This area contains FX:, a memory disk for RSX11M or RSX11M+ V3.2, V4.0, V4.1, V1.0, V2.0, V2.1 (M or M+ respectively). It allows use of a memory partition as a fast disk, size variable, and is now known to work right. Unlike some earlier efforts, this driver checks the fork queue after every block to avoid blocking fork processing. Thus it won't clog your system the way some such programs will. This program is recommended for system libraries or heavily overlain tasks where the decrease in load time can buy significant system response. No SYSGEN required for use, but you should VMR in a dedicated partition which the driver will detect and use to size the device. Device size should be a multiple of 512 bytes and some of the command files here will create the device as a single directory volume (undocumented INI switch /SDI) to avoid overhead of extra UFDs, and which will allow files on the memory disk to be truly global. You can make it an ordinary files-11 disk as needed, or of course make any other file structure desired or needed, just as for any virtual disk. This program came from F82RSX originally but was fixed up for other versions of RSX and to check fork queue by g. Everhart. It has had a couple of bugs that messed up use with very large (>2 MB) disk partitions fixed.
