Can anyone direct me to an article or source-code listing which would give a system or code for determining which graphics card is installed in a PC (Mono, CGA, Herc, EGA, maybe even VGA)? -- Ted A. Campbell | Duke Divinity School | Durham, NC 27706 | email: tcamp@ecsvax |

The new BIOS Tech Ref has a section on how to distinguish these. The only
problem is that the Herc isn't covered.ralf@B.GP.CS.CMU.EDU (Ralf Brown) (10/18/87)

In order to determine the type of card that is installed in a machine, normally requires opening the machine itself. However, if you are developing your own software, you may use BIOS service 15 to get the current video mode. Video mode seven is for monochrome text. Interrupt 17 (equipment list) may also be used to check on the power up video setting. You may look these up in Norton's Programmer's Guide to the IBM PC or in the MS_DOS programmer's manuals.

The issue of Dr Dobb's Journal that I received yesterday discussed this issue in depth. I assume that it is Nov's Issue. I would call home and make sure but my phone line is being used by my modem at this time! Robert White
