Connecting Cisco 7960G to TFTP Server to perform SIP firmware installation

I have few Cisco 7960G phones that I'm planning to connect to Asterisk. The phones come with Skinny pre-installed. I need to flash them to SIP. I'm primarily following this manual: http://www.asteriskguru.com/tutorials/cisco_7960_ip_phone_configuration.html

I'm stuck at first step. I need to connect the phone to the TFTPd. How do I go about it? It seems to me that I need to connect the phone directly to a PC where TFTPd is running but on top of that, I need to have DHCP server running on the host PC? Is that correct? Otherwise the phone can't get an IP from anywhere. I've seen few mentions on EE and else that people have manually configured the phone with IP but my phones don't give me any control at all.

Anyone know what I should do?

Thanks in advance!

You need to go through the phone config menus and specify the IP address of the TFTP server

Unfortunately I can't access the settings. When I power the device on, it begins with a "Universal Application Loader". It goes through these stages:
1) Configuring VLAN
2) Configuring IP
It gets stuck on the "Configuring IP" message. None of the buttons work. I also performed a Factory Reset according to this manual: https://www.cisco.com/en/US/products/hw/phones/ps379/products_tech_note09186a00800941bb.shtml#pass

OK, so the solution for this problem was this:

Download and install TFTPD32 (http://tftpd32.jounin.net/). I used this specific TFTPd server, because it comes with a built in DHCP server. You need the DHCP server, because the phone tries to get an IP using DHCP. I then connected the phone to a network card on my PC and I had assigned a static IP to the card. I then started the TFTPD server, configured the DHCP server and then powered on the phone. From there on I was able to go into the settings, even though I didn't even need to go into the menu in the end.
