Feb 0534PPM Laser Printer User Guide 8-13Using the Hard Disk Option and User Flash DIMM ModuleDevice Parameter SetsWhen installed, a device parameter set will be supported for either or both FLASH SIMM and harddisk options. The parameter sets can be referenced using the device names %flash% or %disk0%.Each parameter set will include the following parameters:- LogicalSize- Writeable- BlockSize- Searchable- SearchOrder- Type- Mounted- HasNames- PhysicalSize- InitializeAction- Free- RemovableWarmstart.ps and Sys/Start FilesWhen either or both the FLASH SIMM or hard disk options are installed, there are two featureswhich provide support for automatic execution of a PostScript program during power-on initializa-tion.The first feature is the warmstart.ps file. Each time the printer is powered on, either or both optionalstorage devices will be checked for a file named warmstart.ps. If this file is found, it will be read andparsed by the PostScript interpreter. It is up to the PostScript programmer to create the content ofthis file and get the file onto the storage device using the PostScript device and file operators.The second feature is the Sys/Start file. If either or both of the optional storage devices areinstalled, an additional parameter will be supported in the System Parameter set. This parameter isan integer parameter called StartupMode and is set to 1 by default.NOTE: This parameter can be read or written using the dosysstart and setdosysstart operators.Each time the printer is powered on, if the StartupMode parameter is set to 1, either or both theoptional storage devices will be searched for a file called Sys/Start, a file named Start in a path calledSys. If this file is found, it will be read and parsed by the PostScript interpreter. Again, it is up to thePostScript programmer to create the content of this file and get the file onto the storage deviceusing the PostScript device and file operators.
