Description
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.
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.
CMOS settings are invalid. This error can be resolved by using AMIBIOS Setup.
CMOS contents failed the Checksum check. Indicates that the CMOS data has
been changed by a program other than the BIOS or that the CMOS is not retaining
its data due to malfunction. This error can typically be resolved by using AMIBIOS
Setup.
Description
Keyboard controller BAT test failed. This may indicate a problem with keyboard
controller initialization.
Keyboard is not present or the hardware is not responding when the keyboard
controller is initialized.
PS/2 keyboard support is enabled in the BIOS setup but the device is not detected.
PS/2 mouse support is enabled in the BIOS setup but the device is not detected.
Keyboard controller failure. This may indicate a problem with system hardware.
PS/2 keyboard is locked. User needs to unlock the keyboard to continue the BIOS
POST.
The system has been halted. A reset or power cycle is required to reboot the
machine. This message appears after a fatal error has been detected.
Indicates that <INS> key is pressed during the BIOS POST. The POST will load and
use default CMOS settings.
The password entered does not match the password set in the setup. This condition
may occur for both Supervisor and User password verification.
