Elastix installation on a server ML350 G6

[Planeta_Virtual]

I need to install Elastix 2.3.0 developed 64-bit CentOS 5.7 (Final) on a server HP Proliant ML350 G6. I inserted the CD Elastix distro (CentOS), the installation went smoothly: language settings, interface eth0, DD partition, etc.. I threw the Elastix CD, rebooted and now I can not enter BIOS on the server, no signal on screen, no video, the keypad locks. I can not do anything.

What did I do wrong? Why I can not enter the BIOS?

I appreciate any guidance on
