Hi everyone, I have a test machine that I have just formated and re-installed everything, but the fool that I am think I have set the boot sequence wrong and now I can't even get back into the Bios to change it. All I get is power up but nothing seems to kick the drives into action, and I just have a black screen. Is there any reset switch or jumpers that I can reset?
There is no boot sequence at all.
The board is:
AMIBIOS 686, American Megatrends BE89184 (1995)

I really need you help with this one...

If you can't find jumper settings on the web, you can always pull the battery and let the PC sit overnight - that way you are sure that there is no chance of the data remaining.

Good luck!

The least likely problem is the BIOS. (less than 5%)
The first thing to check is that you did not disturb the Video Card with all of the messing around.
The usual causes of black screen are something early in the POST sequence. (Video, Memory, etc.)
If the PC has not booted after the return to default, the next thing is to check the power supply voltages, then try to boot on the floppy, if you can get that far. (The BIOS reset should erase the hard drive settings.)
Regards, Chris
