mcheck
The mcheck command could also modify the machine check error summary register.
See the mces command for more information about the machine check error
summary register.
Example
In the following example, all machine check and correctable error reporting are
enabled before running the memory test. The errors displayed in this example are
correctable, and without machine checks enabled, these memory errors would be
corrected by the CPU.
EB164> mcheck on
Old BC_CTL = 0x00028051 & BC_CFG = 0x01E21772
New BC_CTL = 0x00020041 & BC_CFG = 0x01E21772
CIA_CACK_EN = 0x8 & CIA_MCR = 0x2001FE21
