9 | * This test is used to check that the serial output of the firmware | |
e12c08d3 TH |
10 | * (that we provide for some machines) or some small mini-kernels that |
11 | * we provide here contains an expected string. Thus we check that the | |
12 | * firmware/kernel still boots at least to a certain point and so we | |
13 | * know that the machine is not completely broken. | |
