example <?/22>. To determine the status:
1. Look up the binary conversion in
For example, the first
through 0; the second
2. Next, enter your binary values in
"Binary" column next to the appropriate bit.

with several fields, for example: <?/22><35-559002-
11,35-55900118,A1D6,085C,D96F,D96F>.
These represent, in order: the status byte as discussed above, the boot part number
(35-559002-11), application part number (35-559001-18), boot checksum (A1D6),
RAM parameter checksum (085C), and novram parameter checksum (D96F).
