I have a PC7300 with a DOS-73 card. I am running a program on DOS that looks for a Hercules graphics card which the PC7300 is supposed to emulate under DOS. However when the program attempts to use the graphics mode, the screen blanks, garbage appears on the screen, the screen blanks again and the Wide Font/Thin Font areas on the screen change to Graph Up/Graph Down. Any keystroke restores the screen to the normal text mode. How can I get the graphics to work under DOS? I have a 20MB disk (Miniscribe?) and I have just obtained a 80MB Seagate ST4096 that I plan to install. The distributor assures me that it is a simple plug-out plug-in operation. Is it really that simple? Are there any pitfalls I should be aware of? Is it possible me to retain the 20MB disk in addition to the 80MB disk? I am relatively new to this news group. If these issues were discussed before, I would be grateful if someone can email me the saved discussion. Najmi Jarwala jarwala@ohm.att.com

It would help if you stated what DOS program is the problem. Some seem to work, but I have noted that some programs (Flight Simulator) seem to end up forever refreshing the screen. Speculation: it is as if some "I am done drawing" signal is not being passed back from the screen emulation to the DOS program.

I have never been able to get any type of MS-LOSS "boot-it" floppys/executables to run on a DOS73 card. Whats the secret? Ron Fletcher att!mtgzy!rlf
