Hence, the odd oscillator assortment. The ProDesigner II adapters are able to generate timings from the single clock. U1 Outline for 28MHz osc U9 Outline for 40 MHz osc system clock U19 Outline for 65MHz osc Pixel clock, graphics mode U22 45.0000 MHz osc U23 Outline for 36 MHz osc U30 Outline for 25 MHz osc Y1 Glare MHz osc Why no Translation ROM? The ProDesigner II / MC supports VGA and better. It does NOT support Hercules, CGA and EGA. The Translation ROM has no purpose in this case. Memory Supported The ET4000 supports 16Kx4 and 256Kx4 DRAM, plus it supports 256Kx4 VRAM. There are 8x 256Kx4 installed for a total of 1,024Kx8, akin to the XGA and XGA2. Don't be confused if you see a reference to "1M" chips, they are 1Mbit chips, so you need 8 to get a full 1MByte... ADF Sections for @0086h "Orchid Pro II/MC v2.0/HiColor" NumBytes 3 FixedResources pos[0]=XXXX11XXb pos[2]=X01XXXXXb ; place VCO in known state Adapter ROM BIOS Address Select 'Address C000 x 24K' for the standard DAC, 'Address C000 x 32K + HC' if the Sierra SC11482CV/SC11483CV HICOLOR DAC is installed. The SC1148x RAMDACs support 15bpp modes.With Sierra HICOLOR DAC support enabled, the ROM size increases from 24,576 bytes (24Kb) to 32,768 bytes (32Kb). If another adapter's resource setting is in conflict then the other adapter's resource setting must be changed to resolve the conflict. <Address C000 x 24K [C000- C5FF]>, C000 x 32K + HC [C000-C7FF], ROM Disabled Monitor Type Select type of monitor connected to the ProDesigner II/MC. <Color>, Monochrome (gray scale) Vertical scan frequency @ 640x480 The ProDesigner II/MC can work with monitors that can operate at very high vertical scan rates. These higher rates can reduce video image flicker. If you are unsure if the monitor attached can operate at the higher rates at this resolution, do not change this setting. Instead, leave this setting at the default, '60Hz', then reboot the machine into DOS. Run MCSCREEN on the ProDesigner II/MC Option and Utility disk. This program allows you to dynamically change the resolutions and vertical scan rates generated by the ProDesigner II/MC. Use it to determine if the monitor can operate at the higher rates - making a note of the what resolutions, and rates, that worked with the monitor. Then re-run 'setup' on the reference disk and change this setting. <60Hz>, 72Hz Vertical scan frequency @ 800x600 The ProDesigner II/MC can work with monitors that can operate at very high vertical scan rates. These higher rates can reduce video image flicker. If you are unsure if the monitor attached can operate at the higher rates at this resolution, do not change this setting. Instead, leave this setting at the default, '56Hz', then reboot the machine into DOS. Run MCSCREEN on the ProDesigner II/MC Option and Utility disk. This program allows you to dynamically change the resolutions and vertical scan rates generated by the ProDesigner II/MC. Use it to determine if the monitor can operate at the higher rates - making a note of the what resolutions, and rates, that worked with the monitor. Then re-run 'setup' on the reference disk and change this setting <56Hz>, 60Hz, 72Hz Vertical scan frequency @ 1024x768 The ProDesigner II/MC can work with monitors that can operate at very high vertical scan rates. These higher rates can reduce video image flicker. If you are unsure if the monitor attached can operate at the higher rates at this resolution, do not change this setting. Instead, leave this setting at the default, '45Hz', then reboot the machine into DOS. Run MCSCREEN on the ProDesigner II/MC Option and Utility disk. This program allows you to dynamically change the resolutions and vertical scan rates generated by the ProDesigner II/MC. Use it to determine if the monitor can operate at the higher rates - making a note of the what resolutions, and rates, that worked with the monitor. Then re-run 'setup' on the reference disk and change this setting <45Hz - Interlaced>, 60Hz - Non-Interlaced, 70Hz - Non-Interlaced Video I/O Cycle Select This should not be changed. It is for use by Orchid's manufacturing division. <Default >, Extended |
