
