Seamans) Newsgroups: comp.sys.ibm.pc Subject: EGA addressing Message-ID: <8538@nlm-mcs.arpa> Date: 7 Dec 88 20:46:06 GMT Organization: NLM/LHNCBC, Bethesda, Md. Lines: 29 Over the last year we have been using an imaging board produced by Imaging Technolgy - PFG+. We use a IBM-AT with EGA card and monitor. Problem: The PFG+ board is configured to operate at memory address 0xA000000 which is where the EGA enhanced mode also resides. When we excute the imaging software everything works fine until the program exits. The EGA then attempts to reload its fonts ( I think ) back into the 0xA000000 area which then causes a system hang. It's a pain to turn off and on every time you wish to use the software. Question: If the EGA is in enhanced mode and utilizing the 0xA000000 memory address. Are the 0xB000000 and 0xB800000 areas that are normally used by CGA and MONO now FREE to be used by other processes. - Does anyone see another work around for this addressing problem? BTW - The 0xD000 area has been taken by the IBM 3363 Worm controller card. the 0xC000 seems to be used by the rest of the world.
