Boot stops at blank screen

[cmjb13]

Have a Proliant 1850R that was shipped to our office. The motherboard died and we had to move the drives to another Proliant 1850R. The server had Windows NT 4.0 on it. When booted, I get a "non-system or disk error".

I decided to try to get the data off using Knoppix. I get a blank screen after it says it's trying to load X window. I also get the error "You passed an undefined mode number"

I've tried the following with no success.

vga=normal
knoppix vga=771
knoppix vga=773
knoppix vga=788
knoppix vga=ask
knoppix xmodule=vesa
knoppix screen=800x600
knoppix screen=640x480

Tried 3 different monitors.

I spent all day on this thing with nothing to show for it. I appreciate any help.

Thanks.
