if you look at drivers/mips.cpp you'll find the nvram layout
/*
* The following isn't a real dump, but a hand-made nvram image that allows

* Offset Length Variable
* 0x0e 4 netaddr
* 0x12 1 lbaud
* 0x13 1 rbaud
* 0x14 20 bootfile
* 0x28 1 bootmode
* 0x29 1 console
* 0x2a 1 ponmask? or something similar
* 0x2b 3 unused?
* 0x2e 4 resetepc
* 0x32 4 resetra
* 0x36 1 keyswtch
* 0x37 1 flag
* 0x38 8 unused?
