HP Z820 BIOS doesnt recognize SATA0 as a booteable device.

[lerique]

Hello there.

 (sorry, theres no Workstation Board to post this)

I have this Z820 Workstation, with Centos 7.2 S.O. AutoDESK Modification. It was working well until last week, the machine was trasnladed to another office and there was this noise inside, I opened the case and a graphic Card cooler was broken. I removed this card, and boot the machine.

The bios said,

110  - Out of memory space for option ROMS.

The option ROM for the following device was unable to run due to memory constraints. If you choose to continue, one or more PCI devices may not work properly

I repaired the cards cooler, and re install on the pci slot. at boot, the error remains.

I tried disabling the Pci Slot 3 from bios, and the problem stills... then I tryed to disabling Pci Slot 4,5 and 6... And the error stoped.

Then I realized that there was something wrong with a Fiber Card on the Slot 4... I removed this card, resintalled the graphic card, and disabled Slot 4 on BIOS

At boot, there was No error no more... BUT...

Now, when it pass to load O.S., it shows a black screen with a blinking cursor.

I Already tried to install diferent O.S. by booting from a no EFI USB, My BIOS is set on legacy mode from the beggining.

I've fromated, I've cleaned the MBR , installed GRUB2, No windows, or linux O.S. can boot from SATA0

I replaced the 205GB SATA disk with a 1TB SATA Disk, and boot from usb again.. The Workstation Doest boot the O.S.

Ii realized that BIOS can see SATA0 Disk, then I checked Boot Order, USB Drive, and CD SATA1  are elegible for boot, but BIOS doesnt recognize SATA0 as a booteable device.

What can I do with this?

any ideas?
