Message Displayed Microcode Error NVRAM Checksum Bad, NVRAM Cleared Resource Conflict NVRAM Ignored NVRAM Bad Static Resource Conflict PCI I/O conflict PCI ROM conflict PCI IRQ conflict PCI IRQ routing table error Timer Error Refresh timer test failed Interrupt Controller-1 error Interrupt Controller-2 error Description BIOS could not find or load the CPU Microcode Update to the CPU. This message only applies to INTEL CPUs. The message is most likely to appear when a brand new CPU is installed in a motherboard with an outdated BIOS. In this case, the BIOS must be updated to include the Microcode Update for the new CPU. There was an error in while validating the NVRAM data. This causes POST to clear the NVRAM data. More than one system device is trying to use the same non-shareable resources (Memory or I/O). The NVRAM data used to store Plug??n??Play (PnP) data was not used for system configuration in POST. The NVRAM data used to store Plug??n??Play (PnP) data was not used for system configuration in POST due to a data error. Two or more Static Devices are trying to use the same resource space (usually Memory or I/O). A PCI adapter generated an I/O resource conflict when configured by BIOS POST. A PCI adapter generated an I/O resource conflict when configured by BIOS POST. A PCI adapter generated an I/O resource conflict when configured by BIOS POST. BIOS POST (DIM code) found a PCI device in the system but was unable to figure out how to route an IRQ to the device. Usually this error is causing by an incomplete description of the PCI Interrupt Routing of the system. Indicates an error while programming the count register of channel 2 of the 8254 timer. This may indicate a problem with system hardware. BIOS POST found that the refresh timer hardware failed to pass the Refresh Retrace Test. BIOS POST could not initialize the Master Interrupt Controller. This may indicate a problem with system hardware. BIOS POST could not initialize the Slave Interrupt Controller. This may indicate a problem with system hardware. CMOS Message Displayed CMOS Date/ Time Not Set CMOS Battery Low Description The CMOS Date and/or Time are invalid. This error can be resolved by readjusting the system time in AMIBIOS Setup. CMOS Battery is low. This message usually indicates that the CMOS battery needs to be replaced. It could also appear when the user intentionally discharges the CMOS battery. Chapter 4 52
