PSIRD is simple to use and, in some cases, a lot better than either the Orion Microsystems RD.COM or ICD's RD.COM. This RAMdisk handler provides a fully sectored RAMdisk, meaning you can even use a sector editor on it! As far as we know, it will work on the following memory types:¢¢Stock 130XE¢Peterson 320K, 576K and 1088K upgrades.¢RAMbo 256k.¢RAMbo 512k upgrade.¢Newell 256K (800XL/1200XL)¢Newell 1088K¢(Compatibility with Newell 4-meg upgrade not tested.)¢¢Not compatible with ICD RD.COM or Orion Microsystems RD.COM (bank selection structure is different. Fully compatible with AtariWriter-80 (RD.COM isn't).¢¢DOS Compatibility: The PSIRD utility only works with the disk-based version 3.2d of ICD's SpartaDOS. It's also compatible with the CSS US+ modified version of SpartaDOS (3.2z).¢¢¢¢**** USING THE PSI RAMDISK HANDLER ****¢¢COMMAND LINE SYNTAX¢¢Command:¢¢RD Dn: [/S=nn] [/E=nn] [/X=nnnn] [/F]¢¢Where:¢¢Dn: n stands for the RAMdisk drive¢ number. THIS PARAMETER IS ¢ NECESSARY FOR OPERATION!¢¢/S=nn is for the starting BANK (a 16k¢ section of memory) where you¢ would like your RAMdisk to¢ start.¢¢ Example:¢ RD D2: /S=47 /F¢ Means "Load RAMdisk handler,¢ using bank #47 for¢ the STARTING bank and¢ use memory all the way¢ to the last bank. Also,¢ format the RAMdisk."¢¢/E=nn is for the ending bank where¢ you would like your RAMdisk to¢ end.¢¢ Examples:¢ RD D2: /S=2 /E=13 /F¢ Means "Load RAMdisk handler,¢ using bank #2 as the¢ start, and using ALL the¢ memory all the way up to¢ bank #13, the ENDING¢ bank, and then, format¢ the RAMdisk."¢¢WARNING! /S and /E should only be used¢ by users with a REAL grasp of¢ Atari Extended Memory!!¢¢/X=nnnn is for logically reserving¢ the banks of memory that¢ would be considered part of¢ the ORIGINAL 130XE extended¢ RAM. Each of the four¢ switches in this parameter¢ can be one of two values as¢ follows:¢¢ 0 = Place bank in RAMdisk.¢ 1 = Place bank BACK in XE¢ extended RAM.¢¢ EXAMPLE: If you own, say, BASIC¢ XE and use our fine¢ RAMdisk handler, you¢ must pass the /X=1111¢ to the RAMdisk so as¢ to allow that stingy¢ BASIC XE cart to have¢ ALL the memory it¢ requires (!).¢¢¢¢/F FORMAT RAMdisk! If you do not¢ include this parameter, the¢ RAMdisk will not be formatted,¢ just installed. Which means:¢ A) If you have just turned on¢ the computer, use the /F to¢ format the RAMdisk for use.¢ B) If you HAD a RAMdisk installed¢ and you cold-started the ¢ computer, don't pass a /F if¢ you wish to have your RAMdisk¢ restored to its former setup,¢ but DO include its starting¢ and ending banks parameter,¢ if necessary.¢¢Starting the RAMdisk without ANY parameters, (except of course, Dn:, which is necessary for operation) creates the largest RAMdisk supported by your system.¢¢Also included is a file called RDF.COM to be used if you have either forgotten to format the RAMdisk or would like to "wipe the slate clean", so to speak. The command syntax is:¢¢RDF Dn: /B=nn¢¢Where:¢¢Dn: is the RAMdisk drive number, n.¢¢/B=nn nn is the max bank # given to¢ you by the RAMdisk program when¢ you ran it.¢¢YOU MUST INCLUDE BOTH OF THESE PARAMETERS FOR THE PROGRAM TO OPERATE! ALSO, THIS PROGRAM IS FOR PSI-RAMdisk ONLY! UNFORSEEN THINGS WILL HAPPEN IF YOU TRY TO USE IT ON A PHYSICAL DRIVE!! ¢¢Thanx and enjoy!¢¢If you find any bugs in this program please report them to PSI Labs at our CompuServe address: 71451,300 (Internet: 71451.300@compuserve.com).¢¢PSI Labs would like to thank Bob Puff for his excellent technical assistance and Don LeBow for his intestinal fortitude as we used him as the RAMbo guinea pig!¢¢
