I am trying to get a standard 8-bit vga card to work in my 286 vlsi machine. The card does work (or let's assume this for now). I can get it to work but no software will put an image on the monochrome vga screen in vga mode! I did use the setup program for the computer and the vgaplus.exe program to switch modes etc. No dipswitch on the 286 board, just a jumper to select mono or color; I have the jumper set to color ...should I try mono??? I can use the vgaplus.exe program to switch to other modes, and software all works fine in cga mode, but I want to use the vga resolution. YES, the software I'm trying to use does support vga resolution. Can anybody please steer me in the right direction anyway??? Drowning in vga hell here...

Um, it's a wild guess, but I'd say that if you're using a monochrome monitor, you should probably have the system set to mono. Also, note that you probably won't be able to use the color VGA modes with your mono monitor. -- Marc Unangst | mju@mudos.ann-arbor.mi.us | "Bus error: passengers dumped" ...!umich!leebai!mudos!mju |

I am running a VGA-16 card on my 286-12, and I have the switch set to color. I run CGA, EGA and VGA color modes on my Mono VGA monitor without any trouble. If your monitor is TTL, however, then you cannot [correct me if I'm wrong, no flames please :-) ] run at VGA resolutions. My monitor has 64 shades of grey, and I find that it has a sharper picture than most Color VGA monitors (variable frequency excepted...). -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ HCPIV (2b||!2b) ~ Harry Pulley ~ harry@aeshq.UUCP ~ ~ Computo, ergo sum ~ Environment Canada ~ TOR, ON, CA ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A mono VGA system is no different from a color VGA system except that all you can get is grayscale. That is, colors are displayed in different intensities of gray. You should be able to set it up as a VGA system and have it work. That means selecting the color dipswitch setting. Of course, perhaps your system doesn't support VGA?

Yes, you get gray- scales, but only sixteen, not 256 because the monitor works only on the green line. My Paradise card auto-detects whether the monitor is color or mono, I believe by putting a signal out on each line, and checking to see if it gets a signal on the corresponding ground, and configures accordingly. Windows 3.0 has a special vga-mono driver, and none of Paradise's extended VGA Windows drivers work because they are all for color. My motherboard CMOS BIOS setup has a VGA setting which I use. Really old XTs had two dip switches, if I recall, with a setting for none, mono, and color; none being the appropriate setting for a VGA. -- Kaleb Keithley Jet Propulsion Labs kaleb@thyme.jpl.nasa.gov causing trouble again.

Randy Padawer > Internet: Justin_Randall_Padawer@cup.portal.com Whose standard 8-bit card? What's the clock speed of your motherboard? I ask because I have an ATI VGA VIP card that works well in a 10 mHz unit and chokes in a 12 mHz unit ... and I have to assume it just won't support the higher speed...
