Dell 2550 reboots on SLES install..?

Hello, I am attempting to install (SLES) 9 on a Dell PowerEdge 2550 and everytime I get to the GUI part of the install, the server will reboot itself. I am on the latest version on the Dell 2550 bios which is A09. Have you guys seen this happen anywhere else, or have any ideas on why this might be happening? Thank you, Ryan
