In case both options will be displayed, please select the model which is corresponding to your miro graphics adapter and click "apply". The computer is restarted. After the restart the new resolutions are available. Important hints for the installation: ===================================== 1.) Don't try to use former miro Windows 3.xx drivers for Windows 95. In case you tried to use these drivers make sure that all former miro Windows 3.xx drivers and entries in your SYSTEM.INI file are removed. In the SYSTEM.INI you have to remove the complete entries in the section [928.drv], [Twin.right] and [Twin.left]. Delete in your Win95 the follo- wing files if available: Del \\OEMMAGS4.* Del \\OEMRAIN.* Del \\OEMCR32S.* Del \\OEMCR24S.* Del \\OEMCR16S.* Del \\OEMC16SI.* Del \\OEMCR8S.* Del \\OEMC10SD.* Del \\OEMC20SD.* Del \\OEMC20SV.* Del \\OEMC40SV.* Del \\OEMMAG40.* Del \\OEMMAG20.* Del \\OEMC20TW.* Del \\OEMBIBO*.* Del \\MAGS4*.DRV Del \\RAIN*.DRV Del \\CR32S*.DRV Del \\CR24S*.DRV Del \\CR16S*.DRV Del \\C16SI*.DRV Del \\C8S*.DRV Del \\1SD*.DRV Del \\C20SD*.DRV Del \\C20SV*.DRV Del \\C40SV*.DRV Del \\M20*.DRV Del \\M40*.DRV Del \\TW10*.DRV Del \\TW20*.DRV Del \\TWIN.DRV Del \\OCTO.MON Del \\OCTOVGA.* Del \\MAGIC_S4.BMP Del \\RAIN_WIN.BMP Del \\MINFO.TXT Del \\MWINTOOL.INI Del \\MSUP*.* Del \\MONSEL.* Del \\VIRTDLL.DLL Del \\MFONTCOM.EXE Del \\MIROSCOP.EXE Del \\MIROHOOK.DLL Del \\MSCOPE*.HLP Del \\MPWRSAVE.SCR Del \\TWIN*.* Del \\MTINT*.* Del \\MSIZE*.* Del \\WSIZER.* Del \\WADJUST.* Del \\MIROLOGO.RLE Delete the miroWINTOOL group and the includes icons on your Windows95 desktop too !!! 2.) In case you are using a miro monitor or a common model please install a new monitor file. This monitor.inf file is on this installation disk. Make sure that there is no older OEM*.INF monitor file in your Win95\INF subdirectory. This subdirectory is hidden, but you can make it visible by entering the DIR /a command. All INF files are ASCII files and you can read these files with every editor, so please make sure that you don't delete needed INF files. Look into the file before you delete it !!! If you are using the miro monitor files of the original Windows 95 CD, please use the miro monitor file of this disk. 3.) Everytime you install new display drivers in Windows 95 a new OEM*.INF file will be copied into your WIN95\INF subdirectory. Windows 95 doesn't remove the old *.inf files. Make sure that only the specified OEM*.INF file is available. This could prevent many problems! 4.) Remember that all miroVIDEO graphics boards (VIDEO 20SD, VIDEO 20SV, VIDEO 40SV ergo) need an IRQ 5.) In case Windows 95 doesn't start VLB computers, you can change the base- address for the linear memory adressing: System.ini: [Display] LinBase= i.e. 40320, 60000, or 104858 6.) For miroVIDEO graphics boards (VIDEO 20SD, VIDEO 20SV, VIDEO 40SV ergo) you can switch the hardware scaler off or improved. The entry are as follows: System.ini [Display] VideoStretch= Standardvalues: greatest security : 257 best video + security : 259 best optic + security : 771 greatest performance : 261 best optic + performance : 775 The Value can be calculated as follows: [0 / 1] for DIB scaling by hardware [off / on] + [0 / 2] for DIB interpolation by hardware [off / on] + [0 / 4] for DIB scaling parameteradaption [off / on] + [0 / 256] for DDB scaling by hardware [off / on] + [0 / 512] for DDB interpolation by hardware [off / on] 7.) A DIB-engine driver is not usable for Video for Windows, but the optimized drivers can be fully used, if the Pinboard will set the entries depending on the selected display mode in the Win.ini file. ->If possible start the Pinboard always starting Windows 95. The Pinboard will correct the entries of Video for Windows automaticly. 8.) Using the miro Pinboard it could happen that, the switching from the virtual modes into the real modes doesn't work at once. In this case we recommend to switch first into the real mode resolution (640 x 480) and after this into a higher resolution. 9.) For the miroCRYSTAL 20SV the highest resolution of 1408 x 1024 in 8 bit is in Windows 95 at this time not available. This resolution will be available with the next driver update. t couls happen that a resolution will be offered in the Controlpanel, but you can't switch to this reso- lution. This means Windows 95 will fall back to the earlier resolution. 10.) During the installation of a miroVIDEO 20SD in Windows 95 it could happen that both busadapter versions will be displayed. Make sure that you select the right businterface, that means either PCI, or VLB, depending of the businterface of your miro graphics board. Otherwise the miro graphics board can't be installed for Windows 95 and the drivers doen't work.
