----------------------------------------------------------------------- *** NOTE: See LICENSE.DOC to find out how to access ALL 384k of memory! ----------------------------------------------------------------------- The EXTENDER software consists of the following 14 distribution files. Feel free to upload this package to any bulletin board, but please be sure all 14 original (unmodified) distribution files are included in the upload. README.1ST This text file. LICENSE.DOC A text file explaining how to license your copy of EXTENDER and obtain your own personal access key that permits access to all 384k of high memory. Without an access key, you will be able to try out all the features of EXTENDER, but your access will be restricted to a maximum of 32k of high DOS memory and 32k of high Bank-Switch memory. WARRANTY.DOC A text file explaining the terms and conditions of the EXTENDER warranty. EXTENDER.DOC A text file explaining how to use EXTENDER. LICENSE.EXE This program modifies the file EXTENDER.SYS to install your name and personal access key. EXTENDER.SYS This device driver must be loaded before using any of the other software supplied with EXTENDER. It determines what high memory space can be used and initializes it. If possible, it will also copy any Bios ROM it finds to Shadow RAM for faster execution. When finished with its initialization process, EXTENDER relocates the resident portion of itself to high memory, leaving only 32 bytes of itself in DOS memory. HIGHDRVR.SYS This device driver is used to load other device drivers into high memory. Each use of HIGHDRVR.SYS leaves only 48 bytes of itself in conventional memory in order to connect the device driver (that was loaded into high memory) to the operating system. HIGHDISK.SYS This device driver implements a RAM disk in high memory, using bank-switching techniques to access the memory behind the Bios ROM or any installed adapter. (The driver itself may be loaded into high memory by using HIGHDRVR.SYS.) HIGHTSR.EXE This program is used to load TSR's into high memory. Once the TSR has been loaded, this program completely removes itself from memory. HIGHMARK.EXE Used to mark TSR's so that they may be removed from high memory at a later time. The mark is placed in the bank-switch portion of high memory where it has no effect on the amount of memory available for TSR's and device drivers. HIGHUNDO.EXE Used to remove TSR's (and the associated mark) that have been marked with HIGHMARK. HIGHMEM.EXE Displays a map of high memory usage. COLS.40,80 Text files to be used to verify that ANSI.SYS has been installed and is operating properly. --------------------- End of file README.1ST ---------------------
