Is there a Cisco webpage that lists all of this information? I've searched
and come up dry.

For 0xf921 = 11111001 00100001
Bit 0 = boot from eprom
Bit 5 = Used to set the speed to to 115200
Bit 8 = If a break is sent during boot, go into rommon mode
Bit 11 = Used to set the speed to 115200
Bit 12 = Used to set the speed to 115200
Bit 13 = Boot default ROM if netboot fails
Bit 14 = Used with bit 10 to set net broadcast to <net><ones>
Bit 15 = Enables diagnostics and ignores NVRAM
It looks like someone was doing some sort of boot diagnostics on it.
For 0x3922 = 00111001 00100010
Bit 1 = default netboot file is cisco2-<processor>
Bit 5 = Set console speed to 115200
Bit 8 = Allow break to go into rommon mode
Bit 11 = Set console speed to 115200
Bit 12 = Set console speed to 115200
Bit 13 = Boot default ROM if netboot fails
So, after reboot everything will go back to normal except for bits 5, 11,
and 12. Those are the console speeds
Try going into config mode, go to config line console 0 and enter "speed
9600".
that should freeze up hyperterm (or whatever you are using) until to set
that program to run at 9600 also.
If you do a 'show ver' then you should see
"Configuration register is 0xF921 (will be 0x2102 at next reload)"
hope that helps.
