I just bought a Tricom Mega/1024 VGA board that I want to use with my Hyundai HCM-421E monitor for running X386. They had two different types of these VGA boards at the store (same price). The 'old' style board had 3 or 4 different crystals on it, and I believe the highest one was around 60MHz. The 'new' style board only had one 36MHz crystal on it. I bought the 'new' one because it had higher rev EPROMS on it. When I ran Thomas Roell's clock.exe program it detected clocks at 25.2, 28.3, 32.5 and 36.0. Would I be better off with the 'old' or 'new' style VGA board? I am using the monitor in 8514 emulation mode. -- Steve Kotsopoulos mail: steve@ecf.utoronto.ca Systems Analyst bitnet: steve@ecf.UTORONTO.BITNET Engineering Computing Facility uucp: uunet!utai!ecf!steve University of Toronto phone: (416) 978-5898

I looked at the manual since I cannot do turbo pascal. In the back it said I had, 25 28 36 40 45 65 (rounded of course). That seemed to keep everyone happy. > >Would I be better off with the 'old' or 'new' style VGA board? >I am using the monitor in 8514 emulation mode. Do not know. I've had not problems except one: 1024x768 in non-interlace mode. Details, under windows 3.0 1024x768 always came up in interlaced mode UNLESS I ran some silly utility from the disc that came with the board that said to do 1024x768 specific in non-interlaced mode, called mode 38 or something. This program apparantly talked to the VGA BIOS and told it next time, do it in non-interlace mode. If I tell Roell's wonderfull X386 to run in 1024x768 non-interlace, the screen simply goes blank. Works fine in interlace-mode though. I suppose I will have to get around to finding out what this silly utility did and emulate it in UNIX. Any ideas anyone? Hope this helps in some unseen way ... -- *********************************************************************** | Karl Nicholas | A million monkeys in a million years | | karln!karln@uunet.uu.net | did write Shakespear, we evolved ... | ***********************************************************************
