Supported boards and colour modes - miroRAINBOW Win : 8 bit (256 colours) - miroMAGIC S4 : 8 bit (256 colours) - miroCRYSTAL 32S : 8 bit (256 colours) - miroCRYSTAL 24S : 8 bit (256 colours) - miroCRYSTAL 16S : 8 bit (256 colours) - miroMAGIC plus : 8 bit (256 colours) - miroRAINBOW Win : 32 bit (16.7 million colours) (only with EISA-, VL- und PCI-bus) - miroMAGIC S4 : 32 bit (16.7 million colours) (only with EISA-, VL- und PCI-bus) - miroCRYSTAL 32S : 32 bit (16.7 million colours) (only with EISA-, VL- und PCI-bus) 3.) Installation of the drivers a) Start the "Windows NT setup"-program of the group "main". b) Wait a moment. c) Open the menu "options" und select "Change System Settings". d) Open the option box for "Displays" of the new window "Change System Settings". e) In here scroll until the end and select "Others (Requires a disk from a hardware manufacturer)". f) A new window "Insert Disk" appears and you are requested to insert the installation disk "A:\". If necessary, the default selection can be overwritten. g) 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. h) Wait a moment. i) The window "Change System Settings" appears again, indicating the selected driver at "Displays". Confirm by using the "Close" button. j) 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". k) A new window "Windows NT Setup" appears and you are requested to insert the installation disk. Confirm by using the "Continue" button. l) Now you see the introduction menu of the setup-program. Leave the program now, e.g. by selecting the menu "Options" and "Exit". m) 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 c) to k) 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 NT-Setup-CD don't run together with miroRAINBOW Win, miroMAGIC S4, miroCRYSTAL 32S, miroCRYSTAL 24S and miroCRYSTAL 16S. 4.) Change of resolutions and colour modes a) Start the "Windows NT setup"-program of the group "main". b) Wait a moment. c) Open the menu "options" und select "Change System Settings". d) Open the option box for "Displays" of the new window "Change System Settings". e) 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. f) 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. g) 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. h) Now you see the introduction menu of the setup-program again. Leave the program now ( e.g. by using the menu "Options" and "Exit"). i) 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. At the moment, it only supports miro-boards that are equipped with 4 MB. As this memory is completely located into the address range of the PC this driver doesn't run together with ISA- boards because the ISA-bus system includes a addressing restriction of 16MB an nomally these addresses are already reserved for the main memory in case of NT-computers. As a basic address of the framebuffer the driver presets the following 32-bit addresses: - board for EISA-bus : 07C0.0000 (hex) - board for VL-bus : FEC0.0000 (hex) - board for PCI-bus : FEC0.0000 (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 - RAINBOW.SYS and RAINBOW.DLL : for miro-Boards with 4 MB memory - miroRAINBOW Win - miroMAGIC S3 - miroCRYSTAL 32S - CRYSTAL.SYS and CRYSTAL.DLL : for miro-Boards with 3 MB and 2 MB memory - miroCRYSTAL 24S - miroCRYSTAL 16S - MAGIC.SYS and MAGIC.DLL : for miroMAGIC plus - FCRYSTAL.SYS and FCRYSTAL.DLL : Truecolor-driver for miro-Boards with 4 MB memory (only with EISA-, VL- and PCI-bus) - miroRAINBOW Win - miroMAGIC S3 - miroCRYSTAL 32S 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 \MiroRainbow for the driver for 4 MB boards \MiroCrystal for the driver for 3 MB and 2 MB boards \miroFlatModel for the Truecolor-driver \MiroMagic for the miroMAGIC plus driver \MiroCrystal16s out of date (diskversion 1.01) \MiroCrystal24s out of date (diskversion 1.01) \MiroCrystal32s out of date (diskversion 1.01) 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 (horizontal and vertical scan frequencies are approximate values and depend on technical and marketoriented development): - miroRAINBOW Win, miroMAGIC S4, miroCRYSTAL 32S 640 x 480, 16.7M colours, 31 kHz/60 Hz 38 kHz/72 Hz 800 x 600, 16.7M colours, 38 kHz/60 Hz 46 kHz/72 Hz 1024 x 768, 16.7M colours, 48 kHz/60 Hz 58 kHz/72 Hz "64 kHz" "71 kHz" "85 kHz" 640 x 480, 256 colours, 54 kHz/107 Hz 61 kHz/120 Hz 800 x 600, 256 colours, 60 kHz/94 Hz 66 kHz/103 Hz 1024 x 768, 256 colours, 51 kHz/62 Hz 63 kHz/77 Hz 67 kHz/82 Hz 1152 x 864, 256 colours, 57 kHz/62 Hz 61 kHz/68 Hz 69 kHz/76 Hz 1280 x 1024, 256 colours, 57 kHz/52 Hz 62 kHz/58 Hz 77 kHz/72 Hz 1408 x 1024, 256 colours, 64 kHz/59 Hz 71 kHz/67 Hz 71 kHz/67 Hz - miroCRYSTAL 24S, miroCRYSTAL 16S "48 kHz" "58 kHz" "64 kHz" 640 x 480, 256 colours, 48 kHz/95 Hz 48 kHz/95 Hz 36 kHz/70 Hz 768 x 576, 256 colours, 48 kHz/78 Hz 48 kHz/79 Hz 51 kHz/82 Hz 800 x 600, 256 colours, 48 kHz/75 Hz 48 kHz/75 Hz 50 kHz/77 Hz 1024 x 768, 256 colours, 50 kHz/61 Hz 61 kHz/75 Hz 64 kHz/79 Hz 9.) Hints concerning miroCRYSTAL 8S and miroCRYSTAL 16Si The graphics boards miroCRYSTAL 8S and miroCRYSTAL 16Si are supported by the Windows NT-included drivers for S3-boards. Therefor select the driver "S3 60Hz" respectively "S3 70Hz"in the SETUP-program. The following resolutions will be effected: 640 x 480, 256 colours, 31 kHz/60 Hz 38 kHz/72 Hz 800 x 600, 256 colours, 38 kHz/60 Hz 48 kHz/72 Hz 1024 x 768, 256 colours, 48 kHz/60 Hz 56 kHz/72 Hz If the driver "S3 Default Refresh" will be selected, it configures according to the DIP-Switches settings. Please refer to the manual belonging to the board. The resolution 1280 x 1024 with 256 colours is not available with the miroCRYSTAL 8S, miroCRYSTAL 8S/2MB and miroCRYSTAL 16Si. 10.) If problems occur... The miro Power Pack (miroMAGIC S4 and miroCRYSTAL 8S) and miroTWINFACE are not supported by the NT-drivers. You just can install drivers for the first board ("DOS-text/graphics") or you must remove the first board from your system and set the jumpers of the second board ("only HIRES-graphics") to declare it as the first board. Refer to the manual. 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.
