Installation of the drivers a) Start the "Windows NT setup"-program of the group "main" and wait a moment. b) Open the menu "options" und select "Change System Settings". c) Open the option box for "Displays" of the new window "Change System Settings". d) In here scroll until the end and select "Others (Requires a disk from a hardware manufacturer)". e) A new window "Insert Disk" appears and you are requested to insert the installation disk "A:\". If necessary, the default selection can be overwritten. f) The window "Select OEM Option" appears and you get a list of the supported miro boards with their resolutions and frequencies. Select an appropriate resolution according to your board and monitor and wait a moment. g) The window "Change System Settings" appears again, indicating the selected driver at "Displays". Confirm by using the "Close" button. h) If you already installed the drivers in former times you are asked whether you want to install the former or the new drivers. Confirm the new installation by using the button "New". i) A new window "Windows NT Setup" appears and you are requested to insert the installation disk. Confirm by using the "Continue" button. j) Now you see the introduction menu of the setup-program. Leave the program now, e.g. by selecting the menu "Options" and "Exit". k) Windows NT gives you the information that the new driver will only be effected after a system reboot. In case of a board with two drivers available (e.g. 256 and 16.7 million colours) the procedure b) to i) has to be repeated for the second driver. If problems of the display driver occur when rebooting the system, you have the possibility to reselect the former configuration by using the option "last known good menu". If this doesn`t solve the problem you have to repair your system by using the Windows-NT-setup- disk/-CD and the "Emergency Repair Disk". The "Emergency Repair Disk" should include a configuration with a VGA-driver "640x480, 16 colors" and your system has to run properly with this driver under all circum- stances. So you can start trouble-shooting now. In order to repair your system only select the options "Inspect configuration registry" and "SYSTEM (System Configuration)". If you change the graphics board don`t forget to reconfigure your system on the VGA-driver before. So you get a properly running system after changing the board and you will be able to install the drivers for the new board. The S3-drivers on the Windows NT-Setup-CD don't run together with miroCRYSTAL 20SD (twin), miroCRYSTAL 20SV (ergo/twin), miroCRYSTAL 40SV (ergo/twin) and miroMAGIC 20SV/40SV ergo/twin. 4.) Change of resolutions and colour modes a) Start the "Windows NT setup"-program of the group "main" and wait a moment. b) Open the menu "options" und select "Change System Settings". c) Open the option box for "Displays" of the new window "Change System Settings". d) Select the desired resolution from the list of the drivers installed for your board and your monitor. Miro now inserts the version number into the description string. Select the desired resolution for your board and monitor with the highest version number to avoid the installation of an old old driver or the use of an old installation script. e) If the driver is not installed yet a new window "Windows NT Setup" appears and you will be requested to insert the installation disk. Confirm by using the "Continue"-button. f) If the driver has already been installed you will be asked whether you want to install the current or a new driver. Confirm the use of the pre-installed driver by using the "Current"-button. g) Now you see the introduction menu of the setup-program again. Leave the program now ( e.g. by using the menu "Options" and "Exit"). h) Windows NT gives you the information that the new driver will only be effected after a system reboot. 5.) Special hints concerning the truecolor driver The truecolor-driver is created as an accelerated framebufferdriver in the flatmodel. As a basic address of the framebuffer the driver presets the following 32-bit addresses: - board for VL-bus : FE80.0000 (hex) - board for PCI-bus : FE80.0000 (hex) If the boards don't run with these addresses (e.g. as a result of an incomplete address decoding of your motherboard) the addresses can be overwritten by an entry into the registry. Repair your system by applicating the measurements described at 3) together with the VGA- driver. Start the registry-editor REGEDT32.EXE of the \WINNT\SYSTEM32 directory. Use its help-function for operating. Look for the key HKEY_LOCAL_MACHINE on Local Machine \SYSTEM \CurrentControlSet \Services \miroFlatModel \Device0 Select EDIT and AddValue with your mouse. Insert the ValueName "FrameBufferBaseAddress" and the DataType "REG_DWORD". In the following menu-box insert a new address that will shurely work on your computer. After the confirmaton you will find the new inserted address beside data e.g. concerning resolution and colour-mode in the right window. You can delete this value by indicating with the mouse and pressing the DEL-Key. Take care not to change or delete any other value - your system would not be able to run after a system-reboot! One of the following versions of the installation disk will include a DOS-test-program that enables you to check a miro-board concerning available addresses. 