H00598 - System Hangs with Video ROM Shadowing Disabled SYMPTOM: IBM PC 700 Series 6875 and 6885 may exhibit intermittent system hang conditions with an ISA video adapter installed AND Video ROM Shadowing disabled. PROBLEM ISOLATION AIDS: Access the system Setup Utility and view the Advanced Setup section for ROM Shadowing. If the "C0000h-C7FFFh (Adapter Video BIOS):" entry is Disabled AND an ISA video adapter is being used, this tip applies. FIX: The configuration of a PC 700 system with an ISA video adapter installed requires that video ROM Shadowing is Enabled. Access the Setup Utility Advanced Setup menu and enable Adapter Video BIOS ROM Shadowing. If system hangs persists with this configuration after enabling the video ROM Shadowing, continue normal problem determination procedures to isolate the failing application or FRU.
