NO BOOT

[Ayman Altounji]

Last week I inserted three new memory modules in a Prosignia VS old server. The system booted up but I got a config error. So I powered off ,downloaded the config diskettes from your web, and powered on. To my surprise when I It wasn?t able to boot. There was a blank screen and no beeps. I powered off and removed the new modules with no results. Since then the system does not boot. At last I pushed jumpers 1,4,5, and 6 to "on" position. I powered on and it beeps twice and asks me for a boot diskette. I think it boots but with neither keyboard nor video support.
Is there any chance to recover this old computer?
Thanks.
