H132816 - VIDEO CORRUPTION OR SYNC LOSS w/3278/79 ADAPTER SYMPTOM: IBM PC 700 Series 6877 and 6887 may exhibit video corruption in the form of wavy images or even a loss of video sync with a 3278/79 Emulation adapter. Other "older" adapters that are configured to use IRQ 2 may also cause this type of failure symptom. PROBLEM ISOLATION AIDS: The 3278/79 Emulation adapter requires specific system resources to operate correctly. The 3278/79 adapter must utilize IRQ 2 and an 8kb memory page at address "CE00." Adapters that utilize IRQ 2 are also using IRQ 9. IRQ 2 and IRQ 9 are tied together. The video subsystem in the IBM PC 700 uses IRQ 9. FIX: The following "workarounds" are available to minimize the impact that may be caused by the design characteristics of the PC 700 and the 3278/79 adapter: 1) Set IRQ 9 to "ENABLED" in the Activity Monitor section under the Advanced Power Management section of the Configuration/Setup Utility. OR 2) Set the display to "DISABLED" in the Advanced Power Management section of the Configuration Utility. OR 3) Use a DDC Power Manageable monitor. If the error persists, continue normal problem determination procedures.
