Memory Card Explorer for RICOH

Troubleshooting

Title: Required Memory Window (D0000) may not be available.

Environment: Windows 95/98

[OK] : Closes the dialog and MCERICOH does not start.

Cause:

MCERICOH requires a 4kbyte memory window to communicate with the PC card controller. If the default memory window is not available at MCERICOH startup, you receive the above error message. Normally, this means that another system device has already reserved the D0000-D3FFF memory window at Windows startup.

Solution / Workaround:

Reserve a 4kbyte memory window for MCERICOH using the following procedure.

1. Edit Config.sys and System.ini to exclude the next 4k memory window at Windows startup.

Config.sys
DEVICE=C:\WINDOWS\EMM386.EXE RAM X=D400-D7FF
System.ini
[386Enh]
EmmExclude=D400-D7FF

2. Restart Windows.
3. After Windows has restarted, open a Command Prompt and enter the following commands.

C:\WINDOWS> cd \progra~1\memory~1 [Enter]
C:\Program Files\Memory Card Explorer for RICOH> mcericoh /wd4 [Enter]

4. If MCERICOH starts without the "Memory Window may not be available" error message, memory window configuration has finished.
If the same error message appears at the MCERICOH startup, repeat steps 1 through 4 again for the next 4kbyte memory window.

Memory Window	/w option	Memory Window	/w option
D000-D3FF (default)	mcericoh /wd0	E000-E3FF	mcericoh /we0
D400-D7FF	mcericoh /wd4	E400-E7FF	mcericoh /we4
D800-DBFF	mcericoh /wd8	E800-EBFF	mcericoh /we8
DC00-DFFF	mcericoh /wdc	EC00-EFFF	mcericoh /wec

Once you succeeded in starting MCERICOH without this error message, the memory window setting is stored in the mcericoh.ini file. This allows you start MCERICOH just by clicking on the MCERICOH program icon the next time.

If you could not succeed in starting MCERICOH even after trying all of the above settings, your computer hardware does not allow MCERICOH to use a 4kbyte memory window in the memory range D000-EFFF.
You can either give up using MCERICOH with this computer, or try again after changing the computer's hardware configuration.
