INtime 3.1 Software
Loading a user application on an RT node at boot time
To have one or more user applications load at boot time on an RT node, simply add
them to the appropriate RtLoad file after the system applications. For example, to cause
the application MyApp.rta to load with input parameters "base=0x760 irq=5" on an
RT node set up to boot up with a UDP-based NTX interface to its Windows host,
modify the RtLoad.sys file as follows:
• After ntxproxy.rta, add this line:
\myapp.rta "base=0x760 irq=5"
• Set process-level parameters in RtLoad.sys following the switch setting
information described in the next section.
RtLoad.sys file format and switches
First character
The RtLoad.sys file is generated by the INtime Configuration utility, based on user
input. As the RT image boots, it finds the RtLoad file specified in the RtConfig.sys
configuration file and parses its contents to determine which applications to load, and
in what order. Each line (terminated with a LF character) in the file can indicate the
full pathname of an application to load as the RT system initializes. Applications load in
the same order as they appear in the file. The load file has the following per-line format:
Mode Description
; Treat the entire line as a comment.
# Print the rest of the line on the current STDOUT device and wait for a response from
the STDIN device before proceeding to the next line. This is useful when booting from
a floppy device and then pausing to insert the second (or nth) floppy of the set before
proceeding. (Only supported if Logging Mode is set to “Stdout” and Printf/Scanf
console is set to “Local” on the Loader page of the INtime Configuration utility’s
Remote Client Settings tab.
\ Indicates that the following characters before the next space represent an application
program in the root directory of the boot device.
^
Processes the following character as a command to the Loader (Remote INtime Run-
Time Application Loader). Supported command characters include:
E Tells the loader to enlarge the code segment (same as Open Data Segment
in the INtime Loader) for the next application listed for loading in the
RTLOAD.SYS file.
Other Any other character is assumed to be the first letter of the application program
assumed to be in the root directory of the boot device.
