A friend of mine wants to run EGA programs on his IBM-compatible. He has a Tandy RGB monitor connected. He finds that his EGA programs will not run. Are there any drivers, etc. that will allow him to do this? -- Eric Sheppard Georgia Institute of Technology, Atlanta Georgia, 30332 uucp: ...!{allegra,amd,hplabs,seismo,ut-ngp}!gatech!prism!ce1zzes ARPA: ce1zzes@prism.gatech.edu

Well, you left out alot of information, so I will have to guess what is
really in the system.
If it is what I think it is, the PC has a CGA display board and display.
It will NOT run EGA programs, period. You will have to replace the CGA
display board and monitor with an EGA display board and an EGA monitor.
There is nothing else that can be done.
Even if someone made a TSR that grabbed EGA calls and converted the calls
and data into CGA, the display will still look like CGA. It may actually
be worse, since CGA only handles something like 4 colors at a time, the
EGA pallette can't be efficently converted.
Time for new hardware.

A cheaper alternative is to just upgrade the graphics adapter to one that supports EGA on an RGB monitor. The ATI EGA Wonder will do that. The only drawback is that then EGA display is interlaced on an RGB monitor.

The 4 color limit is a function of the CGA adapter, not the monitor. The ATI card will allow the full range of 64 EGA colors on an RGB monitor (only 16 at a time of course). > >Time for new hardware. >-- > harvard\ att!nicmad\ >Vidiot ucbvax!uwvax..........!astroatc!brown > rutgers/ decvax!nicmad/ > ARPA/INTERNET: brown%astroatc.UUCP@spool.cs.wisc.edu Stephen Corbin {bu-cs,decvax,necntc,talcott}!encore!corbin corbin@encore.COM

Yes and no. Yes the 4 color limit is built in the CGA display description. No because the pallette for the CGA is only 16 colors, not the EGA 64. Why, because CGA RGB monitors are RGBI, while EGA monitors are RGBrgb. It will be virtually impossible to display the 64 color EGA pallette on a monitor that can physically only handle 16 colors. I still maintain to get FULL EGA functions will require an EGA card and an EGA monitor. Doing anything less and you will be cheating yourself. -- harvard\ att!nicmad\ Vidiot ucbvax!uwvax..........!astroatc!brown rutgers/ decvax!nicmad/ ARPA/INTERNET: brown%astroatc.UUCP@spool.cs.wisc.edu

I don't know the monitor, but you can't get 64 colors with only 4 digital pins.
If you can, you might as well rewrite the math books. Your monitor is EGA.
Your monitor has to be using 6 digital pins (RGBrgb). Get out the manual for
the monitor had check the wiring of the RGB connector.

I am experiencing a well-liked problem. :-) I am running various PD games and they seem to run TOO fast. I am using 8bit EGA card with EGA monitor. Also 80386 based at 20MHZ. I turned the TURBO switch off and games still fly-by!! Is there a key-combination which will slow the 386 down to about 8MHz or slower??!!! HELP!

I have Seagates 277R (65.5 MB hard drive), and recently used OnTracks's utility. The screen says :"It MAY be a good idea to back up the hard drive before using this program." I took "MAY" lightly. It should have said "IF you continue you will lose everything, including your appetite!!! Exit now or forever live in sin." Because the program did a low-level format before I could stop it!!! I lost everything. Personally I hate OnTrack's software, and my dog ate it for lunch. I called Seagate and they said "Did you have it backed up?" "No" "Nothing we can do for you." Heed this warning: Backup your hard drive before using any new File manipulation program or utility. Also backup weekly too. I also came across some utilities made for MS-DOS 3.3 which assumed you were using MS-DOS 3.3 (and never told you not to use it with 4.01! Since 4.01 came out after 3.3). These utilities screwed up the FAT on the disk terribly. Case-in-point: MS-DOS 3.3 can only "See" up to 32 MByte of storage at one time due to limitation on FAT. 4.01 can "see" very-very large MB. Which is why I chose MS-DOS 4.01 for 277R with 1 65.5 MB partician!!! Excellent! Then I just use subdirectories. I hope to but another HD for drive d....

I have a somewhat similar problem: Recently I bought a CGA card to accompany my Hercules. I had heard that some CGA cards had RGB outputs and my Amiga 1040 Monitor has RGB inputs as well as composite, so I figured what the heck... Well instead of going and spending another $10-15 on a RGB cable I tried hooking the card up through the composite port. To my dismay I found that that there was absolutely no horizontal or vertical sync, nor was there any color. Has anyone out there tried to do this before? I don't want to waste 10$ making an RGB cable and then find out that isn't going to work either. Any suggestions? (** I still don't have a real .sig... **)

Which is why >I chose MS-DOS 4.01 for 277R with 1 65.5 MB partician!!! DOS 4.xx also has a slightly different way that it sets up the parameter block in the boot sector of large partition hard disks. It uses a 32 bit format for some of the info instead of 16. A few of the DOS service routines will return 32 bit quantities instead of the 16 bit quantities in DOS 3.3. IF you are running DOS 4.xx, you need to carefully check out ANY and ALL software that may directly manipulate the disk or you're begging for trouble!! -- fredb.
