windows2经典微软老系统WINDOWS2.03(程序员必读)

================================================================================ MICROSOFT WINDOWS VERSION 2.0 ================================================================================ DOCUMENTATION CORRECTION PIF Editor ---------- Page 182, "Microsoft Windows User's Guide" The manual says the PIF Editor, PIFEDIT.EXE, may be located in the PIF directory, a subdirectory of the main Windows directory. Actually, it is in the main Windows directory. Page 228, "Microsoft Windows User's Guide" The manual says that if "you don't specify an amount of memory, SMARTDrive will receive 256K (the default size)." This is true if you are using extended memory. However, if you are using expanded memory for SMARTDrive, then the default is all of available expanded memory. ADDITIONAL FEATURES Minimize MS-DOS Executive ------------------------- You can automatically reduce the MS-DOS Executive to an icon each time you run an application. This frees up memory and reduces screen clutter. 1. Select the MS-DOS Executive File Run command. A dialog box is displayed. 2. Turn on the check box option called Minimize MS-DOS Executive; then choose the OK button or press the ENTER key. Once you turn on this option, it remains in effect until you turn it off. Spooler will Terminate After Printing is Completed -------------------------------------------------- A feature has been added to the Spooler. If the Spooler is running as an icon, Spooler will terminate (and free up the memory it was using) when printing is finished. If Spooler is running as a window, it will not terminate automatically. NOTES ON EARLIER VERSIONS OF WINDOWS Following are notes of interest if you have used earlier versions of Windows. Using Applications Designed for Earlier Windows Versions -------------------------------------------------------- Windows applications, such as Aldus Pagemaker 1.0A, often include versions of the Windows files SPOOLER.EXE, CONTROL.EXE, and CLIPBOARD.EXE as well as instructions to use these file versions rather than the ones supplied with Windows. You should NOT use these file versions with Windows 2.0. Instead use the Windows 2.0 versions of SPOOLER.EXE, CONTROL.EXE and CLIPBOARD.EXE. This contradicts the instructions included with your application; however, these instructions apply to using the application with earlier versions of Windows, not to using the application with Windows 2.0. New Font File Format -------------------- Some applications designed for use with Windows include font files (files with a .FON extension). For example, Aldus Pagemaker 1.0A includes several font files. Font files designed for use with earlier versions of Windows will not work correctly with Windows 2.0. Included with Windows 2.0 is a program, NEWFON.EXE, that converts your old font files to the new Windows 2.0 format. Here's how to create the new font files: 1. Change directories to the disk drive and directory in which the old font file(s) is located. 2. Create a backup copy of the old font file(s). You do this by typing the following command: COPY *.FON *.BAK 3. Place the "Utilities Disk" in drive A: 4. Start the Newfon program from the A: disk drive. The form of the Newfon command is the following: A:NEWFON [old-font-filename] For example, to create a new PageMaker font file, PMFONTE.FON, you would type: A:NEWFON PMFONTE.FON NOTE: You may also specify a new font file name. The form of the Newfon command for doing this is the following: A:NEWFON [old-font-filename] [new-font-filename] WARNING: You will lose the old font file if you do not make a backup copy. Be certain to backup your old font files. Using Windows 2.0 Paint Files with Applications Designed for Windows 1.0 ------------------------------------------------------------------------ The Windows 2.0 Paint file format differs from that of earlier versions of Paint. Thus applications designed to read Windows 1.0 Paint files can no longer do so. To work around this problem, either use Copy and Paste to move images from Windows 2.0 Paint into those applications designed to read Windows 1.0 Paint files, or use CVTPAINT.EXE to convert 2.0 Paint files into 1.0 Paint files. Paint version 2.0 can read Paint files having the version 1.0 format. CHANGING SETTINGS IN THE CONFIG.SYS FILE The following notes relate to changing command lines in the CONFIG.SYS file. Using SMARTDrive ---------------- Appendix C, "Speeding Up Windows with SMARTDrive" in the Windows User's Guide contains detailed instructions on installing the disk-caching program SMARTDrive provided with Windows 2.0. The following is updated information on adding SMARTDRV.SYS to your CONFIG.SYS file: - Set the buffers= command line to 10. Setting buffers= to higher values uses memory without additional performance benefits; setting it to a lower value reduces performance benefits. - Put the "device=smartdrv.sys" command line after the "device=" command line for any expanded memory manager you may be using (i.e. emm.sys, remm.sys, ps2emm.sys, etc.). - If you have a Compaq Deskpro and ENHDISK.SYS is listed in your CONFIG.SYS file, and you wish to use SMARTDrive, you must list the SMARTDRV.SYS command line after ENHDISK.SYS. - If you intend to use expanded memory for SMARTDrive, be sure to use the /A flag. Using RAMDrive -------------- In general, SMARTDrive gives better overall performance than RAMDrive. One exception is output performance for frequently written files. We recommend that you use SMARTDrive; however, a new version of RAMDrive is included with Windows 2.0. This version performs significantly better than older versions and is the ONLY version that works with Windows 2.0. For detailed documentation on RAMDrive, see RAMDRIVE.TXT located on your Utilities Disk. Using EGA.SYS with an EGA Display Adapter ----------------------------------------- If your display adapter is an EGA (Enhanced Graphics Adapter), you can improve the quality of standard applications by using the device driver file EGA.SYS included on the Utilities Disk. Here's what to do: 1. Copy EGA.SYS from the Utilities Disk to your hard disk. 2. Add a line of the following form to your CONFIG.SYS file: device=[drive:][path]EGA.SYS If you have a mouse installed on your computer, be sure to add the EGA.SYS line before the MOUSE.SYS line. Adding the EGA.SYS device driver is optional; it will enhance the performance of standard applications, but it is not required. NOTES ON USING EXPANDED MEMORY Windows 2.0 can utilize any expanded memory board which implements the LIM 4.0 expanded memory specification in its memory management software. To determine if your expanded memory board implements LIM 4.0, see your board's documentation or contact the manufacturer. Windows 2.0 contains software supporting the AST RAMpage, the IBM Personal System/2 Expanded Memory Option, and the Intel Above Board. This software is located in three files, REMM.SYS, PS2EMM.SYS, and EMM.SYS located on the Utilities Disk. The software for the AST RAMpage is named REMM.SYS. For detailed instructions on how to install REMM.SYS, see the file REMM.TXT on the Utilities Disk. The software for the IBM Personal System/2 Expanded Memory Option is named PS2EMM.SYS. For detailed instructions on how to install PS2EMM.SYS, see the file PS2EMM.TXT on the Utilities Disk. The software for the INTEL Above Board is named EMM.SYS. For detailed instructions on how to install EMM.SYS, see the file EMM.TXT on the Utilities Disk. The performance of expanded memory boards is enhanced by disabling some of your computer's main memory, and replacing that memory with some of your expan
