Hi Jon, Kent and Jake;
I haven't tried Jon's suggestion yet; Sunday etc.
The processor is a single core and the RAM is 1GB.
The Motherboard is a "mach speed MK8-939A".
The Video card is an Applied Graphics Products
Jeronimo J2/N. Copyright 1995 Etna Corp.
I have forgotten how to find the Video memory size in
Windows and never knew for Linux/Unix.
The BIOS on these systems doesn't display anything
until after the long RAM test. Don't know if these
Video cards even try to display on board memory.
I am using ubuntu 8.04 and EMC2 2.3.4.1.
I tested ubuntu 10.04 LiveCD on these systems. The load
went fine but when it was time for the video all I got was
a blank screen, although ubuntu 8.04 works fine.
The 10.04 works fine on other older systems. Weird huh?
Yes. I didn't know how to spell Schultz and the
spell checker was confused with the missing "c".
Thanks for any and all suggestions.

Start uncovering the many advantages of virtual appliances
and start using them to simplify application deployment and
accelerate your shift to cloud computing.
