I did not realize that.  Now that I went searching for this, saw it 
mentioned in the wiki on the 'XO_Troubleshooting_PowerOn' page.  And 
yes, with the check key pressed, the firmware did print "trying 
sd:\security\devel.sig" and some sort of "invalid" message.  [These 
"stand out" from the other texts if one KNOWS to look for them.]

but I've been seeing icons-drawn-by-firmware anyway.]


I WISH there was a comprehensive description accessible of the 
__iconic__ information shown by the boot process.   For instance, 
for me the green 'olpc' icon disappears from the firmware display 
whenever I have a SD card plugged in (but then I normally *would* 
see an orange 'SD card' icon).  I seem to get the additional red? 
'plugin' icon whenever I have an USB stick or an ethernet adapter 
plugged in.  And I have only vague notions about what the various 
symbols (that can appear underneath an icon) are trying to tell me.
