Spanning tree set up

I have two HP switches (#7 2900, #8 2910al) connected to each other via gigabit. Both switches also connect to a Cisco 2811 at 100 megabit. All three devices have STP enabled with their default options.

It appears that the connection between the switches is the one being blocked. What I want is the 2811 to #7 active and #7 to #8 active. How do I do that?
From the Cisco router
Connected to switch 8:
 Port 53 (FastEthernet1/12) of VLAN1 is forwarding
   Port path cost 19, Port priority 128, Port Identifier 128.53.
   Designated root has priority 32768, address 0004.ea84.5f80
   Designated bridge has priority 32768, address 0018.bac7.4268
   Designated port id is 128.53, designated path cost 19
   Timers: message age 0, forward delay 0, hold 0
   Number of transitions to forwarding state: 1
   BPDU: sent 171990, received 7

Connected to switch 7:
 Port 54 (FastEthernet1/13) of VLAN1 is forwarding 
   Port path cost 19, Port priority 128, Port Identifier 128.54.
   Designated root has priority 32768, address 0004.ea84.5f80
   Designated bridge has priority 32768, address 0018.bac7.4268
   Designated port id is 128.54, designated path cost 19
   Timers: message age 0, forward delay 0, hold 0
   Number of transitions to forwarding state: 1
   BPDU: sent 1649986, received 91

From the HP #8, cable to #7
  17    100/1000T | 20000     128   Blocking   | 0021f7-126580 2     Yes No
 
From HP #7, cable to #8
  17    100/1000T | 20000     128   Forwarding | 0021f7-126580 2     Yes No

Basically, You will have to configure the #7 2900 to be the root bridge by  Lowering the Bridge ID

This link shows you how to drop the Bridge priority (which makes up the Bridge ID) on the HP switch.
