The KDSETMODE KD_GRAPHICS call is a misnomer, as it doesn't actually put the display into a graphics mode. It just prepares things so that YOU can finish the job. Also, you'll need to refer to the vt(7) manual page, because you'll want to create a virtual terminal for the display. You'll need to program the EGA chipset into the proper mode, etc, yourself. You do this with the inline in[bw]() and out[bw]() functions and a reference manual for the EGA. There is a good book on the EGA available, but I can't find my copy, so I can't give you the title. Maybe somebody else has it? I think its a Microsoft Press book. It can be done, but the support that ISC provides is most basic. -- Rick Richardson | JetRoff "di"-troff to LaserJet Postprocessor|uunet!pcrat!dry2 PC Research,Inc.| Mail: uunet!pcrat!jetroff; For anon uucp do:|for Dhrystone 2 uunet!pcrat!rick| uucp jetroff!~jetuucp/file_list ~nuucp/. |submission forms. jetroff Wk2200-0300,Sa,Su ACU {2400,PEP} 12013898963 "" \d\r\d ogin: jetuucp
