I'm currently using ISOLINUX to create a bootable MS-DOS 6.22 image in the RAM.

This is working pretty well! I can stuff the folders CDROOT and isolinux in this setup and then create a new ISO with an included BATCH file, which I then use on a bootable USB flash drive to be booted from.

The contents of CDROOT are marked as A: in the running DOS, contents of isolinux are then mounted on D:.

I tried to access those RAMDisks with simple MS-DOS commands like MKDIR or DEL. On isolinux this is perfectly possible.

But I don't have any write access on my mounted CDROOT. You may guess it, but I need write access there.

How do I enable the mounted ISO as writeable in the mounted RAMDisk?

CDROOT is essentially a RO image; some of its contents is initially moved to a RW ram disk (D:); if you need to edit content from CDROOT you must move it first to a RW area. Please consider any edit is not persistent.
