28 image transfer completion. This is often useful to catch early boot
29 messages, or to manually interrupt a default boot procedure performed
30 by the second-stage loader.

38 Note that for the encapsulated boot code to be executed, \fIimage\fP
39 must be of type "UART boot" (0x69). Boot images of different types,
41 (type 0x8B), will not work (or not as expected). See \fB-p\fP for a

49 In combination with \fB-b\fP, patches the header in \fIimage\fP prior

64 If used in combination with \fB-b\fP, terminal mode is entered