6.) Association of the drivers with the various boards - CRYSTAL.SYS and CRYSTAL.DLL : 256 colours driver for - miroCRYSTAL 20SD (twin) - miroCRYSTAL 20SV (ergo/twin) - miroCRYSTAL 40SV (ergo/twin) - miroMAGIC 20SV/40SV ergo/twin - FCRYSTAL.SYS and FCRYSTAL.DLL : Highcolor- and Truecolor-driver for - miroCRYSTAL 20SD (twin) - miroCRYSTAL 20SV (ergo/twin) - miroCRYSTAL 40SV (ergo/twin) - miroMAGIC 20SV/40SV ergo/twin - S3.SYS and S3.DLL : 256 colours driver for - miroCRYSTAL 10SD 7.) Delete drivers Drivers that will no longer be used or that are out of date can be removed by reconfiguring with the Windows NT setup-program a different driver (e.g.: VGA Standard 640x480, 16 colors), rebooting the system and then deleting with the help of the file-manager at \WINNT\SYSTEM32 the display-driver (extension: .DLL) and at \WINNT\SYSTEM32\DRIVERS the miniport-driver (extension: .SYS). From now on miro adds the file-time to the version number. After the installation of drivers with the option "Other..." there will exist several files OEMVIOx.INF (x=0,1,...) in the directory \WINNT\SYSTEM32. These are the renamed installation scripts of the current and the former installation disks. You should delete all of them except the file with the highest 'x' (the current installation). If you don't do so, drivers will be listed several times and by different installation disks and versions. Moreover the refering key should be deleted in the registry with the help of the registry-editor REGEDT32 (look at 4.) ). Look for the key HKEY_LOCAL_MACHINE on Local Machine \SYSTEM \CurrentControlSet \Services \miro8BPP for the 256 colours driver \miroFlatModel for the highcolor- / truecolor-driver \s3 for the driver for 10SD Select the key in the left window with your mouse and delete it with the DEL-key. Take care not to change or delete any other key - your system would not be able to run after a system-reboot! 8.) Supported resolutions and frequencies of the various boards With this disk-release miro changes the original timings of these drivers to timings that are approximated to the VESA-standards. Horizontal and vertical refresh rates are approximated data and may change according to the technical and market development. The timings for resolutions of 1408x1024 pixels are not part of the VESA-standards but are adapted to them by miro. - miroCRYSTAL 40SV (ergo/twin), miroMAGIC 40SV ergo/twin 640 x 480: 31,5kHz/60Hz 37,5kHz/75Hz (256, 65k, 16,7M colours) 800 x 600: 38kHz/60Hz 47kHz/75Hz (256, 65k, 16,7M colours) 1024 x 768: 48,5kHz/60Hz 60kHz/75Hz (256, 65k, 16,7M colours) 1280 x 1024: 64kHz/60Hz 80kHz/75Hz (256, 65k colours) 1408 x 1024: 66kHz/60Hz 74kHz/70Hz (256, 65k colours) - miroCRYSTAL 20SV (ergo/twin), miroMAGIC 20SV ergo/twin 640 x 480: 31,5kHz/60Hz 37,5kHz/75Hz (256, 65k, 16,7M colours) 800 x 600: 38kHz/60Hz 47kHz/75Hz (256, 65k, 16,7M colours) 1024 x 768: 48,5kHz/60Hz 60kHz/75Hz (256, 65k colours) 1280 x 1024: 64kHz/60Hz 80kHz/75Hz (256 colours) 1408 x 1024: 66kHz/60Hz 74kHz/70Hz (256 colours) - miroCRYSTAL 20SD (twin) 640 x 480: 31,5kHz/60Hz 37,5kHz/75Hz (256, 65k, 16,7M colours) 800 x 600: 38kHz/60Hz 47kHz/75Hz (256, 65k, 16,7M colours) 1024 x 768: 48,5kHz/60Hz 60kHz/75Hz (256, 65k colours) 1280 x 1024: 64kHz/60Hz 80kHz/75Hz (256 colours) - miroCRYSTAL 10SD 640 x 480: 31,5kHz/60Hz 38kHz/72Hz (256 colours) 800 x 600: 38kHz/60Hz 48kHz/72Hz (256 colours) 1024 x 768: 48kHz/60Hz 56kHz/70Hz 60kHz/75Hz (256 colours) 1280 x 1024: 64kHz/60Hz 78kHz/72Hz 48kHz/87Hz-interlaced (256 colours) 1280x1024 with 256 colours with a miroCRYSTAL 10SD can only be effected with a RAM upgrade to 2MB 9.) Special hints for miroCRYSTAL/miroMAGIC 20SV/40SV twin/ergo and miroCRYSTAL 20SD twin If you want to install/configure the graphics board "miroCRYSTAL 40SV ergo/twin" resp. "miroMAGIC 40SV ergo/twin" please select "miroCRYSTAL 40SV" in the setup-program. If you want to install/configure the graphics board "miroCRYSTAL 20SV ergo/twin" resp. "miroMAGIC 20SV ergo/twin" please select "miroCRYSTAL 20SV" in the setup-program. If you want to install/configure the graphics board "miroCRYSTAL 20SD twin" please select "miroCRYSTAL 20SD" in the setup-program. This version of drivers do not support the "TWINFACE" mode of the miroCRYSTAL 20SV/40SV twin. However, the output is switched to the second HiRes board and -monitor. Despite the VGA DOS box is displayed in full screen mode on the first monitor. 10.) If problems occur... In case of problems with the VGA-DOS-box in fullscreen-mode you should ask your dealer or miro for an update of the BIOS-ROM. A unsyncroniced image may be caught by switching between the windowed- and the fullscreen-mode of the VGA-DOS-box. The VGA-DOS-box as a part of the operating system only supports the resolutions available for a 'standard VGA', e.g. display modes up to 320x200 pixels with 256 colors or 640x480 pixels with 16 colors. If a DOS application tries to use a higher resolution, the VGA-DOS-box, or, in the worst case, the hole system might crash.
