Motherboard Intel SE 7520BD2D
Intel Xeon Dual processors 2.8 ghz
BIOS Intel Corp
Video Onboard ATI-Rage XL SVGA, 8MB SDRAM
40 Gb Maxtor HD OS only.
Ram 2x1024 MB

Tried.-
1. Remove and reset Battery.
2. Reset bios by pin reset 1-2 to 2-3, and than replace to 1-2.
3. Placed OS DVD/CD in drive and left in. Drive did flash on boot up, but nothing on screen and drive just flashed, not running.
4. Tried leaving rescue disk 1 of 6 in floppy drive. Drive did flash on boot up, but nothing on screen and drive just flashed, not running.
5. Tried with DVD/CD in as well as Floppy disk in. Nothing.

Summary.
Blank Black screen, No signal message.
F8 repeating no result.
Changed screen for a standard 15" same results.
My only guess is that the Video on board is not activated? I did not change anything regarding Video in Bios.
Only sequence of boot up (Primary HD , Secondary, DVD/CD, Third Floppy.
No over clocking,

Originally, I booted up, got the F1, and F2 messages. Did the set up of boot sequence, and was fine.
Rebooted with an add-in HD that was a Samsung 120GB as secondary HD, But OS did not like it so I removed.
I shut down for the day.
In the process of getting a driver for the sound card.
Re-booting, and got the Black Screen.

Checked that slots are properly set, memory reset, Battery checks out.
all connections are properly seated. Even tried another VGA cord.
Both screen test OK on other system.

No Screen, means No getting in to anything.
No bios, No set-up, no reboot into SAFE Mode.

I did try the MAXBLAST disk in the DVD/CD, with same results, No screen signal, therefore can not use.


Suggestions.-
