Note that if your monitor is Plug and Play compliant (i.e. supports VESA DDC) and you wish to use the DDC timings, you must go with the Windows 95 monitor selection. Once all the files are installed, a Matrox Wizard will guide you through the steps to take in order to change the Windows 95 display adapter type from MGA to MGA PowerDesk mode.This is done in the Windows 95 Display Properties dialog box. You will have to re-boot at the end of this procedure. After rebooting, you can change your preferred mode by opening the Windows 95 Display Properties dialog box again (right-click on the desktop background), and you will notice a new page called MGA Settings. This is described in detail in the `MGA Settings' section later in this document. Re-installing PowerDesk for Windows 95: If you are re-installing the PowerDesk software, the setup program will detect an earlier installation, and you will be asked if you wish to reset or keep your current settings. If you choose to reset, your schemes, your hotkeys, and your performance preferences will be lost, but you will still reboot with the same Display area and Color Palette as before. Monitor Selection The MGA display driver supports Windows 95 monitors. This means that the monitor that is listed in the Change Display Type dialog box is handled by the MGA display driver, in terms of maximum resolution and refresh rates. The driver supports various video timings ranging from 60Hz to 85Hz, including all standard VESA timings. The MGA display driver will take the timings that best match the frequency ranges reported by Windows 95 for the chosen monitor. However the MGA driver does not recognize Plug and Play (DDC) monitors, so you should not select a DDC monitor because an "unknown monitor" would be assumed. Also, the MGA Settings page will not allow you to select a Display area (resolution) that is higher than supported resolution for your monitor. It is very important that you not leave your Windows 95 monitor as "unknown" (unless you have chosen to use the MGA Monitor Program, described later in this document). It is also important to update the monitor type if you change your monitor. Do this before connecting the new monitor, then reboot right away with the new monitor. This will ensure that you will not boot in an unsupported resolution. MGA Settings The MGA Settings sheet is a property sheet that is added to the Windows 95 Display Properties dialog box when you install our driver. This page supercedes the standard Settings page, whose contents are greyed out (dimmed, and unavailable) when a MGA adapter is present. In addition to the usual settings for the Display area, Color Palette, and Font Size, the MGA Settings page introduces an enhanced Desktop area feature whereby you can create a Desktop area that is larger than the current Display area (you can expand your working area beyond the limits of many monitors). This page also gives you the ability to save multiple configurations as Display Schemes. Additionally, a few Advanced setting pages are available for driver configuration, hotkey setup, and information about your board. On-line help