Upon completion of the first row memory test, the memory testing continues with the base memory test.
If the first row test fails, there are several possible failing cases. Two failing scenarios are described in the
following sections.
Case 1
The first row memory test encounters a MBE (Multi Bit Error) in the first populated row of memory configured.
Irrespective of the number of DIMMs populated in the system, if the first row test encounters a MBE, the
BIOS will display an error message on the front panel LCD and halt the system.
User Notification
This memory test occurs during POST and prior to video sync. Therefore, any error found during this test
will result in the following message displayed on the LCD panel.
