ERD Commander 6.0 and higher work with ISO mapping:
LABEL erd60
MENU LABEL ^1. ERD Commander 6.0
LINUX /boot/syslinux/memdisk
INITRD /boot/images/erd50.iso
APPEND iso raw

For ERD Commander 5.0, you can try this workaround:

Use the following to boot the image with MEMDISK and Syslinux instead of
grub4dos:
LABEL erd50
MENU LABEL ^2. ERD Commander 5.0
LINUX /boot/syslinux/memdisk
INITRD /boot/images/erd50.dsk
APPEND raw