is available exactly as for other Windows 95 sheets, that is: click on the question mark icon in the upper right corner, then click on the item on the sheet that you want help on. Note: The MGA Settings sheet does not implement the "display test" that is performed by the Windows 95 Settings page when changing the resolution. We assume that your monitor is properly selected, so we can save that extra step. Quick Access MGA Quick Access is part of the MGA PowerDesk folder, which is accessible from the Programs flyout on the Start menu. It allows quick access to the following PowerDesk features: PixelTOUCH zoom, PanLOCK, CenterPOPUP, and four pre-defined Display Schemes that are read from the MGA Settings page. You can see a "tool tip" for each button if you leave the mouse cursor over the desired button for a few seconds.

Installation Installing MGA (Windows 95 is already installed): This procedure applies to those installing the MGA adapter on a Windows 95 computer configured for VGA (or other display adapter). Shut down your system and install the MGA card (remove any other VGA card or disable any on-board VGA if you plan to use a single display screen). Start Windows 95. The system will detect that a "MGA Ultima / Impression Display Adapter" was added, and will copy the appropriate software. You will have to restart Windows to complete the Plug'n'Play installation. After rebooting, your display will be 640 x 480 with 256 colors. Upgrade the Plug And Play driver version 1.0 by following the "Upgrading the Windows 95 MGA driver v.1.0" procedure. Installing Windows 95 (MGA is already installed): This procedure applies to those installing Windows 95 on a Windows 3.1 computer already configured with a MGA. Start the Windows 95 Setup program. As part of the installation, a hardware detection process will detect a "MGA Ultima / Impression" board, and the Microsoft MGA driver version 1.0 will be copied to your hard-disk. You will have to restart your computer to complete the Plug And Play installation. After rebooting, your display will be 640 x 480 with 256 colors Upgrade the Plug And Play driver version 1.0 by following the "Upgrading the Windows 95 MGA driver v.1.0" procedure. Upgrading the Windows 95 MGA driver v. 1.0: This procedure applies to those upgrading the Microsoft MGA driver version 1.0. To upgrade the Microsoft MGA driver, insert the Matrox MGA PowerDesk diskette in drive a: and use the Run flyout in the Start menu to run a:Setup.exe. You'll be prompted for a destination directory (C:\Matrox\MGA is the default), and asked if you want to install the Quick Access and MGA Monitor applications. The setup program will check to see if a Matrox mga.inf monitor file exists on your system. If so, you will be able to keep your old monitor settings instead of relyipage to the four mode buttons by right-clicking on them. When panning and zooming, you can use the Quick Access "follow display" feature whereby the panel always remains visible. To enable or disable this, click on the Quick Access system menu box in the upper left corner of the toolbar and select Follow Display (you can also press