According to my "Handy Dandy Cisco Confreg Decoder Ring"
(standard issue to Academy instructors) the 9 turns on bits 8 and 11
(leaving 9&10 set to zero) which sets the console baud rate to 4800
& sets disable break key.

The bit functions are as follows (counting from right most position to left):
3 - 0     Boot Field
4          Fast Boot
5          Undefined (according to my decoder)
6          Ignore Configuration on Startup
7          Enable OEM bit (Ignore Cisco Startup Message)
8          Disable Break Key
9          Undefined (according to my decoder)
10        IP Broadcast with all zeros
12-11  Console line speed:  10=1200, 11=2400, 01=4800, 00=9600
13        Boot ROM is Netboot fails
14        IP Broadcast if no net number
15        Enable diagnostic messages and ignore NVRAM

BTW, there used to be a page on CCO which detailed the purpose
of each register bit(s) but I've lost the link and a search using several
different terms was useless.  Anybody still have that link?
