Was able to move another monitor to the misbehaving SC1430.
Plugged into the VGA, this monitor showed the text only BIOS messages.
Unknown why the other monitor wouldn't display the ES1000 text mode video signal, but would display the 8400GS text mode video signal.
Another mystery of the Bermuda Triangle. I guess with an oscilloscope I could figure out what the problem was. Is the ES1000 a bit off frequency, so the big monitor couldn't lock on perhaps?
It used to be that ctrl-ALT-F1 (or other F keys) would put you into a text screen.
It still does, but it's not the plain old 80x25 one fondly recalls from the 20th century.
Instead it is many lines and many characters wide, and I am fairly sure it is an emulation by the linux kernel instead of a plain old graphics card mode.
That said, I have another SC1430, and when I use that monitor on that SC1430, it works just fine in text mode.
One caveat though, I do have a NVIDIA 8400GS in that second unit (through a x16 to x8 pci-e adapter), so it's not an exact A/B comparison, and I don't want to take down the working SC1430 to re-enable its es1000.
I will try moving the VGA cord. Pretty sure it used to show on both VGA plugs back before I went to just the 8400.
Ordered a used plain old PCI SVGA card from Amazon. This SC1430 is pretty much used as a blind server, but some days I may want text mode for management. I certainly want to get it where I don't have to hit F1 to boot anymore, and that probably means some setup screen work.
My guess is the text mode died in the first unit a long ways back, and it just never got noticed because it was always up with the screensaver blanking the screen.. I know it was there when I first installed Linux on it.

Going to call this one solved.

I was able to get a small monitor ocer to the misbehaving SC1430, and on that monitor the BIOS text mode stuff shows up fine.
So for some reason, the big monitor like 8400GS text mode, but doesn't like the built in ES1000 text mode.
It's a mystery, but probably not the SC1430's fault.
At a guess, the ES1000 was using a frequency that the big monitor didn't like.
Maybe the small monitor has a status screen that will tell me how it is being clocked. But really this thread should be marked solved.

Hi,
It sounds like an issue with the lower resolution, either the onboard video not displaying it properly or the monitor. If you go to CLI instead of GUI in linux does it display video? You could also try changing the resolution in the GUI and see if that works. If you have another monitor you could test that as well. We could try our diagnostics but I am not sure if it will boot and display it. http://www.dell.com/support/drivers/us/en/04/DriverDetails/Product/poweredge-1430sc?driverId=5JYC6&osCode=WNET&fileId=2731107884&languageCode=en&categoryId=DI