Alt+Space, then F to toggle this setting). You may want to put the Quick Access program in your Startup folder. To do so, right-click on the Windows 95 Taskbar and follow the on-screen instructions. The Quick Access program is located in the \Matrox\MGA\Qa directory. MGA Monitor Program The MGA Monitor Program is part of the MGA PowerDesk folder, which is accessible from the Programs fly-out on the Start menu. If you ever wish to find this program using the Browse button, it is located in the \Matrox\MGA\Mon directory. This program is for advanced users. Under normal conditions, you could rely on Windows 95 to provide acceptable monitor setup, based on the monitor you select during setup or on the Settings sheet on the Windows 95 Display Properties dialog box. The MGA Monitor program can be used in place of the Windows 95 mechanism under the following conditions: Your monitor is not found in the extensive list of monitors provided in the Windows 95 setup. You are upgrading from a previous MGA installation, and you wish to retain any customized monitor settings. You have a requirement to perform fine tuning of a highly technical nature on your display. Another advantage of the MGA Monitor Program is that you can test every Display area (resolution) and Color Palette (pixel depth) setting for your monitor selection before confirming your choice, thereby avoiding surprises when rebooting. For more details, read the on-line Help, which is accessible from the program. Warning: The MGA Monitor Program overwrites the Windows 95 monitor selection. If you change your monitor later on, remember to also change the monitor choice from within the MGA Monitor Program (otherwise, your display may not be correct when you reboot). The MGA PowerDesk Control Center will likely warn you about this, but as it cannot handle all cases, you may not be warned. For more details, read the on-line Help, which is accessible from the MGA Settings sheet in the Display Properties dialog box. Q & A (typical problems solved) Here are some common questions presented with some possible solutions. Q: Are the PowerDesk for Windows 3.1 features compatible with Windows 95? A: Absolutely not. After upgrading from Windows 3.1 to Windows 95, you must stop using the programs in the Windows 3.1 PowerDesk group. If you install Windows 95 on top of Windows without first uninstalling the old MGA software, you should delete the PowerDesk group folder and all its icons, then install the Windows 95 version of the MGA software. Q: I start Windows 95 and my monitor does not sync properly. What can I do? A: This probably happens because the MGA driver is trying to boot in a resolution that your monitor does not support. This could occur if you had never selected a monitor, or if you physically changed your monitor without informing Windows 95 (or the MGA Monitor Program). To recover from this problem, reboot your system (by pressing Ctrl-Alt-Del twice). When the screen displays "Starting Windows 95", press F5 to enter Windows 95 in "safe mode". In this mode, Windows 95 will boot in VGA at 640 x 480, and you will then be able to lower the resolution