The rt300 seems to use ordinary memory for this, therefore it may be
overwritten. Look at

Hi Holm et al,
So, any more questions that I have missed in the massive mail
conversations that has been last week? :-)
At least one Question I have curently..
You wrote in a post before I should disable that rebooting after an HALT
for debugging purposes... hmm tried that, w/o much luck.
There are 12 dip switches on that board (not 8 like I wrote before) and I
tried to disable that but it doesn't work.
If I power up the machine the value BOOT is empty (...) and HALT is set to
0x03 which should be correct.
If I boot netbsd and it runs on a halt instruction that thing reboots,
BOOT ist then set to eza0 and HALT to 0... and that damn thing is
Is it possible that the values somewhere in the RMA are overwritten from
the Firmware itself or from some netbsd code? What could I try further to
disable this reboots?
section 22.214.171.124 in the manual about this.
