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.
