Thank you for coming through with advice, it is much appreciated. I have looked across the web for solutions, and I opened up my main driver which has UEFI BIOS
It's a Gigabyte GA-Z97N-Gaming 5 (Mini ITX).
I tried to first go down the path of using reFind, to no awail, I get the message "InitShellApp: application not started from shell". I searched more on this subject and I could read that I had to use some Shellx64.efi file onto a fat32 usb and boot from it. I tried to change BIOS settings to get it to boot into that shell, but had no luck.
So I then tried to do it the DOS way on my main driver, made the DOS bootable and booting it successfully, only to discover that I cannot, with the message: "ERROR: Failed to initialize PAL. Exiting program." Apparently Intel 3000 or 5000-based boards have optionROM limitations which cause the above error. I do not have the knowledge to solve this.
After that, I kinda got frustrated, so I opened up the Server, which I have the GA-965P-DQ6 with Intel P965+ ICH8R chipset installed. I mounted the card and fired her up, only to see that the SAS bios is initializing AFTER the bios, as opposed to before on the GA-z97N... And with this comes the issue where it says something like "MPT boot ROM. No supported boot devices found."
I am at the brink of giving up, is there something I do wrong? How can I have the SAS card from halting the system and prevent Xpenology to boot from the USB stick?
I assume that if I can find a way to get past the message: "MPT boot ROM. No supported boot devices found." during boot, I can fire up DOS and downgrade.
Many thanks in advance for any support
