Since I posted these questions 3 weeks ago, I have received only two replies, both on the STB card. If you have Diamond SpeedStar card and 386/20 (or 25), I would be very interested in seeing its VIDSPEED benchmark. Thanks. ------------------------- 1. STB supports VESA through BIOS. How about Diamond, BIOS or driver? No response. ------------------------- 2. One person reported that 0 (zero) is not slashed on a STB clone. Is that true for the real STB one? From: jones@eng.buffalo.edu (terry a jones) > No. That is not true on the STB Ergo board. The zero's shape is different >than upper/lowercase 'O' and is slashed, or more correctly, has a dot in the >center. From: gerardka@ism.isc.com (Gerard Kam) > The zero is different for different size fonts. > The full size VGA zero has a veritical dash within the zero. > The compressed 53 line zero has the regular slash. ------------------------- 3. Refresh rates for individual resolutions can be set up at once on the Diamond board (for example 72@640, 60@800, 44@1024), so switching video mode automatically changes refresh rate. Does STB have the same feature? For STB, a jumper sets one of two refresh modes: 60 and 72. From what I understan, 640 and 800 resolutions must have the same refresh rate, and a setup program can choose the mode for 1024 resolution. Therefore, Diamond is more flexible in this respect. ------------------------- 4. Diamond already has Edsun and HiColor upgrades available. How about STB? No one has heard about it. ------------------------- 5. Diamond seems to be a much smaller company (22 people from what I read) and has fewer dealers. I sent letters to both STB and Diamond on 5/11/91 asking some technical questions. STB replied promptly, but I have not heard from Diamond yet. However, Diamond offers 5-year warranty versus STB's 2-year. Has anyone dealt with Diamond tech support? No response. ------------------------- 6. InfoWorld (4/15/91) reported that STB was faster than Diamond overall, but Diamond was (dramatically) faster on a couple of AutoCAD tests. If you have either of these cards and VIDSPEED 2.0 (available on Simtel20), I would appreciate it if you could run the test and send me the results (VIDSPEED * + > filename). Also, the PCMag video benchmark on the STB card with shadow BIOS *OFF* would be helpful. Please let me know the processor and clock rate used for the test, and the bus speed if known.
