6. www artisantg com Theory of Operation Video Controllers The EPC can operate with or without a video controller such as the EXM 13A At power up the BIOS searches the EXM configuration information by slot number starting at O for the first video EXM where the card enable bit is set If one is found it will be initialized and used at power up and the search exits If no video card is enabled in the EXM configuration information a second search is done across the EXM expansion interface beginning at slot 0 looking for an EXM video adapter When a video adapter is found the system will enable it and quit the search If no video controller is present the BIOS operates without one Programs that use the standard operating system and BIOS character output functions run successfully because the output is ignored However programs that rely on specific video modes that write directly into the video RAM or that directly call video BIOS functions will fail Front Panel LED The EPC 26A 27 has one green LED on the front panel This RUN LED is lit whenever the EPC s DRAM memory is being accessed It first comes on at power up and should remain lit as long as the system is running It is normal for the RUN LED to flicker during power up If the processor halts or hangs or runs entirely out of cache the LED will go out Optional Flash SRAM Memory An option exists to purchase the EPC 26A 27 with a combination of 128 KBytes of SRAM
