I'm setting up my old 486 with a bunch of DOS games. I'm having a problem where ISO images mounted with SHSUCD 3.9 are not readable by 4DOS.COM from 4DOS 8.00. 4DOS is able to read my physical CD-ROM drive though. But DIR on a mounted ISO just shows the volume label and nothing else (no files, nothing about free space). If I switch back to COMMAND.COM (from MS-DOS 7.10) it works.

Here are the relevant lines I use:

config.sys

1DEVICEHIGH=C:\DOS\VIDE-CDD.SYS /D:VIDE-CDD
2rem SHELL=COMMAND.COM /P /E:640
3SHELL=C:\4DOS\4DOS.COM C:\4DOS /P

autoexec.bat

1LH C:\SHSUCD\SHSUCDX /D:*SHSU-CDH,D /D:VIDE-CDD,E

I'm mounting the ISOs like this:

1c:\shsucd\shsucdhd /f:c:\mypath\myiso.iso
2c:\shsucd\shsucdx /d:shsu-cdh

... and unmounting like this:

1c:\shsucd\shsucdx /d1
2c:\shsucd\shsucdhd /u

So my question is if anybody knows a way to make this work using 4DOS still? Am I doing something wrong above? It's too bad, I really liked 4DOS (new experience for me), but I guess I'll just have to live without it. 🙁