in the Display Properties dialog box. Pull it down to 640 x 480 and reboot again to get a display of 640 x 480 in MGA mode. Then take the appropriate actions to check and correct your monitor type. Q: I have a problem with an application that I suspect is caused by the display driver. What should I do? A: You can try using the application with the standard VGA driver, or alternately, try using the MGA driver, but with hardware accelerations disabled (see below). To restart in VGA mode, simply open the Display Properties dialog box (right-click on the desktop background), and change the Display Type to VGA. You will have to reboot. To restart using the MGA driver with hardware accelerations off, click on the System application in the Windows 95 Control Panel, then go to the Performance page. Select Graphics, then move the Hardware Acceleration bar to None. You will have to reboot as well, but you will still have the same Display area and Color Palette. This is often better than using standard VGA, as some applications exhibit problems, specifically in High Color or True Color modes. Q: Windows 95 reports a display adapter hardware conflict upon booting. I thought Windows 95 was Plug and Play! What can I do? A: This does sometimes happen. If you have changed display adapters, especially non-PCI ones, you should let the Windows 95 hardware detection program take the appropriate steps as suggested; this might solve your problem. If you have not changed any adapter, running this program is of no use. Instead, run the System application in the Control Panel, then select Device Manager, then Display Adapters. If you can't solve the problem here (or if no problem is reported), try re-installing the MGA driver from the original diskette. To do this, open the Display Properties window, click on Change Display Type, then re-select the MGA. Q: Can I use the MGA Multimedia Superpack CD-ROM under Windows 95? A: No, some programs will either not work well or not install well. A new CD-ROM that is compatible with Windows 95 will be available shortly. Q: Can I uninstall the MGA PowerDesk for Windows 95 software? A: Yes, but not by using the standard Windows 95 Install/Remove Applications in Control Panel, since PowerDesk is so fully integrated with the display driver. Here is what you must do (this should only be attempted by advanced users): Make sure you are not using a Desktop area that is larger than the Display area (look on the MGA Settings sheet in the Display Properties dialog box). Run \Matrox\MGA\Paneloff.reg to remove the MGA Settings page. Edit \windows\win.ini to remove mgactrl.exe from the load= line. Remove the MGA PowerDesk folder from the Programs flyout of the Start menu, then delete the \Matrox directory structure. More Information For more information, see the readme file included on the diskette. This file is also copied to the installation target directory (for example: \Matrox\MGA), and accessible through the MGA PowerDesk folder. 