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 the following files in Win95 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 Also delete the miroWINTOOL program group and the icons on your Windows95 desktop!!! 2.) In case you are using a miro monitor or a common model please install a new monitor file. This installation disk contains this monitor.inf file. 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 required 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.) Every time 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 22SD, 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=
(MB) i.e. 64, 128, or 192 6.) For miroVIDEO graphics boards (VIDEO 20SD, VIDEO 20SV, VIDEO 22SD, VIDEO 40SV ergo) you can switch the hardware scaler off or improved. The entries are as follows: System.ini [Display] VideoStretch= Default values: greatest security : 257 best video + security : 259 best display quality + security : 771 greatest performance : 261 best display quality + 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 parameter adaption [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 miroPINBOARD will set the entries depending on the selected display mode in the Win.ini file. ->If possible, start the miroPINBOARD always starting Windows 95. The miroPINBOARD will correct the entries of Video for Windows automatically. 8.) Using the miroPINBOARD it may happen that switching from the virtual modes to the real modes doesn't work at once. In this case we recommend to switch into the real mode resolution (640 x 480) first and after this to a higher resolution. 9.) If it happens that both bus adapter versions will be displayed. Make sure that you select the right bus interface that means either PCI, or VLB, depending of the bus interface of your miro graphics board. Otherwise the miro graphics board can't be installed for Windows 95 and the drivers won't work. 10.)Combination of miroVIDEO DC20 and S3 based graphics boards in mainboards with AWARD BIOS: 868 and 968 S3 chips etc. need a linear adress area of 64MB under Windows 95. The current AWARD BIOS reserves an address area of 32MB for this graphics boards only. In case the memory area of the miroVIDEO DC20 is located directly after the memory area of the S3 based graphics board make sure that there is a memory area of 64MB between the graphics board and the miroVIDEO DC20 memory area. You can change the memory area in Windows 95 in your System Control Panel in the Device Manager in the Resources tab. 11.)During the installation of Lotus Smart Suite 4.0 under Windows 95 the background bitmap of Lotus won't be displayed properly, but there are no limitations using the functions of this software package. In the next driver release this bug will be fixed.
