Prelude:
I understand that the problem is probably not unique but all the solutions that I found didn't work out. Probably because its not a desktop/laptop I am working on but its a Terasic DE2i-150 board.
System specifications are here :
http://www.terasic.com.tw/cgi-bin/pa...o=529&PartNo=2
Basically an Atom processor with NM10 express chipset communicating with Altera Cyclone FPGA over PCIe link. The system came preinstalled with a Yocto image in the onboard m-SATA SSD, but the manual does mentions the procedure of installation of other distros as well, with the most preferred being CentOS(as they provide all drivers for CentOS6.x).
Problem statement: Before this I never had to install anything on this board, then one fine day the BIOS went kaput. Replaced with a new BIOS from OEM. Since then I am not able to install CentOS6.7 as the install hangs at probing edd (edd=off to disable). When I try the install with edd=off the installation hangs at
Code:
Loading /images/pxeboot/initrd.img....................................................ready
This is what all I attempted
1. Downloaded the CentOS 6.7 x86-64 DVD1 and DVD2 iso images.
2. Burnt the images to 2 USB sticks (8GB San Disk Cruzer Micro) using UnetBootin software.
3. Attempted the install with the first USB stick containing DVD1 image.
After having read through various problem descriptions on the issue, I tried removing the onboard m-Sata-SSD and attaching a 160GB HDD (preformatted NTFS) on the SATA-2 interface to see if I could atleast get the installation going on the HDD, but to no avail. The BIOS is also a basic one without options to select modes such as AHCI,UEFI etc. I am attaching links to various images which I took during the install process

Here's the Syslinux.cfg file in the USB

PS: I tried installing Puppy linux which went well. The m-SATA was also recognised thus eliminating the possibility of some serious hardware fault limiting the install.