123ЖОј    +,=>JK]^qrwxˆ‰Š‹“”•ШЩЪъыђљѓэыщчхтрнлйзеЯЩУРНКЗДБЎЋЈЅЂŸœ™–”’Š„~|zxvtqV]]]]]] U]b c$ U]b c$ U]b c$]]]U]U]U]U]U]U]U]U]U]U]U]U]U]U]U] U]bc U]b c$ U]b c$]]]]U]]U]]]]] U]b c$ U]b c$ U]b c$,ђѓ)*=>MN`a{|ŒЋЌ­БНЫн IJKMYЪЫећќ45AFQЏАЮнfghl§ћљієђ№эыщчфтролйзеваЭЫЩЧФТРОМЙЗЕВАЎЋЉЇЄЂŸ›™–”’ŽŒŠˆ]]]]]]]U]]]]U]]U]]]U]]]U]]]U]]]]]U]]]]U]]U]]]]V]]]]V]]]]V]]]]V]]]]5lop}   " 6 4 5 6 B C D u v w С Т љ њ ћ  Ž Ј Љ    P Q R Р С Т ./ЃЄЅаќњїѕѓёяьъштмжаЪФСОЛИЕЏ­ЋЉЇЅЃ—‘Ž‹ˆ…ƒ~{uo U]bc U]bc]b]b]]]b]b]b]b U]bc U]bc U]bc]]]]]] U]bc]b]b]b]b]b U]bc U]bc U]b c$ U]b c$ U]b c$ U]b c$]]U]]]]]U]]U])абв!"#$TiŠœЁЎКЛыјYZŠ‘УФ”Іщъ8JЋЗ    456s„‘œžŸ љіѓ№эчхтрнлижгбЯЬЪШЦУСПНКИЖДБЏЌЊЈІЄž˜’‹ˆ†„‚€~]]]]]U]]U]] U]bc U]bc U]bc]]]]U]]U]]]]U]]]]V]]]]V]]]V]]U]]U]]V]] U]bc]b]b]b]b U]bc/ БВГ-%1VbЊЋЌЉЏ>?@AMNOS_šЌј]^_‰•—ЄЊГЙХуя>JџmљѓэышцусомкижваЮЬЪФОИЖГБЎЌЉЇЅЃЁžœ™—”’Šˆ…ƒ€~{y]U]]U]]U]]U]]U]]U]]U]]U]]]]]U]]U]]U]] U]b c$ U]b c$ U]b c$]]]]UV]]]]]U]]U]]U]] U]b c$ U]b c$ U]b c$/mno/01789     ' ( ) “ ˜ !&!>!J!Q!R!S!Х!Ц!Я!о!ђ!ў!8"9"л"ч"+#9#x#y#Ў#Е#@$N$Y$Z$[$\$§ћљїѕящчхуспнзбЫЩЦФСПМКИЖДВА­ЋЈІЄЂŸš˜–”‘ŒŠˆ‚| U]b c$ U]b c$]]V]]U]]]]U]]U]]]]U]]U]]]]]]]U]]U]]U]] U]b c$ U]b c$ U]b c$]]]]]] U]bc U]bc]]]]]/\$o$p$q$œ$Ѕ$Ы$г$у$ш$%%%C%R%]%^%_%&&6&H&T&U&V&О&П&Р&''‰'Š'х'ц'ч'/(;(M(Z($)%)&).)/)0)Ђ*Ѓ*Є*ъ*і*љѓэышцусомйздваЮЬЩЧФТРОМКИЖДВАЎЌЊЈЅЃ žœš”Žˆ†„‚€}U]]]]] U]bc U]bc U]bc]]]U]]U]]]]]]]]]]]]]]]U]]U]]]]]V]]U]]U]]U]]U]] U]b c$ U]b c$ U]b c$0і*++#+$+%+&+'+I+J+K+‘+’+“+м+н+:-;-<-‡-ˆ-˜.™.š.Л/Э/y0z0{0ф0х0‡1ˆ1‰1Б1У122526272…2‹2Њ2З2Ш2г2с2щ2љ23§њјієђ№ъфомкиеваЮЬЩЦФТРОЛЙЗЕВЏ­ЋЉЇЄЂŸ›™—”’Šˆ…ƒ€U]]U]]U]]U]]U]]]]]U]]U]]]]]U]U]]]]U]]]]]U]U]]]]U]U]]]] U]b c$ U]b c$ U]b c$]]]]]U]]2333^3j3o3|3444‚4ƒ4b5c5d5Н5У5з5ф5ђ5666Џ6С6д6ч6777D7E7г7д7е788D8_8c8p8§8ў8џ89)9B9N9\9h9w9‰9§њјѕѓ№юьъчфтромйздвЯЭЪШХУРОМКЗДВАЎЋЈІЃЁžœš˜–“‘ŽŒ‰‡„U]]U]]U]]U]]]]]U]]U]]U]U]]]]U]U]]]]U]]U]]U]]U]]U]]U]]]]]U]U]]]]U]]U]]U]]3‰9–9—9›9Г9Т9Ю9д9е9к9ъ9і9: ::::&:/:@:H:W:\:s:z:::‘:’:“:Ѓ:Є:Ѕ:У:Я:5;@;a;b;s;t;§ћљієёяэышцусомкиегаЮЫЩЦФТРОМЖАЊЈЅЃ žœš˜]]]]V]]U]] U]b c$ U]b c$ U]b c$]]]]]V]]U]]U]]U]]]]V]]V]]V]]]]U]]V]]]](23   ,>K^rx‰Š‹їђэшуойдЯХЛБЇ“‰uk ќР!№ ќР!№ ќР!№ ќР!№ ќР!№ ќР!№ ќР!№ ќР!№ ќР!№ ќР!№№№№№№№№№„№‹”•ЩЪѓ*N|њѕ№ыФvO& 4hЗАh˜ў№& 4hЗАh˜ў№& 4hЗАh˜ў№& 4hЗАh˜ў№№№№№|Ќ­JKЫќ5АигЮЩФ |X4# 4hЗh˜ў№# 4hЗh˜ў№# 4hЗh˜ў№# 4hЗh˜ў№№№№№& 4hЗАh˜ў№ Аgh  5 6 C D v w Т њ лжаЪЅŸzupkfa\W№№№№№№№$ 4hЗhh˜ў№h№$ 4hЗhh˜ў№h№h№№# 4hЗh˜ў№њ ћ Ž Љ   Q R С Т /љеБ‡‚}xsO# 4hЗh˜ў№№№№№h№# 4hЗh˜ў№# 4hЗh˜ў№# 4hЗh˜ў№h№ /ЄЅбв"$ЛZФлеаЫЦСyU# 4hЗh˜ў№# 4hЗh˜ў№# 4hЗh˜ў№№№№№h№# 4hЗh˜ў№ Фъ   56žŸ ВГЋЌлЗВ­ЅŸ{vqlgb]X№№№№№№№# 4hЗh˜ў№h№h˜ў№№№# 4hЗh˜ў№# 4hЗh˜ў№Ќ?@ANO^_no0189    ( ) R!S!њѕ№ыцсмзвЭШУОЙДЏЊЅ ›–№№№№№№№№№№№№№№№№№№№№№S!Ц!9"y#Z$[$\$p$q$^%_%U&V&лЗ“oje`[VQLG№№№№№№№№# 4hЗh˜ў№# 4hЗh˜ў№# 4hЗh˜ў№# 4hЗh˜ў№ V&П&Р&'Š'ц'ч'%)&)/)0)Ѓ*Є*$+%+&+њѕб­‰„zupkfa\W№№№№№№№№№№# 4hЗh˜ў№# 4hЗh˜ў№# 4hЗh˜ў№№№&+'+J+K+’+“+н+;-<-ˆ-™.š.z0њѕ№ыцТž™uQLFh№№# 4hЗh˜ў№# 4hЗh˜ў№№# 4hЗh˜ў№# 4hЗh˜ў№№№№№№ z0{0х0ˆ1‰1627244ƒ4c5d5љеБЌІ š”pLG№# 4hЗh˜ў№# 4hЗh˜ў№h№h№h№h№№# 4hЗh˜ў№# 4hЗh˜ў№h№ d577E7д7е78ў8џ8—9љѓЯЋІ‚^Y5# 4hЗа˜ў№№# 4hЗh˜ў№# 4hЗh˜ў№№# 4hЗh˜ў№# 4hЗh˜ў№h№h№ —9е9::‘:’:“:Є:Ѕ:b;t;лЗ“Ž‰„zup№№№№№№№# 4hЗа˜ў№# 4hЗа˜ў№# 4hЗа˜ў№ t;t;(t8џџџџџџџџ(iK@ёџNormala "A@ђџЁ"Default Paragraph Fontаџ@џџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџўџ џџџџ РFMicrosoft Word 6.0 Document MSWordDocє9ВqаЯрЁБс>ўџ аЯрЁБс>ўџ ўџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџ
